Over 1 billion young adults are at risk for developing noise-induced hearing loss (NIHL) due to their habit of listening to music at loud levels. The gold standard for detecting NIHL is the audiometric notch around 3,000 to 6,000 Hz observed in pure tone audiogram. However, recent studies suggested that suprathreshold auditory measures might be more sensitive to detect early-stage NIHL in young adults.
Purpose The present study compared suprathreshold measures in individuals with high and low noise exposure backgrounds (NEBs). We hypothesized that individuals with high NEB would exhibit reduced performance on suprathreshold measures than those with low NEB.
Study sample An initial sample of 100 English-speaking healthy adults (18–35 years; females = 70) was obtained from five university classes. We identified 15 participants with the lowest NEB scores (10 females) and 15 participants with the highest NEB scores (10 females). We selected a sample of healthy young adults with no history of middle ear infection, and those in the low NEB group were selected with no history of impulse noise exposure.
Data collection and analysis The study included conventional audiometry, extended high-frequency audiometry, middle ear muscle reflex (MEMR) thresholds, distortion-product otoacoustic emissions (DPOAEs), QuickSIN, and suprathreshold auditory brainstem response (ABR) measures. We used independent sample t-tests, correlation coefficients, and linear mixed model analysis to compare the audiometric measures between the NEB groups.
Results The prevalence of audiometric notch was low in the study sample, even for individuals with high NEB. We found that: (1) individuals with high NEB revealed significantly reduced QuickSIN performance than those with low NEB; (2) music exposure via earphone revealed a significant association with QuickSIN; (3) individuals with high NEB revealed significantly reduced DPOAEs and ABR wave I amplitude compared with individuals with low NEB; (4) MEMR and ABR latency measures showed a modest association with NEB; and (5) audiometric thresholds across the frequency range did not show statistically significant association with NEB.
Conclusion Our results suggest that young adults with high NEB might exhibit impaired peripheral neural coding deficits leading to reduced speech-in-noise (SIN) performance despite clinically normal hearing thresholds. SIN measures might be more sensitive than audiometric notch for detecting early-stage NIHL in young adults.DOI : 10.1055/s-0041-1740362|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=301179

Titre : Low-Level Speech Recognition of Children with Hearing Aids Type de document : Article Auteurs : Jace Wolfe ; Mila Duke ; Sharon E. Miller ; Erin Schafer ; Christine Jones ; Lori Rakita ; Andrea Dunn ; Jarrod Battles ; Sara Neumann ; Jacy Manning Année de publication : 2022 Article en page(s) : p. 196-205 Langues : Anglais (eng) Descripteurs : HE Vinci
Aides auditives ; Evaluation de l'aide auditive ; Reconnaissance de la paroleRésumé : Background
For children with hearing loss, the primary goal of hearing aids is to provide improved access to the auditory environment within the limits of hearing aid technology and the child's auditory abilities. However, there are limited data examining aided speech recognition at very low (40 decibels A [dBA]) and low presentation levels.
Purpose
Due to the paucity of studies exploring aided speech recognition at low presentation levels for children with hearing loss, the present study aimed to (1) compare aided speech recognition at different presentation levels between groups of children with “normal” hearing and hearing loss, (2) explore the effects of aided pure tone average and aided Speech Intelligibility Index (SII) on aided speech recognition at low presentation levels for children with hearing loss ranging in degree from mild to severe, and (3) evaluate the effect of increasing low-level gain on aided speech recognition of children with hearing loss.
Research Design
In phase 1 of this study, a two-group, repeated-measures design was used to evaluate differences in speech recognition. In phase 2 of this study, a single-group, repeated-measures design was used to evaluate the potential benefit of additional low-level hearing aid gain for low-level aided speech recognition of children with hearing loss.
Study Sample
The first phase of the study included 27 school-age children with mild to severe sensorineural hearing loss and 12 school-age children with “normal” hearing. The second phase included eight children with mild to moderate sensorineural hearing loss.
Intervention
Prior to the study, children with hearing loss were fitted binaurally with digital hearing aids. Children in the second phase were fitted binaurally with digital study hearing aids and completed a trial period with two different gain settings: (1) gain required to match hearing aid output to prescriptive targets (i.e., primary program), and (2) a 6-dB increase in overall gain for low-level inputs relative to the primary program. In both phases of this study, real-ear verification measures were completed to ensure the hearing aid output matched prescriptive targets.
Data Collection and Analysis
Phase 1 included monosyllabic word recognition and syllable-final plural recognition at three presentation levels (40, 50, and 60 dBA). Phase 2 compared speech recognition performance for the same test measures and presentation levels with two differing gain prescriptions.
Conclusion
In phase 1 of the study, aided speech recognition was significantly poorer in children with hearing loss at all presentation levels. Higher aided SII in the better ear (55 dB sound pressure level input) was associated with higher Consonant-Nucleus-Consonant word recognition at a 40 dBA presentation level. In phase 2, increasing the hearing aid gain for low-level inputs provided a significant improvement in syllable-final plural recognition at very low-level inputs and resulted in a nonsignificant trend toward better monosyllabic word recognition at very low presentation levels. Additional research is needed to document the speech recognition difficulties children with hearing aids may experience with low-level speech in the real world as well as the potential benefit or detriment of providing additional low-level hearing aid gain.Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=301181

Acouphène ; Anxiété ; Dépression ; Personnalité ; Troubles mentauxRésumé : Background
Psychiatric conditions are common in individuals with tinnitus. Therefore, the ways individuals cope with such conditions and personality can influence the characteristics of tinnitus.
Purpose
The study aims to investigate the direct and indirect effects of resilience, personality traits, and psychiatric symptoms on the tinnitus perception.
Research Design This is a descriptive, cross-sectional, and observational study involving quantitative results.
Study Sample
Thirty-seven individuals with chronic tinnitus (for more than 6 months) sought the tinnitus care service
Data Collection and Analysis
The specific anamnesis of tinnitus, adult self-report questionnaire, resilience scale, big five inventory, Tinnitus Handicap Inventory , and visual analog scale were used. Psychoacoustic measurements (loudness: of tinnitus were performed to characterize the condition in terms of pitch and loudness. The study analyzed the relationship between tinnitus (annoyance, severity, and loudness), psychiatric symptoms, personality, and resilience using multiple mediations.
Results
Resilience did not influence tinnitus severity (BCa: -1.12 to 0.51), annoyance (BCa: -0.10 to 0.11), or loudness (BCa: -0.44 to 0.28) when mediated by anxiety and depression. Additionally, there was only a direct effect of resilience for annoyance There was no direct influence of anxiety and depression on the tinnitus severity , annoyance ), or loudness . However, there was an association of personality traits (neuroticism) with the tinnitus severity and annoyance
Conclusion
Resilience and psychiatric symptoms did not have a direct or indirect influence on the tinnitus annoyance, severity, or loudness. However with a direct association of resilience and annoyance, and neuroticism trait with the tinnitus annoyance and severity. Our results suggest that patients with chronic tinnitus and high neuroticism should receive personalized treatment.Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=301199

Titre : AMBAND Bone-Conduction Headband Type de document : Article Auteurs : Robert H. Margolis ; Janet C. Margolis Année de publication : 2022 Article en page(s) : p. 214-219 Langues : Anglais (eng) Descripteurs : HE Vinci
Audiométrie ; Conduction osseuseRésumé : As bone-conduction thresholds vary with the coupling force between the vibrator and the head, it is important that the coupling force be within the range specified by audiometer standards. The development and validation of AMBAND, an elastic headband for coupling an audiometric bone vibrator to the head, in either the mastoid or forehead position, is described.
Methods
The headband was constructed from woven, fold-over elastic with Velcro attachment points to produce the proper force on the head for various head sizes. Force measurements were made with a digital force gauge on five artificial heads, representing adult females, adult males, children (age 6 years), infants (age 6 months), and newborns with the bone vibrator in the mastoid and forehead positions. Additional measurements were made with the Radioear P-3333 spring band that is in common use.
Results
Force measurements were highly repeatable within a given headband and across headbands. Force measurements for AMBAND were within the range specified by the ANSI S3.6-2018. The Radioear P-3333 spring band produced force levels that exceeded the specified range and had higher variability compared with AMBAND.Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=301202

Etude pilote ; Miroir sonoreRésumé : Tinnitus, the phantom perception of sound, shares many properties with phantom limb pain, in that both may arise as a consequence of sensory deprivation. Prediction errors in multisensory integration, such as induced with mirror box therapy in phantom pain, can reduce phantom percepts.
We evaluated if a device that swaps sound from the right pinna to the left ear canal, and from the left pinna to the right ear canal, can reduce tinnitus. We call this auditory mirror therapy (AMT).
An AMT device consisting of a modified ear defender device with microphones that swaps sounds from left pinna to the right ear canal and from the right pinna to the left ear canal. Participants used the device at home for 2 weeks.
Results There was a significant reduction in THI and in awareness of tinnitus after the AMT intervention.Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=301203

Titre : Simultaneous Multifrequency (SiMFy) Stimulus: A Novel and Reliable Stimulus for Frequency Tuning of Ocular Vestibular-Evoked Myogenic Potentials Type de document : Article Auteurs : Niraj Kumar Singh ; Mamatha Hunsur Ravikumar ; Sandeep Maruthy Année de publication : 2022 Article en page(s) : p. 224-231 Langues : Anglais (eng) Descripteurs : HE Vinci
Fréquence sonore ; Potentiels évoqués vestibulaires myogéniques (cVEMP) (mVEMP) (oVEMP)Résumé : Background Frequency tuning of ocular vestibular evoked myogenic potential (oVEMP) refers to the frequency of tone burst that produces the largest amplitude oVEMP. There is an ever-growing pool of published studies that found the frequency tuning of oVEMP distinctly different in Ménière's disease than the age-matched controls and benign paroxysmal positional vertigo. However, recording oVEMP in response to many frequencies makes an already lengthy vestibular test battery even more cumbersome and time-consuming.
Purpose The aim of this study was to develop a novel time-saving stimulus that produces reliable results.
Research Design Prospective study.
Study Sample The study included 25 young, healthy adults.
Data Collection The tone-bursts of 2000, 1500, 1000, 750, 500, and 250 Hz were generated and sequenced in this order to prepare a stimulus for simultaneous multifrequency (SiMFy) oVEMP. The response parameters of SiMFy and conventional oVEMP methods were compared.
Results No significant difference in peak-to-peak amplitude and frequency tuning existed between conventional and SiMFy oVEMP (p > 0.05). SiMFy had better test–retest reliability and was less time-consuming than the conventional oVEMP.Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=301206

Titre : The Influence of Motoric Maneuvers on Cervical Vestibular Evoked Myogenic Potentials (cVEMPs) Type de document : Article Auteurs : Kathleen M.

Electromyographie ; Potentiels évoqués vestibulaires myogéniques (cVEMP) (mVEMP) (oVEMP) ; Système vestibulaireMots-clés : Muscle sterno-cléido-mastoïdien Résumé : Background The cervical vestibular evoked myogenic potential (cVEMP) is a vestibular response that is produced by the saccule in response to intense, often low-frequency, short-duration auditory stimuli, and is typically recorded from a contracted sternocleidomastoid (SCM) muscle. Previous research has shown that the amplitude of the cVEMP is related to the amount of SCM electromyographic (EMG) activity.
Purpose The aim of this study was to determine the influence of various remote motoric maneuvers on the amplitude of the cVEMP, as well as whether they influence the level of SCM EMG activity.
Research Design The cVEMP was recorded from the left SCM muscle to left ear stimulation, in response to the SCM condition, as well as three different motoric maneuvers (jaw clench, eye closure, and the Jendrassik maneuver). EMG activity was also varied between 50, 75, and 100% of maximal EMG activity.
Study Sample Data from 14 healthy subjects, with a mean age of 25.57 years (standard deviation = 5.93 years), was included in the present study.
Data Collection and Analysis Mean latency and amplitude of the cVEMP were compared across the four conditions and varying magnitudes of EMG contraction. SPSS 26 was used to statistically analyze the results.
Results cVEMP latency did not vary across condition. cVEMP amplitude decreased with decreasing EMG magnitude. SCM contraction with jaw clench produced the largest increase in cVEMP amplitude; however, this condition was not significantly different from the SCM condition alone. SCM contraction with the Jendrassik maneuver produced a cVEMP amplitude that was similar and not statistically different from SCM contraction alone, and the addition of the eye closure maneuver to SCM contraction resulted in the lowest cVEMP amplitude, which was found to be statistically different from the standard SCM condition at 100 and 75% EMG activity. The amplitude relationship across the conditions was not found to vary with changes in EMG activity; however, a significant increase in EMG amplitude was found during the 50% muscle contraction condition when subjects performed the Jendrassik maneuver in addition to the standard SCM contraction.
Conclusions The addition of the eye closure maneuver to SCM contraction resulted in a significant decrease in cVEMP amplitude, while the addition of the Jendrassik maneuver resulted in a significant increase in EMG activity at the lowest level of SCM activation (i.e., 50%). Additional research is necessary to determine how motoric maneuvers influence the cVEMP amplitude, and whether the results are also dependent on how SCM contraction is being produced (e.g., while supine vs. sitting).Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=301748

Microphone adaptatif directionnel (ADM) ; Technologie d'assistanceRésumé : Purpose Cochlear implant (CI) recipients often experience speech recognition difficulty in noise in small group settings with multiple talkers. In traditional remote microphones systems, one talker wears a remote microphone that wirelessly delivers speech to the CI processor. This system will not transmit signals from multiple talkers in a small group. However, remote microphone systems with multiple microphones allowing for adaptive beamforming may be beneficial for small group situations with multiple talkers. Specifically, a remote microphone with an adaptive multiple-microphone beamformer may be placed in the center of the small group, and the beam (i.e., polar lobe) may be automatically steered toward the direction associated with the most favorable speech-to-noise ratio. The signal from the remote microphone can then be wirelessly delivered to the CI sound processor. Alternately, each of the talkers in a small group may use a remote microphone that is part of a multi-talker network that wirelessly delivers the remote microphone signal to the CI sound processor. The purpose of this study was to compare the potential benefit of an adaptive multiple-microphone beamformer remote microphone system and a multi-talker network remote microphone system.
Method Twenty recipients, ages 12 to 84 years, with Advanced Bionics CIs completed sentence-recognition-in-noise tasks while seated at a desk surrounded by three loudspeakers at 0, 90, and 270 degrees. These speakers randomly presented the target speech while competing noise was presented from four loudspeakers located in the corners of the room. Testing was completed in three conditions: 1) CI alone, 2) Remote microphone system with an adaptive multiple-microphone beamformer, and 3) and a multi-talker network remote microphone system each with five different signal levels (15 total conditions).
Results Significant differences were found across all signal levels and technology conditions. Relative to the CI alone, sentence recognition improvements ranged from 14–23 percentage points with the adaptive multiple-microphone beamformer and 27–47 percentage points with the multi-talker network with superior performance for the latter remote microphone system.
Conclusions Both remote microphone systems significantly improved speech recognition in noise of CI recipients when listening in small group settings, but the multi-talker network provided superior performance.Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=301751

Acceptable Noise Level (ANL) ; Aides auditives ; Troubles sensitifsRésumé : Background Hearing aid manufacturers offer several different levels of technology that vary in sophistication and cost. It would stand to reason that higher technology hearing aids would provide greater benefit in the daily life of the user; however, research does not support this assumption for all users. Recent research in experienced hearing aid users indicated noise acceptance and satisfaction for speech in a large group were significantly improved when using the premium devices and suggested noise acceptance may be useful when comparing hearing aid technology levels.
Purpose The purpose of this study was to determine the effect of hearing aid technology level on listener outcome measures for new hearing aid users.
Research Design A repeated measures, single-blinded research design was utilized.
Study Sample Twenty-four adults with no previous hearing aid experience were recruited using flyers posted at the University of Tennessee Audiology Clinic and on social media (19 males, 5 females). The average age of the participants was 61 years (48–81 years).
Data Collection and Analysis Participants completed two, 4-week trial periods using Unitron T Moxi Fit FLEX:TRIAL devices programmed with basic or premium technology. Following each trial, laboratory evaluations were conducted using the QuickSIN, Hearing in Noise Test (HINT), and the Acceptable Noise Level (ANL). Subjective data was obtained using the Speech, Spatial, and Qualities of Hearing Short Form, satisfaction ratings, and preference. Data was analyzed using one-way repeated-measures analysis of variance.
Results Speech perception results did not reveal significant differences between technology level on the HINT or QuickSIN; however, ANL was significantly improved for the premium devices. Subjective results revealed significantly improved satisfaction for speech in a large group and overall preference when using premium technology.
Conclusion Group data revealed similar outcomes between technology levels on most measures; however, noise acceptance, satisfaction for speech in a large group, and overall preference were significantly improved when using the premium devices. Individual characteristics such as noise acceptance, age, and degree of hearing loss may be useful when comparing hearing aid technology levels for new hearing aid users.Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=301759

Titre : Personal Characteristics Associated with Ecological Momentary Assessment Compliance in Adult Cochlear Implant Candidates and Users Type de document : Article Auteurs : Yu-Hsiang Wu ; Elizabeth Stangl ; Jacob J.

Évaluation écologique instantanée ; Implants cochléaires ; Observance par le patientRésumé : Background Ecological momentary assessment (EMA) often places high physical and mental burden on research participants compared with retrospective self-reports. The high burden could result in noncompliance with the EMA sampling scheme protocol. It has been a concern that certain types of participants could be more likely to have low compliance, such as those who have severe hearing loss and poor speech recognition performance, are employed, are not familiar with technologies used to implement EMA (e.g., smartphones), and have poorer cognitive abilities. Noncompliance dependent on personal characteristics could negatively impact the generalizability of EMA research.
Purpose This article aims to determine personal characteristics associated with EMA compliance in a group of adult cochlear implant (CI) candidates and users.
Research Design An observational study.
Study Sample Fifty-eight adults who were either scheduled to received CIs or were experienced CI users completed the study.
Data Collection and Analysis Participants conducted smartphone-based EMA designed to assess an individual's daily auditory ecology for 1 week. EMA compliance was quantified using two metrics: the number of completed surveys and the response rate to the notification delivered by the EMA app. Personal characteristics (i.e., predictors) included age, gender, CI status (candidate or user), employment status (employed or not employed), smartphone ownership, speech recognition performance, social network size, level of depressive symptoms, and neurocognitive abilities. A word recognition test, questionnaires, and a test battery of neurocognitive assessments were used to measure the predictors. We used negative binomial regression and logistic mixed models to determine the factors associated with the number of completed surveys and the response rate, respectively. We hypothesized that, for example, employed participants with poorer speech recognition performance would have lower compliance.
Results Contrary to the hypothesis, word recognition score was negatively associated with the number of completed surveys (p = 0.022). Holding all other variables constant, a 10-point (i.e., 10%) word recognition score decrease was associated with an 11% increase in the number of completed surveys.

Conclusion For CI candidates and users, EMA compliance could be affected by personal characteristics such as speech recognition performance and employment status. Because (1) participants with poorer speech recognition performance do not necessarily have lower compliance and (2) most personal characteristics investigated in the present study (e.g., age, gender, smartphone ownership, and neurocognitive abilities) do not predict compliance, a wide range of participants could successfully conduct smartphone-based EMA.Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=301774

Titre : Influence of Audibility and Distortion on Recognition of Reverberant Speech for Children and Adults with Hearing Aid Amplification Type de document : Article Année de publication : 2022 Article en page(s) : p. 170 - 180 Langues : Anglais (eng) Descripteurs : HE Vinci
Adulte ; Aides auditives ; Déficience auditive ; Enfant (6-12 ans) ; Perception de la paroleRésumé : Background
Adults and children with sensorineural hearing loss (SNHL) have trouble understanding speech in rooms with reverberation when using hearing aid amplification. While the use of amplitude compression signal processing in hearing aids may contribute to this difficulty, there is conflicting evidence on the effects of amplitude compression settings on speech recognition. Less clear is the effect of a fast release time for adults and children with SNHL when using compression ratios derived from a prescriptive procedure.
Purpose
The aim of the study is to determine whether release time impacts speech recognition in reverberation for children and adults with SNHL and to determine if these effects of release time and reverberation can be predicted using indices of audibility or temporal and spectral distortion.
Research Design
This is a quasi-experimental cohort study. Participants used a hearing aid simulator set to the Desired Sensation Level algorithm m[i/o] for three different amplitude compression release times. Reverberation was simulated using three different reverberation times.
Participants
Participants were 20 children and 16 adults with SNHL.
Data Collection and Analyses
Participants were seated in a sound-attenuating booth and then nonsense syllable recognition was measured. Predictions of speech recognition were made using indices of audibility, temporal distortion, and spectral distortion and the effects of release time and reverberation were analyzed using linear mixed models.
Results
While nonsense syllable recognition decreased in reverberation release time did not significantly affect nonsense syllable recognition. Participants with lower audibility were more susceptible to the negative effect of reverberation on nonsense syllable recognition.
Conclusion
We have extended previous work on the effects of reverberation on aided speech recognition to children with SNHL. Variations in release time did not impact the understanding of speech. An index of audibility best predicted nonsense syllable recognition in reverberation and, clinically, these results suggest that patients with less audibility are more susceptible to nonsense syllable recognition in reverberation.Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=301828

Titre : Video Head Impulse Test in Persons with Blindness: Feasibility and Outcomes Type de document : Article Auteurs : Raghav Hira Jha ; Niraj Kumar Singh ; Prawin Kumar Année de publication : 2022 Article en page(s) : p. 116 - 124 Langues : Anglais (eng) Descripteurs : HE Vinci
Cécité ; Réflexe vestibulo-oculaire (VOR) ; Saccades ; Test d'impulsion rotatoire de la tête (vHIT)Résumé : Background
To achieve balance, persons with blindness (PWB) use proprioceptive and vestibular cues rather than the visual system; however, PWB are equally susceptible to acquire vestibular disorders. Reliable assessments of the vestibular system in PWB are essential to determine the presence or absence of vestibular disorders.
Purpose
The saccular and the utricular functioning can be assessed using cervical vestibular-evoked myogenic potential and ocular vestibular-evoked myogenic potential, respectively. Evaluation of the functional integrity of the semicircular canals requires an assessment of the vestibular ocular reflex; however, this can be challenging in PWB. Video head impulse test (vHIT) assesses the vestibular ocular reflex (VOR) elicited against the natural high-frequency head movement in the planes of all six semicircular canals. This study aimed to explore the feasibility and outcomes of administering vHIT in PWB.
Research Design
Standard (static) groups comparison.
Study Sample
Nineteen young PWB and 23 age-matched adults with “normal” vision (control group) were included in the study.
Data Collection and Analyses
PWB underwent vHIT once, while the control group was tested in three conditions; condition 1 was used to simulate blindness for the control group, where vHIT was done in a pitch-dark room without prior instructions; condition 2 included vHIT testing in daylight, without a fixed visual target and any instructions; and condition 3 involved vHIT in daylight in the presence of a set visual target and with standard instructions to maintain visual focus on the visual target.
Results
The VOR gain was abnormal in the PWB group for all the canals. Among the PWB, the lateral canals (mean = 0.63) had the best VOR gain, followed by the anterior canals (mean = 0.53) and the posterior canals (mean = 0.31). In the control group, the VOR gain was significantly reduced in condition 1. There was no significant difference between the VOR gain in the PWB group and the control group in condition 1 for the lateral and the anterior canals. A higher proportion of participants in the PWB group had the presence of refixation saccades.
Conclusion
VOR is significantly reduced in PWB but not completely absent. There may be a need to develop normative data for blind individuals to decide whether or not a person with blindness has a vestibular dysfunction, specifically a VOR deficit.Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=301830

Titre : The Effect of Music Genre and Music-Preference Dimension on Acceptable Noise Levels in Listeners with ‘Normal’ Hearing Type de document : Article Auteurs : Susan Gordon-Hickey ; Melinda F. Bryan Année de publication : 2022 Article en page(s) : p. 125 - 133 Langues : Anglais (eng) Descripteurs : HE Vinci
Bruit ambiant ; Musique ; Seuil auditifRésumé : Background
The acceptable noise level (ANL) is the maximum level of background noise that an individual is willing to accept while listening to speech. The type of background noise does not affect ANL results except for music.
Purpose
The purpose of this study was to determine if ANL differed due to music genre or music genre preference.
Research Design
A repeated-measures experimental design was employed.
Study Sample
Thirty-three young adults with normal hearing served as listeners.
Data Collection and Analysis
Most comfortable listening level and background noise level were measured to twelve-talker babble and five music samples from different genres: blues, classical, country, jazz, and rock. Additionally, music preference was evaluated via rank ordering of genre and by completion of the Short Test of Music Preference (STOMP) questionnaire.
Results
The ANL for music differed based on music genre; however, the difference was unrelated to music genre preference. Also, those with low ANLs tended to prefer the intense and rebellious music-preference dimension compared with those with high ANLs.
Conclusions
For instrumental music, ANL was lower for blues and rock music compared with classical, country, and jazz. The differences identified were not related to music genre preference; however, this finding may be related to the music-preference dimension of intense and rebellious music. Future work should evaluate the psychological variables that make up music-preference dimension to determine if these relate to our ANL.Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=301831

Titre : Hearing Screening Age Considerations for Adults: National Health and Nutrition Examination Survey Type de document : Article Auteurs : Jaxon Jordan ; Rachael R. Baiduc ; Christopher Spankovich Année de publication : 2022 Article en page(s) : p. 58 - 65 Langues : Anglais (eng) Descripteurs : HE Vinci
Déficience auditive ; Épidémiologie ; EvaluationRésumé : Background
The United States Preventative Service Taskforce recently determined that there was insufficient evidence to recommend hearing screening in adults.
Purpose
To determine the age to screen adults in the U.S. for hearing loss and identify factors related to increased odds of hearing loss.
Research Design
Epidemiological Cross-Sectional Study.
Study Sample
Data from 3,409 individuals aged 20–69 years(y) were analyzed from the 1999–2000 and 2000–2002 cycles of the National Health and Nutrition Examination Survey (NHANES).
Data Collection and Analysis
Hearing sensitivity from 0.5–8 kHz was assessed and hearing loss was defined as pure tone average 0.5, 1, 2, 4 kHz (PTA4) > 15 dBHL for the worse ear. Thresholds were examined separately for men and women in 2-year intervals. A multivariate ordinal regression model adjusting for age, sex, race/ethnicity, and education was used to examine relationship to determinants.
Results
Slight (>15 dBHL) hearing loss based on threshold at a single audiometric frequency was first evident in males aged 28–29y. For females, this occurred at age 34–35y. The age at which average PTA4 increased above 15 dBHL (slight hearing loss) was 46–47y for males and 56–57y for females. Multivariate ordinal regression revealed the following “high risk” factors: increased age, male sex, tinnitus, perceived hearing loss, and diabetes.
Conclusions
For the function of primary prevention, these data suggest screening should initiate at ∼30y for males and 35y for females, the ages when average hearing thresholds at a single frequency can be classified as slight hearing loss. For secondary prevention, the recommended screening ages are higher – 45y for males and 55y for females. Hearing screening is recommended for asymptomatic adults, especially those with high risk factors. Our results also highlight the limitations of PTA4 in identifying early indices of hearing loss.DOI : 10.1055/s-0041-1735520|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=297359

Microphone adaptatif directionnel (ADM)Résumé : Children with hearing loss frequently experience difficulty understanding speech in the presence of noise. Although remote microphone systems are likely to be the most effective solution to improve speech recognition in noise, the focus of this study centers on the evaluation of hearing aid noise management technologies including directional microphones, adaptive noise reduction (ANR), and frequency-gain shaping. These technologies can improve children's speech recognition, listening comfort, and/or sound quality in noise. However, individual contributions of these technologies as well as the effect of hearing aid microphone mode on localization abilities in children is unknown.
Purpose
The objectives of this study were to (1) compare children's speech recognition and subjective perceptions across five hearing aid noise management technology conditions and (2) compare localization abilities across three hearing aid microphone modes.
Research Design
A single-group, repeated measures design was used to evaluate performance differences and subjective ratings.
Study Sample
Fourteen children with mild to moderately severe hearing loss.
Data Collection and Analysis
Children's sentence recognition, listening comfort, sound quality, and localization were assessed in a room with an eight-loudspeaker array.
Results and Conclusion
The use of adaptive directional microphone technology improves children's speech recognition in noise when the signal of interest arrives from the front and is spatially separated from the competing noise. In contrast, the use of adaptive directional microphone technology may result in a decrease in speech recognition in noise when the signal of interest arrives from behind. The use of a microphone mode that mimics the natural directivity of the unaided auricle provides a slight improvement in speech recognition in noise compared with omnidirectional use with limited decrement in speech recognition in noise when the signal of interest arrives from behind. The use of ANR and frequency-gain shaping provide no change in children's speech recognition in noise. The use of adaptive directional microphone technology, ANR, and frequency-gain shaping improve children's listening comfort, perceived ability to understand speech in noise, and overall listening experience. Children prefer to use each of these noise management technologies regardless of whether the signal of interest arrives from the front or from behind. The use of adaptive directional microphone technology does not result in a decrease in children's localization abilities when compared with the omnidirectional condition. The best localization performance occurred with use of the microphone mode that mimicked the directivity of the unaided auricle.DOI : 10.1055/s-0041-1735802|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=297360

Titre : Tinnitus Assessment and Management: A Survey of Practicing Audiologists in the United States and Canada Type de document : Article Auteurs : Adam Sheppard ; Christina Stocking ; Jinyu Qian ; Wei Sun Année de publication : 2022 Article en page(s) : p. 75 - 81 Note générale : 10.1055/s-0041-1736576 Langues : Anglais (eng) Descripteurs : HE Vinci
Traitement de l'acouphèneRésumé : Tinnitus is a prevalent auditory disorder that can become severely debilitating. Despite decades of investigation, there remains no conclusive cure for tinnitus. Clinical practice guidelines (CPGs) are available for assessing and managing tinnitus. Even though such guidelines have been available for several years, the degree that audiologists adhere to them has remained unexplored.
Purpose of Study
To determine what clinical practices are commonly used by audiologists in the assessment and management of the patient population with tinnitus, we administered an online survey to audiologists practicing in the United States and Canada.
Results
Among the audiologists that completed the survey and were included in the final analysis (n = 61), 70% were from the United States and 30% were from Canada. The audiologists represented a wide range of clinical experience (1–35 years). On average, those who completed the survey were relatively confident in their ability to assess and manage tinnitus patients indicated by a 0 to 100 Likert scale, with 0 representing no confidence (mean 72.5, ± 21.5 standard deviation). The most commonly reported tinnitus assessment tools were pure tone audiogram (0.25–8 kHz), administration of standardized questionnaires, and tinnitus pitch and loudness matching. Approximately half (55%) of audiologists indicated they include otoacoustic emissions, while less audiologists (
Conclusion
Few audiologists administer a truly comprehensive tinnitus assessment and ∼20% indicated not recommending counseling or sound therapy to manage tinnitus. The results are discussed in the context of what is explicitly indicated in published CPGs, professional organization recommendations, and recent findings of peer-reviewed literature.DOI : 10.1055/s-0041-1736576|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=297361

Titre : Psychometric Evaluation of a Patient Experience Questionnaire (PEQ) for Outpatient Appointments: Analysis Using Data from a U.K. National Health Service Audiology Department Type de document : Article Auteurs : Hashir Aazh ; Anna Pepler ; Karen Lammaing ; Brian C. J. Moore ; Ali A. Danesh Année de publication : 2022 Article en page(s) : p. 82 - 91 Note générale : 10.1055/s-0041-1736575 Langues : Anglais (eng) Descripteurs : HE Vinci
Enquêtes et questionnaires ; Psychométrie ; Vécu du patientRésumé : The Audiology Department at the Royal Surrey NHS Foundation Trust (RSFT), United Kingdom, developed a patient experience questionnaire (PEQ) to assess and compare patients' experiences of attending a wide range of appointments (e.g., hearing assessment, hearing aid fitting, hearing aid review, tinnitus therapy, balance assessment, and balance rehabilitation).
Purpose
The aim of this study was to assess the psychometric properties of the PEQ. The PEQ is a unidimensional instrument with four items that assess a patient's experience of an outpatient appointment.
Research Design
Retrospective cross-sectional study.
Study Sample
Patients attending appointments for audiology services at RSFT between January and March 2020.
Data Collection and Analysis All patients (n = 656) attending appointments for audiology services at RSFT during randomly selected days between January and March 2020 were given the questionnaire to complete themselves (PEQ-self) or to complete on their child's behalf (PEQ-parent). The factor structures for the PEQ-self and PEQ-parent were assessed separately, using confirmatory factor analysis. A multiple-causes, multiple-indicators (MIMIC) model was fitted to explore potential bias due to gender and age. Internal consistency was assessed using Cronbach's α. The bivariate correlations between PEQ scores and other variables were evaluated using the nonparametric Spearman correlation coefficient. Floor and ceiling effects were assessed using the distribution of total scores.
Results Confirmatory factor analysis revealed that a one-factor model gave a close fit to the data for both the self and parent versions. Cronbach's α for the total score was 0.77 for the PEQ-self and 0.86 for the PEQ-parent. The MIMIC model showed no significant direct effects of age or gender for either version.
Conclusions
Both the PEQ-self and PEQ-parent questionnaire can be reliably used to measure patients' experiences of outpatient audiology appointments. Future studies should aim to assess the psychometric properties of the PEQ-self and PEQ-parent for a range of outpatient appointments other than audiology.DOI : 10.1055/s-0041-1736575|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=297362

Titre : Measures of Subjective Tinnitus: What Does Visual Analog Scale Stand for? Type de document : Article Auteurs : Sung Wan Byun ; Seung-Ho Shin Année de publication : 2022 Article en page(s) : p. 92 - 97 Note générale : 10.1055/s-0041-1736649 Langues : Anglais (eng) Descripteurs : HE Vinci
Acouphène ; Echelle visuelle analogique (EVA) ; Enquêtes et questionnairesRésumé : Patients with tinnitus may have different severity levels of tinnitus distress. Visual analog scale (VAS) is a simple method to measure the extent of subjective distress caused by tinnitus. It includes ratings of tinnitus loudness, awareness, annoyance, and impact of tinnitus on life.
Purpose
The purpose of this study was to evaluate what led to different distress levels in patients with bilateral tinnitus by analyzing the relationships among all subscales of VAS scores for tinnitus distress and the documented variables.
Research Design This study was a retrospective cohort study.
Study Sample
The medical records of 268 patients who visited a tinnitus clinic between March and December 2020 were reviewed.
Data Collection and Analysis Epidemiologic characteristics, subjective tinnitus distress factors including tinnitus loudness, awareness, annoyance, and impact of tinnitus on life, questionnaire results including those from the Tinnitus Handicap Inventory (THI) and Beck Depression Inventory (BDI), and audiometric profiles were documented. Based on a bivariate analysis between variables and subtypes of subjective tinnitus distress, stepwise logistic regression was performed to identify potential influencing factors for aggravating each subtype.
Results
Data from a total of 122 patients with bilateral tinnitus were collected. The cohort included 77 males and 45 females with a mean age of 51.16 ± 13.50 years. Tinnitus loudness was associated with an accompanying headache (p
Conclusion
Psychologic complaints are mainly associated with tinnitus loudness and annoyance. On the other hand, hearing loss is linked with tinnitus awareness and its impact on life. Thus, an individualized, sequential approach that considers different subtypes of tinnitus severity to assess subjective tinnitus distress is needed.DOI : 10.1055/s-0041-1736649|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=297366

Aide à la communication ; COVID-19 ; Masque (équipement de protection) ; SurditéRésumé : The COVID-19 pandemic has made wearing face masks a common habit in public places. Several reports have underlined the increased difficulties encountered by deaf people in speech comprehension, resulting in a higher risk of social isolation and psychological distress.
Purpose
To address the detrimental effect of different types of face masks on speech perception, according to the listener hearing level and background noise.
Research Design
Quasi-experimental cross-sectional study.
Study Sample
Thirty patients were assessed: 16 with normal hearing [NH], and 14 hearing-impaired [HI] with moderate hearing loss.
Data Collection and Analysis
A speech perception test (TAUV) was administered by an operator trained to speak at 65 dB, without a face mask, with a surgical mask, and with a KN95/FFP2 face mask, in a quiet and in a noisy environment (cocktail party noise, 55 dB). The Hearing Handicap Index for Adults (HHI-A) was administered twice, asking subjects to complete it for the period before and after the pandemic outburst. A 2-way repeated-measure analysis of variance was performed.
Results
The NH group showed a significant difference between the no-mask and the KN95/FFP2-mask condition in noise (p = 0.01). The HI group showed significant differences for surgical or KN95/FFP2 mask compared with no-mask, and for KN95/FFP2 compared with surgical mask, in quiet and in noise (p
Conclusion
Face masks have a detrimental effect on speech perception especially for HI patients, potentially worsening their hearing-related quality of life.DOI : 10.1055/s-0041-1736577|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=297367

Déficience auditive ; Impédancemétrie ; Implants cochléaires ; TélémétrieRésumé : Impedance is a basic parameter registered at any cochlear implant (CI) fitting section. It is useful in monitoring electrode functioning and the status of the surrounding anatomical structures.
Purpose
The main aim of this study is to evaluate the 5-year impedance-value trend in patients affected by congenital genetically determined profound hearing loss implanted with Cochlear Nucleus devices.
Research Design
Observational, retrospective, monocentric study.
Study Sample
Twenty-seven consecutive patients (9 females: 12.0 ± 7.6 years old; range: 4.2–40.4) with genetic diagnosis of GJB2 mutation causing congenital profound hearing loss who underwent cochlear implantation from 2010 to 2020 with good auditory benefit.
Intervention
Impedance values of the CIs were obtained from the CIs' programming software that registers those parameters for each follow-up section of each patient.
Data Collection and Analysis
Impedance values were measured over time (activation, 6, 12, 24, and 60 months after cochlear implantation), for each of the 22 electrodes, in common ground, monopolar 1, monopolar 2, and monopolar 1 + 2 stimulation modes.
Results
A significant variation was found between CI activation and 6-month follow-up. This difference was found for each of the 22 electrodes. Electrodes 1 to 4 showed higher impedance values compared with all other electrodes in each time interval. Repeated-measures analysis of variance ruled out significant variations in impedance values from 6-month to 5-year follow-up.
Conclusions
Impedance values were extremely stable after activation, at least for the first 5 years. In these cases, even minimal impedance variations should be carefully evaluated for their possible implications on hearing performance.DOI : 10.1055/s-0041-1739290|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=297368

Audiologie ; Audiométrie ; Automatisation ; Bruit ; Diagnostic ; Perte d'auditionRésumé : Background
Up to 80% of audiograms could be automated which would allow more time for provision of specialty services. Ideally, automated audiometers would provide accurate results for listeners with impaired hearing as well as normal hearing. Additionally, accurate results should be provided both in controlled environments like a sound-attenuating room but also in test environments that may support greater application when sound-attenuating rooms are unavailable. Otokiosk is an iOS-based system that has been available for clinical use, but there are not yet any published validation studies using this product.
Purpose
The purpose of this project was to complete a validation study on the OtoKiosk automated audiometry system in quiet and in low-level noise, for listeners with normal hearing and for listeners with impaired hearing.
Research Design
Pure tone air conduction thresholds were obtained for each participant for three randomized conditions: standard audiometry, automated testing in quiet, and automated testing in noise. Noise, when present, was 35 dBA overall and was designed to emulate an empty medical exam room.
Study Sample
Participants consisted of 11 adults with hearing loss and 15 adults with normal hearing recruited from the local area.
Data Collection and Analysis
Thresholds were measured at 500, 1,000, 2,000, and 4,000 Hz using the Otokiosk system that incorporates a modified Hughson-Westlake method. Results were analyzed using descriptive statistics and also by a linear mixed-effects model to compare thresholds obtained in each condition.
Results
Across condition and participant group 73.6% of thresholds measured with OtoKiosk were within ± 5 dB of the conventionally measured thresholds; 92.8% were within ± 10 dB. On average, differences between tests were small. Pairwise comparisons revealed thresholds were ∼3.5–4 dB better with conventional audiometry than with the mobile application in quiet and in noise. Noise did not affect thresholds measured with OtoKiosk.
Conclusions
The OtoKiosk automated hearing test measured pure tone air conduction thresholds from 500 to 4,000 Hz at slightly higher thresholds than conventional audiometry, but less than the smallest typical 5 dB clinical step-size. Our results suggest OtoKiosk is a reasonable solution for sound booths and exam rooms with low-level background noise.DOI : 10.1055/s-0041-1728778|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=297128

Conclusion
In the closed ears, no remarkable negative factors were found. Transducer type had a significant influence on the continued-use rate in the nonclosed ears including the ears with chronic continuous otorrhea, although the purchase rate of CC-HAs in the bilateral chronic continuous otorrhea group was comparable to the closed ears.DOI : 10.1055/s-0041-1733965|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=297130

Acceptable Noise Level (ANL) ; Background Noise Level (BNL) ; Bruit ambiant ; TransducteursRésumé : Purpose
The aim of this study was to assess the impact of transducer (loudspeaker, supra-aural headphones, and insert earphones) selection on the acceptable noise level (ANL).
Study Sample
Thirty young adults with normal hearing who reported difficulty with background noise served as participants.
Research Design
A repeated-measures experimental design was employed.
Data Collection and Analysis Most comfortable listening level (MCL) and background noise level (BNL) were measured for all participants using three transducers (loudspeaker, supra-aural headphones, and insert earphones). ANL was computed as the difference between the mean MCL and the mean BNL.
Results Analytical statistics revealed that ANL did not differ due to the transducer used. However, there were statistically significant differences found for MCL and BNL across transducers.
Conclusions Results of this study indicate that ANL is not vulnerable to the selection of transducer and that ANLs can be compared across transducer types. Researchers should cautiously interpret findings across studies when discussing the base measures of MCL and BNL as these may be influenced slightly by transducer selection.DOI : 10.1055/s-0041-1735254|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=297132

Emissions otoacoustiques évoquées (OEA)(OAE)Mots-clés : Suppression controlatérale Résumé : Background
A standard method and parameter study were performed for the contralateral suppression test.
Purpose
Our study aimed to determine the contralateral transient-evoked otoacoustic emission (TEOAE) suppression test method and stimulus–noise parameters that have a standard procedure and will enable the efferent system to be easily evaluated in clinics.
Research Design
This study was conducted in two parts with two different groups of participants as a within-subjects design. In the first part, the signal-to-noise ratio at which maximum suppression obtained was investigated with 29 participants. In the second part, the optimal contralateral noise presentation method (in terms of noise-time or noise-sweep) was examined with 21 participants.
Study Sample
In the first part 29 young adults aged between 18 and 32 (23.03 ± 2.84), 20 females and 9 males, and in the second part 21 young adults aged between 19 and 34 years (mean age: 23.71 ± 3.48 years), 16 females and 5 males, participated in the second part. All participants had normal hearing.
Data Collection and Analysis
To obtain maximum OAE suppression, different parameters were tested with the Otodynamics ILO292-II OAE device at both parts of the study in a double-walled audiometric test booths. Multirepeated analysis of variance, pairwise comparison, Friedman test, and Wilcoxon signed-rank tests were used for statistical analysis.
Results In the first part, maximum suppression was achieved at 65 dB peSPL (decibel peak-equivalent sound pressure level) TEOAE stimulus and 65 dB SPL broadband noise. In the second part, maximum suppression was obtained in noise-time method with 30 seconds “duration.”
Conclusions
To provide standardization in clinics, it can be recommended that the contralateral suppression of OAEs was measured at 65 dB peSPL TEOAE stimulus and 65 dB SPL broadband noise in the linear stimulation mode with Otodynamics ILO 292-II double-probe OAE device. To obtain maximum suppression, the noise-time method with 30 seconds duration can be used.DOI : 10.1055/s-0041-1735523|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?urlhttps://medone-comsci.thieme.com/ejourna [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=297134

Titre : Burnout in U.S. Audiologists Type de document : Article Auteurs : Diana C. Emanuel ; Nicholas S. Reed ; Madison Zimmer Année de publication : 2022 Article en page(s) : p. 36-44 Note générale : DOI: 10.1055/s-0041-1735253 Langues : Anglais (eng) Descripteurs : HE Vinci
Audiologues ; Condition de travail ; Epuisement professionnel ; Maslash Burnout Inventory (MBI) ; Stress professionnelRésumé : Background
Research on burnout in audiologists is limited, especially in the United States. Recent changes to the profession may have increased burnout.
Purpose
The purpose was to investigate burnout in the U.S. audiologists in diverse work settings.
Research Design
This study used three surveys: demographics/workplace stressors, Maslach Burnout Inventory (MBI), and professional quality of life (ProQOL).
Study Sample
Participants were 149 U.S. audiologists. Participants were diverse regarding experience, work setting, and location.
Data Collection and Analysis
The first survey provided demographics, perspectives on over-the-counter (OTC) hearing aids, stressors, and stress rating. The MBI assessed three dimensions of burnout: emotional exhaustion, depersonalization, and personal accomplishment. The ProQOL assessed burnout, compassion fatigue, and compassion satisfaction. Analyses included descriptive and inferential statistics of quantitative data and thematic analysis of qualitative data.
Results
Audiologists had low burnout, low compassion fatigue, and high compassion satisfaction. Experience was not related to stress rating; however, more experienced audiologists had greater compassion satisfaction and lower burnout, emotional exhaustion, and depersonalization compared with less experienced audiologists. Concern about OTC hearing aids was associated with stress rating. Thematic analysis identified 11 stressors, with 50% of stressors classified under work duties, time, and patients.
Conclusion
The U.S. audiologists had low burnout rates. Burnout was greatest in less experienced audiologists. Stress was not related to experience. Stressors included insufficient time to see patients, heavy caseload, time-consuming administrative tasks, pressure to sell hearing aids, and stressful interpersonal communication.DOI : 10.1055/s-0041-1735253|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=297138

Titre : Ambient Noise Monitoring during Pure-Tone Audiometry Type de document : Article Auteurs : George L. Saly ; Richard H. Wilson ; Robert H. Margolis Année de publication : 2022 Article en page(s) : p. 45-55 Note générale : DOI: 10.1055/s-0041-1735803 Langues : Anglais (eng) Descripteurs : HE Vinci
Audiométrie tonale ; Bruit ambiant ; DistractionMots-clés : Écouteur circum-auriculaire Écouteur supra-auriculaire Résumé : Background
There is an increasing need to administer hearing tests outside of sound-attenuating rooms. Maximum permissible ambient noise levels (MPANLs) from published in standards (Occupational Health and Safety Administration [OSHA] 1983; American National Standards Institute [ANSI] S3.1–1999 (R2018)) can be modified to account for the additional attenuation provided by circumaural earphones (relative to supra-aural earphones) that are used for pure-tone audiometry. Ambient noise can influence the results of pure-tone audiometry by elevating thresholds by direct masking and by producing distractions that affect the accuracy of the test. The effects of these distractions have not been studied in relation to pure-tone audiometry in adult listeners.
Purpose
In Part I MPANLs provided by ANSI and OSHA standards are extended to account for the greater attenuation provided by circumaural earphones. Rules (“alerts”) were developed taking into account the listeners' thresholds. In Part II effects of distracting noise on pure-tone thresholds are reported.
Methods and Results
In Part I MPANLs two standards were modified for circumaural earphones by adding the additional attenuation provided by three circumaural earphones (relative to supra-aural earphones). A set of rules (“alerts”) is provided for identifying masking effects from ambient noise in a variety of conditions (earphone type, threshold elevation, uncovered ear). In Part II the distracting effects of an industrial noise sample on thresholds obtained from five listeners with normal hearing are described. Pure-tone thresholds were measured in quiet and in distracting noise presented at various levels. The effects of the distracting noise on the following variables were measured: time per trial, number of trials required to measure threshold, threshold shift, and perceived distractibility of the noise. Time per trial was unaffected by distracting noise. Number of trials required for threshold, threshold shift, and perceived distractibility increased with distracting noise level.
Conclusion
Part I: The modified MPANLs provide more relevant determinations of the potential effects of ambient noise on pure-tone thresholds than the values in the standards. Part II: Distracting noise affects pure-tone threshold measurements in a manner that is different from direct masking. The potential contaminating effect of distracting noise can be measured and reported.DOI : 10.1055/s-0041-1735803|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=297140

Études par échantillonnage ; Évaluation de résultat (soins) ; Implants cochléaires ; Marqueurs biologiques ; MicroARN ; PérilympheRésumé : Hypothesis
MicroRNA (miRNA) expression profiles from human perilymph correlate to post cochlear implantation (CI) hearing outcomes.
Background
The high inter-individual variability in speech perception among cochlear implant recipients is still poorly understood. MiRNA expression in perilymph can be used to characterize the molecular processes underlying inner ear disease and to predict performance with a cochlear implant.
Methods
Perilymph collected during CI from 17 patients was analyzed using microarrays. MiRNAs were identified and multivariable analysis using consonant-nucleus-consonant testing at 6 and 18 months post implant activation was performed. Variables analyzed included age, gender, preoperative pure tone average (PTA), and preoperative speech discrimination (word recognition [WR]). Gene ontology analysis was performed to identify potential functional implications of changes in the identified miRNAs.
Results
Distinct miRNA profiles correlated to preoperative PTA and WR. Patients classified as poor performers showed downregulation of six miRNAs that potentially regulate pathways related to neuronal function and cell survival.
Conclusion
Individual miRNA profiles can be identified in microvolumes of perilymph. Distinct non-coding RNA expression profiles correlate to preoperative hearing and postoperative cochlear implant outcomes.DOI : 10.1055/s-0041-1742234|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=294828

Cellules souches ; Organoïdes ; Perte d'audition ; Surdité neurosensorielle (SNHL)Mots-clés : Cellules sensorielles otiques Résumé : Background
Sensorineural hearing loss (SNHL) is a significant cause of morbidity worldwide and currently has no curative treatment. Technological advancements in stem cell therapy have led to numerous studies that examine the generation of otic sensory cells from progenitors to restore inner ear function. Recently, organoids have emerged as a promising technique to further advance the process of creating functional replacement cells after irreversible hearing loss. Organoids are the three-dimensional generation of stem cells in culture to model the tissue organization and cellular components of the inner ear. Organoids have emerged as a promising technique to create functioning cochlear structures in vitro and may provide crucial information for the utilization of stem cells to restore SNHL.
Purpose
The purpose of this review is to discuss the recent advancements in stem cell-based regenerative therapy for SNHL.
Results
Recent studies have improved our understanding about the developmental pathways involved in the generation of hair cells and spiral ganglion neurons. However, significant challenges remain in elucidating the molecular interactions and interplay required for stem cells to differentiate and function as otic sensory cells. A few of the challenges encountered with traditional stem cell therapy may be addressed with organoids.
Conclusion
Stem cell-based regenerative therapy holds a great potential for developing novel treatment modalities for SNHL. Further advancements are needed in addressing the challenges associated with stem cell-based regenerative therapy and promote their translation from bench to bedside.DOI : 10.1055/s-0041-1728677|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=295128

Dépistage génétique ; Oreille interne ; Perte d'audition ; Thérapie génétiqueRésumé : Millions of people worldwide have disabling hearing loss because one of their genes generates an incorrect version of some specific protein the ear requires for hearing. In many of these cases, delivering the correct version of the gene to a specific target cell within the inner ear has the potential to restore cochlear function to enable high-acuity physiologic hearing. Purpose: In this review, we outline our strategy for the development of genetic medicines with the potential to treat hearing loss. We will use the example of otoferlin gene (OTOF)-mediated hearing loss, a sensorineural hearing loss due to autosomal recessive mutations of the OTOF gene.

Cellules ciliées auditives ; Implants cochléaires ; Perte d'audition ; Régénération ; Surdité neurosensorielle (SNHL)Résumé : Damage to auditory hair cells is a key feature of sensorineural hearing loss due to aging, noise exposure, or ototoxic drugs. Though hair-cell loss is permanent in humans, research in bird species led to the discovery that analogous hair cells of the avian basilar papilla are able to regenerate after being damaged by ototoxic agents. Regeneration appears to occur through a combination of the mitotic expansion of a precursor population of supporting cells and direct transdifferentiation of supporting cells into functioning hair cells. This review will synthesize the relevant anatomy and pathophysiology of sensorineural hearing loss, the historical observations that led to the genesis of the hair-cell regeneration field, and perspectives on initial human hair-cell regeneration trials.

Cellules ciliées auditives ; Perte d'audition ; Régénération ; Surdité neurosensorielle (SNHL) ; ThérapeutiqueRésumé : Sensorineural hearing loss (SNHL) is typically a permanent and often progressive condition that is commonly attributed to sensory cell loss. All vertebrates except mammals can regenerate lost sensory cells. Thus, SNHL is currently only treated with hearing aids or cochlear implants. There has been extensive research to understand how regeneration occurs in nonmammals, how hair cells form during development, and what limits regeneration in maturing mammals. These studies motivated efforts to identify therapeutic interventions to regenerate hair cells as a treatment for hearing loss, with a focus on targeting supporting cells to form new sensory hair cells. The approaches include gene therapy and small molecule delivery to the inner ear. At the time of this publication, early-stage clinical trials have been conducted to test targets that have shown evidence of regenerating sensory hair cells in preclinical models. As these potential treatments move closer to a clinical reality, it will be important to understand which therapeutic option is most appropriate for a given population. It is also important to consider which audiological tests should be administered to identify hearing improvement while considering the pharmacokinetics and mechanism of a given approach. Some impacts on audiological practice could include implementing less common audiological measures as standard procedure. As devices are not capable of repairing the damaged underlying biology, hair-cell regeneration treatments could allow patients to benefit more from their devices, move from a cochlear implant candidate to a hearing aid candidate, or move a subject to not needing an assistive device. Here, we describe the background, current state, and future implications of hair-cell regeneration research.

Emissions otoacoustiques évoquées (OEA)(OAE) ; Essais cliniques comme sujet ; Littérature de revue comme sujet ; Médicaments en essais cliniques ; Ototoxicité ; Surdité due au bruit ; Surdité neurosensorielle (SNHL)Résumé : Background
The previous 30 years have provided information on the mechanisms of cell death in the inner ear after noise exposure, ototoxic drug injury, and during aging, and clinical trials have emerged for all of these acquired forms of hearing loss. Sudden hearing loss is less well understood, but restoration of hearing after sudden hearing loss is also a long-standing drug target, typically using steroids as an intervention but with other agents of interest as well.
Purpose
The purpose of this review was to describe the state of the science regarding clinical testing of investigational medicinal products for the inner ear with respect to treatment or prevention of acquired hearing loss.
Data Collection and Analysis
Comprehensive search and summary of clinical trials listed in the National Library of Medicine (www.ClinicalTrials.gov) database identified 61 clinical trials.
Results
Study phase, status, intervention, and primary, secondary, and other outcomes are summarized for studies assessing prevention of noise-induced hearing loss, prevention of drug-induced hearing loss, treatment of stable sensorineural hearing loss, and treatment of sudden sensorineural hearing loss.

Titre : The Frequency Characteristic of Silicone Domes in Receiver in the Canal Hearing Aids Type de document : Article Auteurs : Masafumi Ueno ; Seiichi Shinden ; Daisuke Suzuki ; Noriomi Suzuki ; Takanori Nishiyama ; Naoki Oishi ; Kaoru Ogawa Année de publication : 2021 Article en page(s) : p. 556-561 Note générale : DOI: 10.1055/s-0041-1732439 Langues : Anglais (eng) Descripteurs : HE Vinci
Aides auditives ; Conduit auditif externe (CAE) ; Ecouteur déporté ; GAIN PROTHETIQUE ; Silicone ; VentilationRésumé : Background
There are several types of silicone domes in receiver in the canal hearing aids (RICs), which have different occlusion levels. However, the frequency characteristics of each type of silicone dome are unclear.
Purpose
This study aimed to determine the frequency characteristics of three types of silicone domes (open domes, double-type power domes, and tulip domes) in RICs.
Research Design
This is an interventional study.
Study Sample
In total, 11 participants with a normal sense of hearing were prospectively enrolled.
Intervention
Participants were fitted with hearing aids, which were adjusted to similar settings, and only the silicone domes were changed. The acoustic gain of hearing aids was adjusted to 20 dB in the range of 250 Hz to 4 kHz using the 2-cc coupler.
Data Collection and Analysis
We measured the real-ear aided gain (REAG) for each type of silicone dome. In each frequency, we statistically compared the REAG of each type of dome. Acoustic gain using the Open Fit coupler of each type of dome was also measured.
Results
The REAG was obtained with no leakage with open domes only at 2 kHz, and with tulip domes and double-type power domes in the range of 1 to 2 kHz. Double-type power domes obtained significantly higher REAG than tulip domes at 250 and 500 Hz. Under the Open Fit coupler, all types obtained higher acoustic gain than the REAG.
Conclusion
This study provides the analysis of the frequency characteristics of silicone domes in RICs. The highest degree of occlusion was observed in double-type power domes, followed by tulip domes, and the lowest was observed in open domes.DOI : 10.1055/s-0041-1732439|1 Disponible en ligne : Oui En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=291821

Titre : Self-Reported Tinnitus Severity Prior to and During the COVID-19 Lockdown in the United Kingdom Type de document : Article Auteurs : Hashir Aazh ; Ali A. Danesh ; Brian C. J. Moore Année de publication : 2021 Article en page(s) : p. 562-566 Langues : Anglais (eng) Descripteurs : HE Vinci
Acouphène ; Audiologie ; COVID-19 ; Politique de confinement de la populationRésumé : Background and Purpose The aim of this study was to assess whether the severity of tinnitus, as measured using ratings of tinnitus loudness, annoyance, and effect on life, was influenced by the lockdown related to the coronavirus disease 2019 (COVID-19) pandemic.
Research Design This was a retrospective study.
Study Sample The data for 105 consecutive patients who were seen at a tinnitus clinic in an audiology department in the United Kingdom during the COVID-19 lockdown between April and June 2020 and 123 patients seen in the same period of the previous year, prior to the COVID-19 pandemic were included.
Data Collection Demographic data for the patients, results of their pure-tone audiometry, and their score on visual analog scale (VAS) of tinnitus loudness, annoyance, and effect on life were imported from their records held at the audiology department. This was a retrospective survey comparing ratings on the VAS of tinnitus loudness, annoyance, and effect on life for consecutive patients seen during the COVID-19 lockdown and consecutive patients seen in the same period of the previous year, prior to the COVID-19 pandemic. Patients seen prior to lockdown used a pen and paper version of the VAS, while the patients who were assessed during the COVID-19 lockdown used an adapted version of the VAS, via telephone. All patients were seeking help for their tinnitus for the first time.
Results The mean scores for tinnitus loudness, annoyance, and effect on life did not differ significantly for the groups seen prior to and during lockdown.
Conclusion Any changes in psychological well-being or stress produced by the lockdown did not significantly affect ratings of the severity of tinnitus.DOI : 10.1055/s-0041-1731733|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=291822

Titre : Vestibular Evoked Myogenic Potentials and Postural Control in Adults with Age-Related Hearing Loss Type de document : Article Auteurs : Steven M. Doettl ; Patrick N. Plyler ; Devin L. McCaslin ; Larissa G. Conolly ; Jesus D. Gomez Année de publication : 2021 Article en page(s) : p. 567-575 Note générale : DOI: 10.1055/s-0041-1735521 Langues : Anglais (eng) Descripteurs : HE Vinci
Déficience auditive liée à l'âge (ARHL) ; Examen vestibulaire ; Potentiels évoqués vestibulaires myogéniques (cVEMP) (mVEMP) (oVEMP) ; PresbyacousieRésumé : Background Age-related changes to auditory function have been attributed to, through histopathological study, specific degradation of the sensory, supporting, and afferent structures of the cochlea. Similar to age-related hearing loss (ARHL), age-related changes to the vestibular sensory and supporting structures with specific degeneration of the saccule, utricle, otoconia, primary vestibular afferents have also been noted. Significant decreases in postural control with age are also well-documented in the literature attributed to multifactorial changes in function.
Purpose The purpose of this study is to further evaluate the association of ARHL and saccule/utricle function as measured by VEMPs and postural control measures.
Study Sample Audiologic, vestibular and postural control results from 34 participants were analyzed. The age range was from 50 to 70 years old with 16 males and 18 females. Group 1 consisted of 33 ears from participants age 50–70 with normal hearing with average age of 60.8 years (sd 6.287 years) and an average speech-frequency PTA of 14.8 dB HL. Group 2 consisted of 27 ears from participants age 50–70 years with ARHL and an average age of 62.9 years (sd 4.984 years) with an average speech-frequency PTA of 39.9 dB HL.
Data Collection and Analysis Independent samples t-tests were used to assess group mean differences for dependent variables. The independent variable was group with 2 levels (normal hearing, ARHL). The dependent variables were cVEMP P1/N1 Amplitude, cVEMP P1 Latency, cVEMP N1 Latency, cVEMP P2 Latency, oVEMP N1/P1 Amplitude, oVEMP N1 Latency, and oVEMP P1 Latency. Additional analyses were completed using Pearson correlation to evaluate the relationship of audiometric findings to the dependent variables.
Results Results indicated significantly decreased cVEMP P1/N1 amplitude and oVEMP N1/P1 amplitude adults 50–70-years of age with ARHL compared with their normal counterparts. Significant correlations were also found for audiometric results and both cVEMP and oVEMP measures.
Conclusions Overall, the results of this study describe concomitant auditory and vestibular degeneration as measured by audiometric testing and vestibular function testing involving the saccule and to a lesser degree the utricle.DOI : 10.1055/s-0041-1735521|1 Disponible en ligne : Oui En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=291824

Audiométrie électroencéphalographique ; Potentiel évoqué auditif (PEA) ; Potentiels évoqués auditifs du tronc cérébral (ABR) ; Pression sanguineRésumé : Background
Numerous cardiometabolic factors may underlie risk of hearing loss. Modifiable risk factors such as non-optimal blood pressure (BP) are of interest.
Purpose
To investigate early auditory evoked potentials (AEPs) in persons with nonoptimal BP.
Research Design
A cross-sectional nonexperimental study was performed.
Study Sample
Fifty-two adults (18–55 years) served as subjects. Individuals were classified as having optimal (systolic [S] BP
Data Collection and Analysis
Behavioral thresholds from 0.25 to 16 kHz were collected. Threshold auditory brain stem responses (ABRs) were recorded using rarefaction clicks (17.7/second) from 80 dB nHL to wave V threshold. Electrocochleograms were obtained with 90 dB nHL 7.1/second alternating clicks and assessed for summating and compound action potentials (APs). Outcomes were compared via independent samples t tests. Linear mixed effects models for behavioral thresholds and ABR wave latencies were constructed to account for potential confounders.
Results
Wave I and III latencies were comparable between optimal and non-optimal BP groups. Wave I was prolonged in hypertensive versus optimal BP subjects at stimulus level 70 dB nHL (p = 0.016). ABR wave V latencies were prolonged in non-optimal BP at stimulus level 80 dB nHL (p = 0.048) and in HTN at levels of 80, 50, and 30 dB nHL (all p
Conclusion
Elevated BP and more specifically, HTN was associated with subtle AEP abnormalities. This study provides preliminary evidence that nonoptimal BP, and more specifically HTN, may be related to auditory neural dysfunction; larger confirmatory studies are warranted.DOI : 10.1055/s-0041-1733970|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=291825

Membrane des statoconies ; Potentiel évoqué stationnaire (ASSR) ; Potentiels évoqués vestibulaires myogéniques (cVEMP) (mVEMP) (oVEMP)Résumé : Background
Traditional approaches to cervical vestibular-evoked myogenic potentials use a transient stimulus to elicit an onset response. However, alternate approaches with long duration stimuli may allow the development of new methodologies to better understand basic function of the vestibular system, as well as potentially developing new clinical applications.
Purpose
The objective of this study was to examine the effects of stimulus polarity on response properties of amplitude-modulated cervical vestibular-evoked myogenic potentials (AMcVEMPs).
Research Design
Prospective, repeated-measures, within-subjects design.
Study Sample
Participants were 16 young, healthy adults (ages 21–38 years).
Data Collection and Analysis
Amplitude-modulated tones, with carrier frequency of 500 Hz and modulation frequency of 37 Hz, were used to elicit AMcVEMPs. Responses were analyzed in three different stimulus polarity conditions: condensation, rarefaction, and alternating. The resulting data were analyzed for differences across polarity conditions.
Results
AMcVEMP amplitudes, both raw and corrected for tonic muscle activation, were equivalent across the different stimulus phase conditions. In addition, response signal-to-noise ratio and phase coherence were equivalent across the different phases of the stimulus.
Conclusion
Analyses of AMcVEMPs are stable when the carrier frequency starting phase is altered and the phase of the temporal envelope is constant.DOI : 10.1055/s-0041-1733968|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=291829

Titre : Audibility and Spectral-Ripple Discrimination Thresholds as Predictors of Word Recognition with Nonlinear Frequency Compression Type de document : Article Auteurs : Marc A. Brennan ; Ryan W.

Resolution spectraleRésumé : Background
Nonlinear frequency compression (NFC) lowers high-frequency sounds to a lower frequency and is used to improve high-frequency audibility. However, the efficacy of NFC varies widely—while some individuals benefit from NFC, many do not. Spectral resolution is one factor that might explain individual benefit from NFC. Because individuals with better spectral resolution understand more speech than those with poorer spectral resolution, it was hypothesized that individual benefit from NFC could be predicted from the change in spectral resolution measured with NFC relative to a condition without NFC.
Purpose
This study aimed to determine the impact of NFC on access to spectral information and whether these changes predict individual benefit from NFC for adults with sensorineural hearing loss (SNHL).
Research Design
Present study is a quasi-experimental cohort study. Participants used a pair of hearing aids set to the Desired Sensation Level algorithm (DSL m[i/o]).
Study Sample
Participants were 19 adults with SNHL, recruited from the Boys Town National Research Hospital Participant Registry.
Data Collection and Analysis
Participants were seated in a sound-attenuating booth and then percent-correct recognition of words, and spectral-ripple discrimination thresholds were measured for two different conditions, with and without NFC. Because audibility is known to influence spectral-ripple thresholds and benefit from NFC, audibility was quantified using the aided speech intelligibility index (SII). Linear mixed models were generated to predict word recognition using the aided SII and spectral-ripple discrimination thresholds.
Results
While NFC did not influence percent-correct word recognition, participants with higher (better) aided SII and spectral-ripple discrimination thresholds understood more words than those with either a lower aided SII or spectral-ripple discrimination threshold. Benefit from NFC was not predictable from a participant's aided SII or spectral-ripple discrimination threshold.
Conclusion
We have extended previous work on the effect of audibility on benefit from NFC to include a measure of spectral resolution, the spectral-ripple discrimination threshold. Clinically, these results suggest that patients with better audibility and spectral resolution will understand speech better than those with poorer audibility or spectral resolution; however, these results are inconsistent with the notion that individual benefit from NFC is predictable from aided audibility or spectral resolution.DOI : 10.1055/s-0041-1732333|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=291835

Titre : Automated Forced-Choice Tests of Speech Recognition Type de document : Article Auteurs : Robert H. Margolis ; Richard H. Wilson ; George L. Saly ; Heather M. Gregoire ; Brandon M. Madsen Année de publication : 2021 Article en page(s) : p. 606-615 Note générale : DOI: 10.1055/s-0041-1733964 Langues : Anglais (eng) Descripteurs : HE Vinci
Choix forcé ; Reconnaissance de la parole ; Seuil minimum de stimulation (THR)Résumé : Purpose
This project was undertaken to develop automated tests of speech recognition, including speech-recognition threshold (SRT) and word-recognition test, using forced-choice responses and computerized scoring of responses. Specific aims were (1) to develop an automated method for measuring SRT for spondaic words that produces scores that are in close agreement with average pure-tone thresholds and (2) to develop an automated test of word recognition that distinguishes listeners with normal hearing from those with sensorineural hearing loss and which informs the hearing aid evaluation process.
Method
An automated SRT protocol was designed to converge on the lowest level at which the listener responds correctly to two out of two spondees presented monaurally. A word-recognition test was conducted with monosyllabic words (female speaker) presented monaurally at a fixed level. For each word, there were three rhyming foils, displayed on a touchscreen with the test word. The listeners touched the word they thought they heard. Participants were young listeners with normal hearing and listeners with sensorineural hearing loss. Words were also presented with nonrhyming foils and in an open-set paradigm. The open-set responses were scored by a graduate student research assistant.
Results
The SRT results agreed closely with the pure-tone average (PTA) obtained by automated audiometry. The agreement was similar to results obtained with the conventional SRT scoring method. Word-recognition scores were highest for the closed-set, nonrhyming lists and lowest for open-set responses. For the hearing loss participants, the scores varied widely. There was a moderate correlation between word-recognition scores and pure-tone thresholds which increased as more high frequencies were brought into the PTA. Based on the findings of this study, a clinical protocol was designed that determines if a listener's performance was in the normal range and if the listener benefited from increasing the level of the stimuli.
Conclusion
SRTs obtained using the automated procedure are comparable to the results obtained by the conventional clinical method that is in common use. The automated closed-set word-recognition test results show clear differentiation between scores for the normal and hearing loss groups. These procedures provide clinical test results that are not dependent on the availability of an audiologist to perform the tests.DOI : 10.1055/s-0041-1733964|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=291837

Titre : Evaluation of Automatic Directional Processing with Cochlear Implant Recipients Type de document : Article Auteurs : Lisa G. Potts ; Soo Jang ; Cory L. Hillis Année de publication : 2021 Article en page(s) : p. 478-486 Langues : Anglais (eng) Descripteurs : HE Vinci
Implants cochléaires ; Microphone directionnel ; Perception de la paroleRésumé : Background
For cochlear implant (CI) recipients, speech recognition in noise is consistently poorer compared with recognition in quiet. Directional processing improves performance in noise and can be automatically activated based on acoustic scene analysis. The use of adaptive directionality with CI recipients is new and has not been investigated thoroughly, especially utilizing the recipients' preferred everyday signal processing, dynamic range, and/or noise reduction.
Purpose
This study utilized CI recipients' preferred everyday signal processing to evaluate four directional microphone options in a noisy environment to determine which option provides the best speech recognition in noise. A greater understanding of automatic directionality could ultimately improve CI recipients' speech-in-noise performance and better guide clinicians in programming.
Study Sample
Twenty-six unilateral and seven bilateral CI recipients with a mean age of 66 years and approximately 4 years of CI experience were included.
Data Collection and Analysis
Speech-in-noise performance was measured using eight loudspeakers in a 360-degree array with HINT sentences presented in restaurant noise. Four directional options were evaluated (automatic [SCAN], adaptive [Beam], fixed [Zoom], and Omni-directional) with participants' everyday use signal processing options active. A mixed-model analysis of variance (ANOVA) and pairwise comparisons were performed.
Results
Automatic directionality (SCAN) resulted in the best speech-in-noise performance, although not significantly better than Beam. Omni-directional performance was significantly poorer compared with the three other directional options. A varied number of participants performed their best with each of the four-directional options, with 16 performing best with automatic directionality. The majority of participants did not perform best with their everyday directional option.
Conclusion
The individual variability seen in this study suggests that CI recipients try with different directional options to find their ideal program. However, based on a CI recipient's motivation to try different programs, automatic directionality is an appropriate everyday processing option.Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=288587

Titre : Live Evaluation of Auditory Preference, a Laboratory Test for Evaluating Auditory Preference Type de document : Article Auteurs : Karolina Smeds ; Josefina Larsson ; Martin Dahlquist ; Florian Wolters ; Petra Wolters Année de publication : 2021 Article en page(s) : p. 487-500 Langues : Anglais (eng) Descripteurs : HE Vinci
Aides auditives ; Analyse appariée ; Évaluation écologique instantanéeMots-clés : Test de scénario Résumé : Background
Many laboratory tests are performed under unrealistic conditions. Tasks, such as repeating words or sentences, are performed in simple loudspeaker setups. Currently, many research groups focus on realistic audiovisual laboratory setups. Fewer groups focus on the tasks performed during testing.
Purpose
A semicontrolled laboratory test method focusing on the tasks performed, the Live Evaluation of Auditory Preference (LEAP) was evaluated. LEAP is developed to evaluate hearing-instrument performance in test scenarios that represent everyday listening situations.
Research Design
LEAP was evaluated in a feasibility study. The method comprises conversations between a test participant and one or two test leaders, enabling evaluation of the test participant's own voice. The method allows for visual cues (when relevant) and introduce social pressure to participate in the conversation. In addition, other everyday listening tasks, such as watching television (TV) and listening to radio, are included. In this study, LEAP was used to assess preference for two hearing aid settings using paired comparisons.
Study Sample
Nineteen experienced hearing aid users (13 females and 6 males; mean age 74 years), participated in the study.
Data Collection and Analysis
LEAP was performed at three visits to the laboratory. In addition, participants conducted a field trial where the two hearing aid programs were compared using Ecological Momentary Assessments (EMA). During LEAP testing, six mandatory test cases were used, representing commonly occurring everyday listening situations. Individual test cases were also included, selected from individually experienced listening situations during the field trial. Within- and between-session reliability of the LEAP test was investigated. Validity was investigated by comparing the LEAP and the EMA results.
Results
For the current signal-processing evaluation, the test was judged to have acceptable reliability and validity. The inclusion of individually selected test cases increased the representativeness of the LEAP test, but it did not substantially alter the results in the current study.
Conclusion
LEAP in its current implementation seems suitable for investigating signal-processing preference in the laboratory in a way that is indicative of everyday preference. The LEAP method represents one step forward in bringing the real world into the laboratory.Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=288589

Acouphène ; Aides auditives ; Enquêtes et questionnaires ; Perte d'auditionRésumé : Background
There are many counseling and sound therapy approaches to treat tinnitus. Counseling approaches range from providing information using directive or collaborative approaches. Sound therapies include strategies that use background sounds to totally or partially mask tinnitus to reduce the prominence of or decrease the loudness or annoyance of the tinnitus.
Purpose
We evaluated the effectiveness of tinnitus activities treatment (TAT) in two groups, those without hearing aids (HA) and those who were provided with HA. In both groups, comparisons were made among those receiving (1) counseling only, (2) counseling and partial masking, and (3) counseling and total masking.
Research Design
Participants were provided with HA or not, based on their choice, and then randomly assigned to one of the three groups. The Tinnitus Handicap Questionnaire (THQ) was used as the primary measure.
Results
For those without HA, significant benefits were obtained for 8 out of 22 participants in the counseling group, 8 of 13 in the total masking group, and 8 of 24 in the partial mask group. The average decrease in the THQ was 15% for the counseling group, 25% for the total mask, and 14% for the partial masking group. For those with HA; significant benefits were obtained for 5 of 16 in the counseling group, 3 of 14 in the total mask group, and 6 of 13 in the partial mask group. The average decrease in the THQ score was 12% for counseling, 13% for total masking, and 16% for partial masking. No significant differences among groups were observed.
Conclusion
Individual differences were large. Many benefited from their treatment, but some did not. We believe this was likely influenced by their expectations.Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=288590

EquilibreRésumé : Background
Vestibular and/or balance deficits are well documented in deaf individuals. In the adult population, poor vestibular and/or balance function can lead to activity limitations and increased risk of falling. An effective case history by health care providers to probe for potential balance concerns is necessary for appropriate referral; however, patients may not consistently report vestibular and balance symptoms. Currently, there is little information available as to how deaf individuals report these symptoms and how their reported balance ability relates to measures of balance and vestibular functions.
Purpose
The aim of the current study was to evaluate self-perceived balance ability in participants who self-identify as either deaf or hearing, and compare these results to measures of balance and vestibular functions.
Research Design
This is a prospective, between-group design.
Study Sample
Data from 57 adults between the ages of 18 to 29 years who self-reported as deaf (39) or hearing (18) were evaluated. Participants completed the activities-specific balance confidence (ABC) scale, a brief case history, self-report rating of balance (SRRB), the Modified Clinical Test of Sensory Integration of Balance (mCTSIB), along with both ocular vestibular-evoked myogenic potentials (oVEMPs) and cervical vestibular-evoked myogenic potentials (cVEMPs). Only participants with SRRBs of good or excellent were included in the inferential analyses.
Results
Proportions of participants rating their balance ability as either good or excellent were similar between both groups, as were the results on the ABC scale. Statistical analyses revealed significant associations between the groups on both oVEMPs and cVEMPs. No significant differences were observed on sway velocities in any of the mCTSIB conditions; however, more than one-third of deaf participants had mCTSIB Condition 4—on foam, eyes closed—scores above 2 standard deviations of the hearing group.
Conclusion
Deaf participants self-report similar ratings of balance ability as hearing participants despite significant differences in vestibular function. A relatively large subset of deaf participants had increased sway velocity on balance function testing that required increased reliance on vestibular cues. A thorough discussion of balance and vestibular symptoms should be completed when a patient who self-identifies as deaf is seen by a health care provider so that appropriate screenings or referrals can be completed as necessary.Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=288591

Titre : Effects of the Configuration of Hearing Loss on Consonant Perception between Simulated Bimodal and Electric Acoustic Stimulation Hearing Type de document : Article Auteurs : Yang-Soo Yoon ; George Whitaker ; Yune S.

Perception des consonnesRésumé : Cochlear implant technology allows for acoustic and electric stimulations to be combined across ears (bimodal) and within the same ear (electric acoustic stimulation [EAS]). Mechanisms used to integrate speech acoustics may be different between the bimodal and EAS hearing, and the configurations of hearing loss might be an important factor for the integration. Thus, differentiating the effects of different configurations of hearing loss on bimodal or EAS benefit in speech perception (differences in performance with combined acoustic and electric stimulations from a better stimulation alone) is important.
Using acoustic simulation, we determined how consonant recognition was affected by different configurations of hearing loss in bimodal and EAS hearing.
Research Design
A mixed design was used with one between-subject variable (simulated bimodal group vs. simulated EAS group) and one within-subject variable (acoustic stimulation alone, electric stimulation alone, and combined acoustic and electric stimulations).
Study Sample
Twenty adult subjects (10 for each group) with normal hearing were recruited.
Data Collection and Analysis
Consonant perception was unilaterally or bilaterally measured in quiet. For the acoustic stimulation, four different simulations of hearing loss were created by band-pass filtering consonants with a fixed lower cutoff frequency of 100 Hz and each of the four upper cutoff frequencies of 250, 500, 750, and 1,000 Hz. For the electric stimulation, an eight-channel noise vocoder was used to generate a typical spectral mismatch by using fixed input (200–7,000 Hz) and output (1,000–7,000 Hz) frequency ranges. The effects of simulated hearing loss on consonant recognition were compared between the two groups.
Results
Significant bimodal and EAS benefits occurred regardless of the configurations of hearing loss and hearing technology (bimodal vs. EAS). Place information was better transmitted in EAS hearing than in bimodal hearing.
Conclusion
These results suggest that configurations of hearing loss are not a significant factor for integrating consonant information between acoustic and electric stimulations. The results also suggest that mechanisms used to integrate consonant information may be similar between bimodal and EAS hearing.Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=288593

Implants cochléaires ; Logiciel de reconnaissance de la paroleRésumé : Background
Recent models theorize that neurocognitive resources are deployed differently during speech recognition depending on task demands, such as the severity of degradation of the signal or modality (auditory vs. audiovisual [AV]). This concept is particularly relevant to the adult cochlear implant (CI) population, considering the large amount of variability among CI users in their spectro-temporal processing abilities. However, disentangling the effects of individual differences in spectro-temporal processing and neurocognitive skills on speech recognition in clinical populations of adult CI users is challenging. Thus, this study investigated the relationship between neurocognitive functions and recognition of spectrally degraded speech in a group of young adult normal-hearing (NH) listeners.
Purpose
The aim of this study was to manipulate the degree of spectral degradation and modality of speech presented to young adult NH listeners to determine whether deployment of neurocognitive skills would be affected.
Research Design
Correlational study design.
Study Sample
Twenty-one NH college students.
Data Collection and Analysis
Participants listened to sentences in three spectral-degradation conditions: no degradation (clear sentences); moderate degradation (8-channel noise-vocoded); and high degradation (4-channel noise-vocoded). Thirty sentences were presented in an auditory-only (A-only) modality and an AV fashion. Visual assessments from The National Institute of Health Toolbox Cognitive Battery were completed to evaluate working memory, inhibition-concentration, cognitive flexibility, and processing speed. Analyses of variance compared speech recognition performance among spectral degradation condition and modality. Bivariate correlation analyses were performed among speech recognition performance and the neurocognitive skills in the various test conditions.
Results
Main effects on sentence recognition were found for degree of degradation (p =
Conclusions
Inhibition-concentration skills are deployed differentially during sentence recognition, depending on the level of signal degradation. Additional studies will be required to study these relations in actual clinical populations such as adult CI users.Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=288594

Aides auditives ; Comparaison ; Comportement du consommateur ; Evaluation de l'aide auditive ; Préférence des patientsRésumé : Background
Modern hearing aids have various features and functionalities, such as digital wireless streaming, bilateral connectivity, rechargeability, and specialized programs, which allow for a multitude of hearing aid attributes (e.g., comfort, reliability, and clarity). Consumers likely vary greatly in their preferences for these hearing aid attributes. Their preferences might be related to various demographic and hearing loss characteristics.
Purpose
The purposes of this study were to describe which hearing aid attributes consumers find desirable when choosing their hearing aids and to explore factors that might predict preferences.
Research Design
Cross-sectional.
Intervention
Not applicable.
Data Collection and Analysis
In this retrospective study, hearing aid attribute preferences were evaluated from consumers who answered questions in the Help Me Choose tool on the HearingTracker.com Web site. Chi-squared tests and correlation analyses were used to identify potential relationships between attribute preference and respondent characteristics. Cluster analysis with Partitioning Around Medoids (PAM) was used to identify patterns of attribute preferences.
Results
Of the 21 hearing aid attributes queried, the four most favorably rated were improved ability to hear friends and family in quiet and in noisy settings, physical comfort, and reliability, with 75 to 88% of respondents rating these attributes as very or extremely important. Type of hearing loss, technology level preference, and mobile phone brand were significantly associated with preferences for all 21 hearing aid attributes. PAM cluster analysis unveiled two unique user groups based on their preference to hearing aid attributes. One-third of the respondents preferred high-end technology and favored all types of advanced attributes. The other two-thirds of users predominantly preferred either advanced or best match and were more selective about which attributes were most important to them.
Conclusion
Patterns in preferences to hearing aid attributes help identify unique subgroups of consumers.

Mot monosyllabiqueRésumé : Background
Speech audiometry materials are widely available in many different languages. However, there are no known standardized materials for the assessment of speech recognition in Arabic-speaking children.
Purpose
The aim of the study was to develop and validate phonetically balanced and psychometrically equivalent monosyllabic word recognition lists for children through a picture identification task.
Research Design
A prospective repeated-measure design was used. Monosyllabic words were chosen from children's storybooks and were evaluated for familiarity. The selected words were then divided into four phonetically balanced word lists. The final lists were evaluated for homogeneity and equivalency.
Study Sample
Ten adults and 32 children with normal hearing sensitivity were recruited.
Data Collection and Analyses
Lists were presented to adult subjects in 5 dB increment from 0 to 60 dB hearing level. Individual data were then fitted using a sigmoid function from which the 50% threshold, slopes at the 50% points, and slopes at the 20 to 80% points were derived to determine list psychometric properties. Lists were next presented to children in two separate sessions to assess their equivalency, validity, and reliability. Data were subjected to a mixed design analysis of variance.
Results
No statistically significant difference was found among the word lists.
Conclusion
This study provided an evidence that the monosyllabic word lists had comparable psychometric characteristics and reliability. This supports that the constructed speech corpus is a valid tool that can be used in assessing speech recognition in Arabic-speaking children.Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=288596

Titre : Differences in Force Levels, Word Recognition in Quiet, Sentence Reception Threshold in Noise, and Subjective Outcomes for a Bone-Anchored Hearing Device Programmed Using Manufacturer First-Fit, Aided Sound-Field Thresholds and Programmed to DSL-BCD Using a Skull Simulator Type de document : Article Auteurs : Adam Voss ; Alison Brockmeyer ; Michael Valente ; John Pumford ; Cameron C. Wick ; Nedim Durakovic Année de publication : 2021 Article en page(s) : p. 395-404 Note générale : DOI: 10.1055/s-0041-1730412 Langues : Anglais (eng) Descripteurs : HE Vinci
Aides auditives ; Desired sensation level (DSL) ; Prothèse auditive à ancrage osseux (BAHA)Mots-clés : Baha Power 5 Simulateur à crâne Résumé : Background
Best practice guidelines for verifying fittings of bone-anchored hearing devices (BAHD) recommend using aided sound-field thresholds (ASFT), but express caution regarding the variables impacting obtaining valid and reliable ASFTs.[1] Recently, a skull simulator was introduced to facilitate programming BAHD devices in force level (FL) to desired sensation level-bone conduction devices (skull simulator/DSL-BCD)[2] [3] targets in a hearing aid analyzer. Currently, no evidence is available reporting if differences in measured FL using the manufacturer first-fit (FF) and word recognition in quiet, sentence reception threshold in noise, and subjective outcomes are present for a BAHD programmed using ASFT versus programmed using skull simulator/DSL-BCD targets.
Purpose
The aim of this study was to examine if significant differences were present in FL using the FF and word recognition in quiet at 50 and 65 decibel of sound pressure level (dB SPL), sentence reception threshold in noise and subjective outcomes using the abbreviated profile of hearing aid benefit (APHAB), and speech, spatial, and qualities of hearing (SSQ) between a BAHD fit using ASFT or skull simulator/DSL-BCD targets.
Research Design
A double-blind randomized crossover design with 15 adults having unilateral sensorineural hearing loss. All participants were successful users of the Cochlear America Baha 5.
Data Collection and Analysis
Baha Power 5 devices were fit using FF, ASFT, and skull simulator/DSL-BCD targets. Order of the three fitting strategies was randomly assigned and counter-balanced.
Results
No significant differences were found for a BAHD device programmed using ASFT versus skull simulator/DSL-BCD targets for consonant-nucleus-consonant words in quiet at 50 or 65 dB SPL, sentence reception threshold in noise, the APHAB or SSQ. There were, however, significant differences, at primarily 500 to 2,000 Hz in measured FLs between the FF, ASFT, and skull simulator/DSL-BCD targets at 50 and 65 dB SPL.
Conclusions
There were no significant differences in subject performance with two speech measures and subjective responses to two questionnaires for BAHD fittings using ASFT versus using skull simulator/DSL-BCD targets. Differences in FL between the three fitting strategies were present primarily at 500 to 2,000 Hz. Limitations of the study are highlighted along with situations where the skull simulator can play a significantly beneficial role when fitting BAHD devices.DOI : 10.1055/s-0041-1730412|1 Disponible en ligne : Oui En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=288461

Self-reported hearing aid outcomes among older adults are variable and important to improve. The extent of the role of auditory processing in long-term hearing aid outcomes is not well understood.
Purpose
To determine how auditory processing abilities are related to self-reported hearing aid satisfaction and benefit along with either aided audibility alone or exploratory factors suggested by previous literature.
Research Design
Descriptive analyses and multiple regression analyses of cross-sectional self-reported outcomes.
Study Sample
Adult participants, >60 years (n = 78), fitted with bilateral hearing aids to treat symmetric, mild to moderate sensorineural hearing loss.
Data Collection and Analysis
Participants were recruited from a single audiology clinic to complete a series of questionnaires, behavioral assessments, and obtain data from their hearing aids, including real ear measures and data logging of hearing aid use. Multiple linear regressions were used to determine the amount of variance explained by predictive factors in self-reported hearing aid satisfaction and benefit. The primary predictive factors included gap detection threshold, spatial advantage score, dichotic difference score, and aided audibility. Exploratory factors included personality, self-efficacy, self-report of disability, and hearing aid use. All interpretations of statistical significance used p
Results
Gap detection threshold was a statistically significant predictor in both primary regression models with a medium effect size for satisfaction and a small effect size for benefit. When additional exploratory factors were included in the regression models with auditory processing abilities, gap detection and self-efficacy were both significant predictors of hearing aid satisfaction with medium effect sizes, explaining 10 and 17% of the variance, respectively. There were no medium effect sizes found for other predictor variables in either the primary or exploratory hearing aid benefit models. Additional factors were statistically significant in the models, explaining a small amount of variance, but did not meet the medium effect size criterion.
Conclusion
This study provides initial evidence supporting the incorporation of measures of gap detection ability and hearing aid self-efficacy into clinical practice for the interpretation of postfitting long-term hearing aid satisfaction.DOI : 10.1055/s-0041-1728771|1 Disponible en ligne : Oui En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=288509

Therapie sonoreMots-clés : Bruit à large bande(BBN) Résumé : Background
Broadband noise (nonnotched) and notched noise are common sound sources in sound therapy for tinnitus relief. Studies on sound therapy using nonnotched or notched stimuli have reported large and small tinnitus improvements depending on the participant. However, the more effective sound source remains unclear given the among-study methodology differences.
Purpose
This study aimed to evaluate the tinnitus relief effects of sound therapy using stimuli with different spectral characteristics.
Research Design
This was a prospective study involving within-subject (baseline vs. 12-month follow-up) measurements for two groups (notched noise group vs. broadband noise group).
Study Sample
We enrolled 30 adults with subjective and tonal tinnitus (notched noise group: 16, broadband noise group: 14).
Intervention
The participants underwent 3-hour daily sound therapy using either notched noise or broadband noise for 12 months. The stimulus level for sound therapy was set to each participant's mixing point.
Data Collection and Analysis
Tinnitus loudness and the Korean version of the Tinnitus Primary Function Questionnaire score were measured at baseline and at the 12-month follow-up time point.
Results
Both groups showed a significant improvement in tinnitus loudness and the Korean version of the Tinnitus Primary Function Questionnaire score.
Conclusion
Notched and nonnotched stimuli are equally effective at the mixing point in sound therapy for tinnitus relief. Individuals with difficulties in tinnitus frequency measurement could easily undergo sound therapy using nonnotched stimuli.DOI : 10.1055/s-0041-1728701|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=288513

Audiologie ; Compétence culturelle ; Langue des signes américaine (ASL)Mots-clés : Culture sourde Résumé : Background
Historically, the Deaf community and audiologists have had differing views concerning hearing loss intervention. Even so, members of the Deaf community may see an audiologist for a variety of reasons and it is important that audiologists understand how to best work with these individuals. Professional audiological organizations encourage cultural competence when working with different cultures, including the Deaf community.
Purpose
This study investigates audiologists' current cultural competency and exposure to, knowledge of, and attitudes towards Deaf individuals.
Research Design
A survey was sent out to 600 audiologists and descriptive analyses was completed.
Data Collection and Analysis
Study data were managed using REDCap electronic data capture tools and subsequently tabulated for each of the various survey questions.
Results
Findings indicate that audiologists have relatively limited exposure to this population in a clinical setting, most use interpreters, and most would like to take more ASL courses. Audiologists' attitudes were positive in serving members from the Deaf community.
Conclusion
Findings suggest that more education on the use of interpreters would be beneficial. Future research may include examining the Deaf community's experience with audiologists, and the impact of exposure and other variables on the knowledge of and interactions with this population.DOI : 10.1055/s-0041-1729221|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=288517

Collecte de données ; Enfant (6-12 ans) ; Enfant déficient auditif ; Implants cochléaires ; Intervention médicale précoce ; Perception de la paroleRésumé : Background
Considerable variability exists in the speech recognition abilities achieved by children with cochlear implants (CIs) due to varying demographic and performance variables including language abilities.
Purpose
This article examines the factors associated with speech recognition performance of school-aged children with CIs who were grouped by language ability.
Design
This is a single-center cross-sectional study with repeated measures for subjects across two language groups.
Study Sample
Participants included two groups of school-aged children, ages 7 to 17 years, who received unilateral or bilateral CIs by 4 years of age. The High Language group (N = 26) had age-appropriate spoken-language abilities, and the Low Language group (N = 24) had delays in their spoken-language abilities.
Data Collection and Analysis
Group comparisons were conducted to examine the impact of demographic characteristics on word recognition in quiet and sentence recognition in quiet and noise.
Results
Speech recognition in quiet and noise was significantly poorer in the Low Language compared with the High Language group. Greater hours of implant use and better adherence to auditory-verbal (AV) therapy appointments were associated with higher speech recognition in quiet and noise.
Conclusion
To ensure maximal speech recognition in children with low-language outcomes, professionals should develop strategies to ensure that families support full-time CI use and have the means to consistently attend AV appointments.DOI : 10.1055/s-0041-1730413|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=288531

PolariteMots-clés : Ondes de la parole Spectrogramme Amplitude et symétrie temporelle Résumé : Background
The amplitude and temporal asymmetry of the speech waveform are mostly associated with voiced speech utterances and are obvious in recent graphic depictions in the literature. The asymmetries are attributed to the presence and interactions of the major formants characteristic of voicing with possible contributions from the unidirectional air flow that accompanies speaking.
Purpose
This study investigated the amplitude symmetry/asymmetry characteristics (polarity) of speech waveforms that to our knowledge have not been quantified.
Study Sample
Thirty-six spondaic words spoken by two male speakers and two female speakers were selected because they were multisyllabic words providing a reasonable sampling of speech sounds and four recordings were available that were not related to the topic under study.
Research Design
Collectively, the words were segmented into phonemes (vowels [130], diphthongs [77], voiced consonants [258], voiceless consonants [219]), syllables (82), and blends (6). For each segment the following were analyzed separately for the positive and negative datum points: peak amplitude, the percent of the total segment datum points, the root-mean-square (rms) amplitude, and the crest factor.
Data Collection and Analyses
The digitized words (44,100 samples/s; 16-bit) were parsed into 144 files (36 words × 4 speakers), edited, transcribed to numeric values (±1), and stored in a spread sheet in which all analyses were performed with in-house routines. Overall approximately 85% of each waveform was analyzed, which excluded portions of silent intervals, transitions, and diminished waveform endings.
Results
The vowel, diphthong, and syllable segments had durations (180–220 ms) that were about twice as long as the consonant durations (∼90 ms) and peak and rms amplitudes that were 6 to 12 dB higher than the consonant peak and rms amplitudes. Vowel, diphthong, and syllable segments had 10% more positive datum points (55%) than negative points (45%), which suggested temporal asymmetries within the segments. With voiced consonants, the distribution of positive and negative datum points dropped to 52 and 48% and essentially was equal with the voiceless consonants (50.3 and 49.6%). The mean rms amplitudes of the negative datum points were higher than the rms amplitudes for the positive points by 2 dB (vowels, diphthongs, and syllables), 1 dB (voiced consonants), and 0.1 dB (voiceless consonants). The 144 waveforms and segmentations are illustrated in the Supplementary Material along with the tabularized positive and negative segment characteristics.
Conclusions
The temporal and amplitude waveform asymmetries were by far most notable in segments that had a voicing component, which included the voiced consonants. These asymmetries were characterized by larger envelopes and more energy in the negative side of the waveform segment than in the positive side. Interestingly, these segments had more positive datum points than negative points, which indicated temporal asymmetry. All aspects of the voiceless consonants were equally divided between the positive and negative domains. There were female/male differences but with these limited samples such differences should not be generalized beyond the speakers in this study. The influence of the temporal and amplitude asymmetries on monaural word-recognition performance is thought to be egligible.DOI : 10.1055/s-0041-1730959|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=288535

Titre : Evaluation of Postinfection Hearing with Audiological Tests in Patients with COVID-19 : A Case–Control Study Type de document : Article Auteurs : Mehtap Koparal ; Cuneyt Yılmazer Année de publication : 2021 Article en page(s) : p. 464-468 Note générale : DOI: 10.1055/s-0041-1730960 Langues : Anglais (eng) Descripteurs : HE Vinci
Audiométrie ; Cochlée ; COVID-19 ; Perte d'auditionRésumé : Background
Some viral infections can cause congenital or acquired unilateral or bilateral hearing loss. It is predicted that the coronavirus disease 2019 (COVID-19) virus, which can affect many systems in the body, may also have a negative effect on hearing.
Purpose
This study evaluated the effects of COVID-19 infection on pure-tone average.
Research Design
A case–control study.
Materials and Methods
A total of 104 volunteers (48 control, 56 experimental group) who applied to the ENT clinic of Adıyaman University Training and Research Hospital were included in this study. After the detailed clinical examination and medical history, 13 volunteers of the experimental group and 5 volunteers from the control group were excluded from the study. In this way, each group consisted of 43 volunteers. While the experimental group consisted of patients who did not have any hearing problems before but had COVID-19. The control group consisted of healthy volunteers who did not have any hearing problems and were not infected with COVİD-19. Audiological test was applied to all volunteers to determine their pure-tone average. On the data obtained, it was analyzed whether COVID-19 affects the pure-tone average and how it changes according to variables such as age and gender.
Results
The evaluation of the 43 (50.0%) COVID-19-positive patients and 43 (50.0%) healthy controls showed no significant differences (p > 0.05) at 250 and 500 Hz, whereas at 4000, 6000, and 8000 Hz, the two groups differed significantly. In addition, significant differences were found in the left and right ears at 1000 and 2000 Hz (p 0.05)
Conclusion
The pure-tone average of COVID-19 positive patients was significantly worse than those of the healthy control group. Thus, COVID-19 should also be considered in patients presenting with unexplained hearing loss. Further studies should investigate the effects of COVID-19 on hearing and the underlying pathophysiology.DOI : 10.1055/s-0041-1730960|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=288539

Implants cochléaires ; Perception de la parole ; Reconnaissance de la paroleRésumé : Background
Speech recognition in noisy environments is a challenge for both cochlear implant (CI) users and device manufacturers. CI manufacturers have been investing in technological innovations for processors and researching strategies to improve signal processing and signal design for better aesthetic acceptance and everyday use.
Purpose
This study aimed to compare speech recognition in CI users using off-the-ear (OTE) and behind-the-ear (BTE) processors.
Design
A cross-sectional study was conducted with 51 CI recipients, all users of the BTE Nucleus 5 (CP810) sound processor. Speech perception performances were compared in quiet and noisy conditions using the BTE sound processor Nucleus 5 (N5) and OTE sound processor Kanso. Each participant was tested with the Brazilian-Portuguese version of the hearing in noise test using each sound processor in a randomized order. Three test conditions were analyzed with both sound processors: (i) speech level fixed at 65 decibel sound pressure level in a quiet, (ii) speech and noise at fixed levels, and (iii) adaptive speech levels with a fixed noise level. To determine the relative performance of OTE with respect to BTE, paired comparison analyses were performed.
Results
The paired t-tests showed no significant difference between the N5 and Kanso in quiet conditions. In all noise conditions, the performance of the OTE (Kanso) sound processor was superior to that of the BTE (N5), regardless of the order in which they were used. With the speech and noise at fixed levels, a significant mean 8.1 percentage point difference was seen between Kanso (78.10%) and N5 (70.7%) in the sentence scores.
Conclusion
CI users had a lower signal-to-noise ratio and a higher percentage of sentence recognition with the OTE processor than with the BTE processor.DOI : 10.1055/s-0041-1735252|1 Disponible en ligne : Oui En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=288545

Titre : Motivational Interviewing for Hearing Aid Use : A Systematic Meta-Analysis on Its Potential for Adult Patients with Hearing Loss Type de document : Article Auteurs : Alice Liu ; Bella Wu ; Desmond A. Nunez Année de publication : 2021 Article en page(s) : p. 332-338 Note générale : DOI: 10.1055/s-0041-1728755 Langues : Anglais (eng) Descripteurs : HE Vinci
Aides auditives ; Amplification auditive ; Entretien motivationnelRésumé : Purpose
The aim of the study is to conduct a meta-analysis examining the impact of motivational interviewing (MI) on hearing aid (HA) use compared with standard care.
Research Design
The research design is a systematic review and meta-analysis. Cochrane ENT, Central, Medline, Web of Science, ICTRP, and ClinicalTrials.gov electronic databases were searched. Inclusion criteria consisted of randomized controlled trials (RCTs) published between 1988 and 2018 that compared MI to standard care.
Study Sample
study sample consists of four RCTs, investigating a total of 176 patients.
Data Collection and Analysis
RevMan 5.3 and a random effect model were used for analysis.
Results
The standardized mean difference in data-logged hours of HA use was not statistically significant (0.34 [95% confidence interval or CI: −0.10, 0.78; p = 0.13]). The mean difference for user-reported outcomes on the International Outcome Inventory—Hearing Aids of 0.41 [CI: −1.00, 1.82; p = 0.57] was also not significant.
Conclusion
There is no current evidence that MI significantly improves HA use or user-reported outcomes. However, there were limited studies included in this review and further research is indicated.DOI : 10.1055/s-0041-1728755|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Format de la ressource électronique : Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=286503

Titre : Comparing Simultaneous Electrocochleography and Auditory Brainstem Response Measurements Using Three Different Extratympanic Electrodes Type de document : Article Auteurs : Shannon M. Lefler ; Wafaa A. Kaf ; John A. Ferraro Année de publication : 2021 Article en page(s) : p. 339-346 Note générale : DOI: 10.1055/s-0041-1727273 Langues : Anglais (eng) Descripteurs : HE Vinci
Electrocochléographie ; Potentiels d'action ; Potentiels évoqués auditifs du tronc cérébral (ABR)Mots-clés : Summating potential (SP) Résumé : Background
Various extratympanic recording electrodes have been used to make electrocochleography (ECochG) and auditory brainstem response (ABR) measurements in clinics, translational research, and basic science laboratories. However, differences may exist in ECochG and ABR measurements depending on the different types of extratympanic electrodes that are used.
Purpose
The purpose of this research is to compare simultaneously recorded ECochG and ABR responses using three different extratympanic electrodes. This research helps clinicians and researchers to understand how electrode types and recording sites influence EcochG and ABR results. In addition, our findings could provide more normative data to the ECochG and ABR literature as well as give perspective on a preferred electrode approach when performing simultaneous ECochG and ABR testing.
Research Design
Ours was a repeated-measures study with measurements being made from individual participants on two separate sessions.
Study Sample
Twenty young adult females with normal hearing.
Procedure
A three-channel recording system was used to simultaneously record ECochG and ABR measurements in response to alternating polarity click stimuli. In each session, measurements were simultaneously recorded with a TipTrode electrode and one of the tympanic membrane (TM) electrodes.
Data Collection and Analysis Suprathreshold summating potential (SP) and action potential (AP) of the ECochG and waves I, III, and V of the ABR, and threshold responses (AP and wave V) were identified.
Results
Compared with the ear canal TipTrode electrode, TM electrodes yielded suprathreshold amplitudes that were larger than those from the ear canal electrode, smaller SP–AP ratios, lower AP thresholds, and less variability. These findings can help guide choices made by clinicians, translational investigators, and basic science researchers on which type of extra-tympanic electrode to use for their intended purpose.DOI : 10.1055/s-0041-1727273|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=286623

Ecoute dichotiqueMots-clés : Right ear advantage (REA) Voice onset time (VOT) Résumé : Background
The right ear advantage (REA) observed for dichotic CV (DCV) testing in Indian languages is seen to be smaller compared with the observations in several studies in English and other languages.
Purpose
The present study aims to explore whether the differences in the temporal alignment of consonant–vowel (CV) stimuli used for the dichotic task is a contributing factor that can explain the smaller REAs observed in Indian languages.
Research Design
The study compared the laterality index (LI) values between DCV test results obtained using CV stimuli that were temporally aligned at the acoustic onset versus the burst onset, with 0 milliseconds lag between the right and left ears.
Study Sample
A total of 50 right-handed individuals (native speakers of Kannada language) in the age range of 17 to 30 years with normal hearing sensitivity participated in the study.
Data Collection and Analysis
The participants' responses to the two sets of DCV stimuli were recorded and compared. LI was calculated for the overall scores as well as for specific voiced and unvoiced segment combinations. To test the reliability of the findings, 10 of the participants were re-tested using the same stimuli and the data were checked for reliability.
Results
The overall LI was 15.1% for the stimuli temporally aligned at the burst onset, whereas it was 5.7% for the stimuli temporally aligned at the acoustic onset. The difference in LI was not significant between the alignment conditions for unvoiced–unvoiced and voiced–voiced CV combinations, but this difference was significant for the unvoiced–voiced and voiced–unvoiced CV combinations. Comparing test and re-test scores showed good reliability.
Conclusion
The results support our hypothesis that smaller REA observed in DCV task in Indian languages was due to the temporal alignment of CV stimuli. In the acoustic-onset-aligned condition, presenting pairs contrasting in the voicing feature tends to cancel out a relative ear advantage.DOI : 10.1055/s-0041-1728799|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=286645

Rehabilitation audiologique

Aides auditives ; Différences individuellesRésumé : Background
Age-related changes (both normal and pathological), and health literacy are relevant to audiological practice. Changes associated with the musculoskeletal, vascular, and nervous systems drive manual, visual, and cognitive function. These in turn affect the capabilities required for effective hearing aid (HA) skill acquisition, use, and management. Meanwhile, health literacy influences the ability to gain access to, understand, and use information, which is important for promoting and maintaining HA use and management. Understanding the interindividual variability of these variables can help audiologists characterize those individuals who might have suboptimal HA outcomes. This knowledge can then inform better clinical practices and guide implementation of processes to improve care quality and outcomes.
Purpose
The aim of the study is to assess the variation in manual, visual, and cognitive function, and health literacy, among community-dwelling older individuals, and to determine whether and which of these variables are associated with reported HA outcome and/or the knowledge and skill to manage HAs.
Research Design
Data presented here were collected as part of an efficacy trial of four variants of HA orientation. The data were collected at baseline (prior to HA fitting) and after 4 to 8 weeks of HA use.
Study Sample
The study sample consists of 265 U.S. Veterans aged 51 to 87 years with no previous HA experience who were scheduled to receive their first pair of HAs from the Veterans Administration.
Data Collection and Analysis
We assessed baseline measures of hand function, vision, cognition, and health literacy just prior to participants receiving their first pair of HAs. HA management skills and knowledge, and HA outcome were measured after 4 to 8 weeks of HA use using the Hearing Aid Skills and Knowledge (HASK) and International Outcomes Inventory for Hearing Aids (IOI-HA), respectively. Data collected here was compared with published norms to assess variation in baseline measures. Associations between baseline performance and outcomes data were examined using t-tests comparing participants who performed at or above age-based norms with those who performed below age-based norms.
Results
Participants' performance on the baseline measures was highly variable, with the proportions of individuals performing below norms varying by test measure. When combining data across the nine baseline measures, approximately 10% of participants performed below published norms on five or more measures, and 85% performed below norms on at least one measure. Poor manual dexterity, ability to learn a new task, and ability to draw inferences from spoken information negatively impacted HA management and outcome.
Conclusion
There was a considerable heterogeneity among a community-dwelling sample of first time HA users in terms of sensory, cognitive, and motor function. Clinicians should consider modifying their clinical practice to account for such heterogeneity and best support their patients in adapting to new HAs.DOI : 10.1055/s-0041-1728800|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=286647

Cellules ciliées auditives externes ; Electrocochléographie ; Potentiels microphoniques cochléairesRésumé : Background
Understanding the functional differences between crossed and uncrossed medial olivocochlear (MOC) neurons has been of interest to researchers for decades. Previous reports revealed conflicting results about which MOC pathway, crossed or uncrossed, is stronger in humans. Both crossed and uncrossed MOC neurons synapse at the base of the outer hair cells (OHCs) in each ear. OHCs generate the cochlear microphonic, which is a major contributor to the cochlear response (CR)
Purpose
The current study investigated the effects of eliciting the crossed and uncrossed MOC reflex (MOCR) on CR in humans with three levels of noise.
Research Design
Normal-hearing, young adults (n = 16) participated in this study. The CR was recorded using 500 Hz tone-burst stimuli presented at 80 dB nHL. To examine the crossed and uncrossed MOCR, CR was recorded without and with continuous ipsilateral or contralateral broadband noise (BBN) at three levels (40, 50, and 60 dB SPL).
Data Analysis
Analysis of the CR was completed using the amplitude of the response extracted using fast Fourier transform. Statistical analysis was completed using repeated measures analysis of variance and post-hoc analysis.
Results
Compared with baseline, the presentation of BBN, specifically contralaterally, resulted in CR enhancement with no significant difference as a function of the three BBN levels. Greater enhancement of the CR amplitude was observed with contralateral than ipsilateral BBN elicitor.
Conclusions
The current findings suggest that a contralateral elicitor of the uncrossed MOC pathway results in a larger CR amplitude enhancement compared with an ipsilateral elicitor of the crossed MOC pathway, regardless of the elicitor level. Eliciting the MOCR appears to modulate the OHCs function. Furthermore, assessing the MOCR with the 500 Hz CR with BBN elicitors at moderate levels should separate its effects (i.e., increase response amplitude) from those associated with the middle ear muscle reflex (i.e., reduce response amplitude).DOI : 10.1055/s-0041-1728649|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=286832

Aptitude auditiveRésumé : Background
A frequent concern surrounding amplification with hearing aids for patients with sensorineural hearing loss is whether these devices negatively affect hearing ability. To date, there have been few studies examining the long-term effects of amplification on audiometric outcomes in adults.
Purpose
In the present study, we examined how hearing aids affect standard audiometric outcomes over long-term periods of follow-up.
Research Design
We retrospectively collected audiometric data in adults with sensorineural hearing loss, constructing a model of long-term outcomes.
Study Sample
This retrospective cohort study included 802 ears from 401 adult patients with bilateral sensorineural hearing loss eligible for amplification with hearing aids at a single institution.
Intervention
Of the eligible patients, 88 were aided bilaterally, and 313 were unaided.
Data Collection and Analysis
We examined the standard three-frequency pure-tone average (PTA3-Freq), a novel extended pure-tone average (PTAExt), and word recognition score (WRS) per-ear at each encounter. We then modeled the association between the use of hearing aids for 5 years and these audiometric outcomes using targeted maximum likelihood estimation.
Results
In comparing aided and unaided ears at the end of 5 years, there were discernible effects for all measurements. The PTA3-Freq was 5 dB greater in aided ears (95% CI: 1.37–8.64, p = 0.007), WRS was 4.5 percentage points lower in aided ears (95% CI: −9.14 to 0.15, p = 0.058), and PTAExt was 5 dB greater in aided ears (95% CI: 2.18–7.82, p
Conclusion
Our analysis revealed discernible effects of 5 years of hearing aid use on hearing ability, specifically as measured by the PTA3-Freq, novel PTAExt, and WRS, suggesting a greater decline in hearing ability in patients using hearing aids. Future studies are needed to examine these effects between treatment groups over longer periods of time and in more heterogeneous populations to improve clinical practice guidelines and safety of both prescriptive fitting nonprescriptive amplification.DOI : 10.1055/s-0041-1731592|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=286833

Potentiels évoqués auditifs du tronc cérébral (ABR) ; Trouble du spectre autistique (TSA) ; Troubles de la perception auditiveRésumé : Background
Neurological, structural, and behavioral abnormalities are widely reported in individuals with autism spectrum disorder (ASD); yet there are no objective markers to date. We postulated that by using dominant and nondominant ear data, underlying differences in auditory evoked potentials (AEPs) between ASD and control groups can be recognized.
Purpose
The primary purpose was to identify if significant differences exist in AEPs recorded from dominant and nondominant ear stimulation in (1) children with ASD and their matched controls, (2) adults with ASD and their matched controls, and (3) a combined child and adult ASD group and control group. The secondary purpose was to explore the association between the significant findings of this study with those obtained in our previous study that evaluated the effects of auditory training on AEPs in individuals with ASD.
Research Design
Factorial analysis of variance with interaction was performed.
Study Sample
Forty subjects with normal hearing between the ages of 9 and 25 years were included. Eleven children and 9 adults with ASD were age- and gender-matched with neurotypical peers.
Data Collection and Analysis
Auditory brainstem responses (ABRs) and auditory late responses (ALRs) were recorded. Adult and child ASD subjects were compared with non-ASD adult and child control subjects, respectively. The combined child and adult ASD group was compared with the combined child and adult control group.
Results
No significant differences in ABR latency or amplitude were observed between ASD and control groups. ALR N1 amplitude in the dominant ear was significantly smaller for the ASD adult group compared with their control group. Combined child and adult data showed significantly smaller amplitude for ALR N1 and longer ALR P2 latency in the dominant ear for the ASD group compared with the control group. In our earlier study, the top predictor of behavioral improvement following auditory training was ALR N1 amplitude in the dominant ear. Correspondingly, the ALR N1 amplitude in the dominant ear yielded group differences in the current study.
Conclusions
ALR peak N1 amplitude is proposed as the most feasible AEP marker in the evaluation of ASD.DOI : 10.1055/s-0041-1730365|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=286834

Cartilage conduction hearing aids (CCHAs) were newly devised and spread fast in Japan since their launch in 2017. However, little knowledge is available for this new device.
Purpose
The aim of this study was to establish the knowledge of CCHAs and suggest their indication.
Research Design
Correlational study.
Study Sample
A total 256 patients were registered.
Data Collection and Analysis
The fitting of CCHAs was surveyed in nine institutions. The outcomes were assessed by audiometric tests. The patients were classified into seven groups, depending on the ear conditions. The clinical characteristics, assessment results, and purchase rates were compared among the groups. The assessment results of CCHAs were also compared with those of previously used hearing aids.
Results
Most patients who used CCHAs were classified into the bilateral closed (aural atresia or severe stenosis) ear (n = 65) or unilateral closed ear (n = 124) groups. The patients in these groups achieved good benefits that resulted in a high purchase rate. The bilateral continuous otorrhea group also supported a high purchase rate, although the benefits of CCHAs were not always excellent. In contrast, the purchase rate was poor in the patients who could use air conduction hearing aids (ACHAs) without absolute problems. As for using a CCHA as a contralateral routing of signals hearing aid, the benefits depended on the patients.
Conclusions
CCHAs are considered as a great option not only to the patients with closed ears but also to those who had difficulties in ACHAs usage.DOI : 10.1055/s-0041-1728758|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=286835

Titre : Relationship between Verbal and Nonverbal Tests of Auditory Temporal Processing Type de document : Article Auteurs : Marni Novick ; Jay R.

Gap-in-noise (GIN) ; Reconnaissance des phrasesRésumé : Background
Audiologists may choose to evaluate auditory temporal processing in assessing auditory processing abilities. Some may decide to use measures of nonverbal stimuli such as tonal or noise gap detection. Others may decide to use verbal measures such as time compressed sentences (TCS). Many may choose to use both.
Purpose
Since people typically come to audiologists for auditory processing testing complaining of problems processing verbal stimuli, the question arises whether measures of nonverbal stimuli provide evidence regarding a person's abilities to processing verbal stimuli. That is, are there significant correlations between measures of verbal stimuli and nonverbal stimuli that are used to evaluate auditory temporal processing?
Research Design
The present investigation is an exploratory study using file review of 104 people seen for routine auditory processing evaluations by the authors.
Study Sample
A file review was completed based on data from 104 people seen for auditory processing evaluations.
Data Collection and Analyses
The data from these 104 files were used to evaluate whether there are any correlations between verbal and nonverbal measures of auditory temporal processing. The verbal measure used was the TCS subtest of the SCAN-3 while the nonverbal measures included the gap detection screening from the SCAN-3 as well as the gaps-in-noise measures. Results from these tests were compared to determine whether any significant correlations were found based on results from Pearson product moment correlational analyses.
Results
None of the nonverbal measures were found to have a significant correlation with the TCS test findings based on the Pearson correlations used to analyze the data.
Conclusion
Results indicate that there are no significant correlations (relationships) between measures of auditory temporal processing using nonverbal stimuli versus verbal stimuli based on the tests used in the present investigation. These findings lead to a conclusion that tests using nonverbal stimuli are measuring different auditory processes than the measure of verbal stimuli used in the present investigation. Since people typically come complaining about understanding verbal input, it is concluded that audiologists should use some verbal measure of auditory temporal processing in their auditory processing test battery.DOI : 10.1055/s-0041-1723042|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=273574

Crâne ; Epreuves vestibulaires caloriques (VNG) ; Nystagmus physiologique ; Potentiels évoqués vestibulaires myogéniques (cVEMP) (mVEMP) (oVEMP) ; VibrationMots-clés : Skull vibration-induced nystagmus testing (SVINT) Résumé : Background
How significant asymmetries in otolith organ function in the presence of symmetrical and asymmetrical semicircular canal function influence skull vibration-induced nystagmus testing (SVINT) has not been well described.
Purpose
The aim of the study is to examine the agreement between SVINT and caloric testing, ocular vestibular-evoked myogenic potentials (oVEMP), and cervical vestibular-evoked myogenic potentials (cVEMP) for detecting asymmetric vestibular function.
Research Design
This is a retrospective study of patients presenting with the chief complaint of vertigo, dizziness, or imbalance.
Study Sample
A total of 812 patients were studied with a median age at testing of 59 years (interquartile range 46–70; range 18–93) and included 475 (59%) women.
Intervention
Either the monothermal warm caloric test or alternate binaural bithermal caloric test, oVEMP, and cVEMP tests were administered to all patients. All patients underwent the SVINT prior to vestibular laboratory testing.
Data Collection and Analysis
Agreement between tests categorized as normal versus abnormal was summarized using percent concordance (PC). Sensitivity and specificity values were calculated for SVINT compared with other tests of vestibular function.
Results
There was higher agreement between ipsilateral and contralateral SVINT with the caloric test (PC = 80% and 81%, respectively) compared with oVEMP (PC = 63% and 64%, respectively) and cVEMP (PC = 76% and 78%, respectively). Ipsilateral and contralateral SVINT showed higher sensitivity for the caloric test (sensitivity = 47% and 36%, respectively) compared with oVEMP (sensitivity = 26% and 21%, respectively), or cVEMP (sensitivity = 33% vs. 27%, respectively). Specificity of SVINT was high (>80%) for all assessments of vestibular function.
Conclusion
The presence of SVIN is a useful indicator of the asymmetry of vestibular function between the two ears when making judgments about semicircular canal asymmetry but is less sensitive to asymmetries in otolith organ function.DOI : 10.1055/s-0041-1723039|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=273575

Complications postopératoires ; Comportement de réduction des risques ; Prothèse auditive implantableMots-clés : Implant lifts Résumé : Background
Implant lifts were recently introduced to facilitate implantation of the Bonebridge and to reduce the risk of uncovering the sigmoid sinus and/or dura.
Purpose
The current study analyzed medical, technical, and audiological outcomes of implantation with the Bonebridge implant using lifts.
Research Design
This was a retrospective study on all consecutive patients implanted with a bone-conduction hearing implant at a tertiary medical referral center between March 2012 and October 2018. Outcome measures were complications, explantations, and revisions and the mean time of implant use. Audiological results were assessed as well. Outcomes were evaluated for devices implanted with BCI Lifts and compared with those implanted without lifts.
Results
In the study period, 13 out of a total of 54 implantations were conducted using one or two 1- to 4-mm BCI Lifts. During the follow-up period, two complications occurred and both in patients implanted without lifts (2/41; 4.9%). All patients in the lifts group were using the implant at the end of observation period. No statistically significant difference was observed in functional hearing gain or word-recognition improvement at 65 dB between two groups.
Conclusions
The use of BCI Lifts in Bonebridge implantations was not associated with adverse events during the observation period. The clinical follow-up revealed no complications in implantations requiring lifts. Furthermore, the functional hearing gain and the word-recognition improvement did not differ from those of devices implanted without lifts.

Ecoute dichotiqueMots-clés : Phénomène de décalage dichotique Résumé : Background
Dichotic listening deficit (DLD) is a common sign in children showing learning problem and is identified during auditory processing assessment. A dichotic listening training program was developed in which the weak ear lags behind the strong ear in time and has certain practices for switching attention between the ears and auditory memory.
Purpose
The aim of the present study was to evaluate the effectiveness of this treatment program on dichotic performance of primary school children showing DLD.
Research Design
A pre/post clinical trial without control study.
Study Sample
Twenty-five primary school children, aged 7 to 12 years (mean = 9.3 years), showing DLD.
Data Collection and Analysis
Several primary schools referred the children with learning difficulty to us. We defined learning difficulty as a score of 2 and lower on a five-point scale in at least two primary school courses in the current semester. The children with DLD participated in listening practices three times a week for 10 weeks, each session lasting for 30 minutes. The practices started with one pair of dichotic digits and ended in practice with sentences. The weak ear lag varied from 100 to 1,000 milliseconds. In the last stage of the practices, the precued and postcued directed response aimed at strengthening auditory memory and switching attention between the ears. The results obtained by the tests of dichotic digits, competing words, and competing sentences before and after the intervention were compared using paired t-test. Hedges's g was calculated as the effect size.
Results
Comparison of the results of pretraining and those of posttraining revealed that the average dominant ear (DE) and nondominant ear (NDE) scores in dichotic listening tests improved significantly with medium-to-large effect sizes. It was also found that the mean change in the NDE score of the children was significantly greater than that of the DE score for all the tests.
Conclusion
Dichotic interaural time difference training that employed dichotic lag phenomenon followed by directed response practices significantly improved the DE and the NDE scores of the schoolchildren with DLD.DOI : 10.1055/s-0041-1728753|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=273577

Titre : Investigating the Effect of Hearing Aid Use on the Balance Status of Children with Severe to Profound Congenital Hearing Loss Using the Pediatric Clinical Test of Sensory Interaction for Balance Type de document : Article Auteurs : Farzad Hamzehpour ; Aghil Absalan ; Ebrahim Pirasteh ; Zahra Sharafi ; Hamideh Arbabsarjoo Année de publication : 2021 Article en page(s) : p. 303-307 Note générale : 10.1055/s-0041-1728754 Langues : Anglais (eng) Descripteurs : HE Vinci
Aides auditives ; Enfant (6-12 ans) ; Equilibration ; Équilibre postural ; Interaction sensorielle ; Perte d'auditionRésumé : Background
Since the hearing and vestibular organs are close to each other, the correlation between hearing and balance is one of the principal issues, especially in people with hearing loss.
Purpose
In this study, the effect of the auditory system on human balance performance was investigated by comparing the balance status of hearing-impaired children in the aided and unaided situations.
Research Design
In this cross-sectional study a group of children were assigned the task to compare the balance sways in two aided and unaided situations.
Study Sampling
A total of 90 children aged 7 to 10 years with severe to profound congenital hearing loss and the healthy vestibular system of both genders served as the research population.
Data Collection and Analysis
After a complete evaluation of the hearing and vestibular system and validation of the hearing aid performance, body sway was recorded using the pediatric clinical test of sensory interaction for balance in aided and unaided situations in the presence of background noise from the speaker.
Results
According to this study, there was no difference in body sway in aided and unaided situations for conditions 1, 2, and 3. In comparison, in conditions 4, 5, and 6 of the test, there was a statistically significant difference in body sway between aided and unaided situations. However, there was no difference in the sway of the body in aided and unaided situations between girls and boys.
Conclusion
According to this study, hearing aids can improve balance in challenging listening environments.DOI : 10.1055/s-0041-1728754|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=273592

Potentiel evoque otolithique
HE Vinci
Nerf trijumeau ; Potentiels évoqués vestibulaires myogéniques (cVEMP) (mVEMP) (oVEMP) ; Réflexe vestibulo-oculaire (VOR)Résumé : Background
Masseter vestibular evoked myogenic potential (mVEMP) is a recent tool for the assessment of vestibular and trigeminal pathways. Though a few studies have recorded mVEMP using click stimuli, there are no reports of these potentials using the more conventional VEMP eliciting stimuli, the tone bursts.
Purpose
The aim of the study is to establish normative values and determine the test–retest reliability of tone burst evoked mVEMP.
Research Design
The research design type is normative study design.
Study Sample
Forty-four healthy participants without hearing and vestibular deficits in the age range of 18 to 50 years participated in the study.
Data Collection and Analysis
All participants underwent mVEMP testing using 500 Hz tone-burst stimuli at 125 dB peSPL. Ten participants underwent second mVEMP testing within 1 month of the initial testing to estimate the test–retest reliability.
Results
Tone burst mVEMP showed robust responses in all participants. There were no significant ear and sex differences on any mVEMP parameter (p > 0.05); however, males had significantly higher EMG normalized peak-to-peak amplitude than females. Intraclass correlation coefficient (ICC) values of tone burst mVEMP showed excellent test–retest reliability (ICC >0.75) for ipsilateral and contralateral p11 latency, ipsilateral EMG normalized p11-n21 peak to peak amplitude, and amplitude asymmetry ratio. Fair and good test–retest reliability (0.4 0.75) was observed for ipsilateral and contralateral n21 latency, contralateral EMG normalized peak-to-peak amplitude, and amplitude asymmetry ratio.
Conclusion
Tone burst mVEMP is a robust and reliable test for evaluating the functional integrity of the vestibulomasseteric reflex pathway.DOI : 10.1055/s-0041-1728718|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=273596

Compréhension dans le bruit ; Digit in noise (DIN) ; Enfant (6-12 ans) ; Intelligibilité de la parole ; PERCEPTION BINAURALE ; Seuil de réception de la parole (SRT)Résumé : Background
Digits-in-noise (DIN) tests have become popular for hearing screening over the past 15 years. Several recent studies have highlighted the potential utility of DIN as a school-aged hearing test. However, age may influence test performance in children due to maturation. In addition, a new antiphasic stimulus paradigm has been introduced, allowing binaural intelligibility level difference (BILD) to be measured by using a combination of conventional diotic and antiphasic DIN.
Purpose
This study determined age-specific normative data for diotic and antiphasic DIN, and a derived measure, BILD, in children. A secondary aim evaluated the validity of DIN as a smartphone self-test in a subgroup of young children.
Research Design
A cross-sectional, quantitative design was used. Participants with confirmed normal audiometric hearing were tested with a diotic and antiphasic DIN. During the test, arrangements of three spoken digits were presented in noise via headphones at varying signal-to-noise ratio (SNR). Researchers entered each three-digit spoken sequence repeated by the participant on a smartphone keypad.
Study Sample
Overall, 621 (428 male and 193 female) normal hearing children (bilateral pure tone threshold of ≤ 20 dB hearing level at 1, 2, and 4 kHz) ranging between the ages of 6 and 13 years were recruited. A subgroup of 7-year-olds (n = 30), complying with the same selection criteria, was selected to determine the validity of self-testing.
Data Collection and Analysis
DIN testing was completed via headphones coupled to a smartphone. Diotic and antiphasic DIN speech recognition thresholds (SRTs) were analyzed and compared for each age group. BILD was calculated through subtraction of antiphasic from diotic SRTs. Multiple linear regressions were run to determine the effect of age on SRT and BILD. In addition, piecewise linear regressions were fit across different age groups. Wilcoxon signed-rank tests were used to determine differences between self- and facilitated tests.
Results
Age was a significant predictor, of both diotic and antiphasic DIN SRTs (p 0.05).
Conclusions
Increasing age was significantly associated with improved SRT and BILD using diotic and antiphasic DINs. DIN could be used as a smartphone self-test in young children from 7 years of age with appropriate quality control measures to avoid potential false positives.DOI : 10.1055/s-0041-1727274|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=273607

Déficience vestibulaire ; Dépersonnalisation ; Fonction vestibulaire ; Membrane des statoconies ; Présentations de cas ; VertigeRésumé : Background
We describe herein the case of a patient whose primary complaints were episodic vertigo and “depersonalization,” a sensation of detachment from his own body.
Purpose
This case study aims to further clinical knowledge and insight into the clinical evaluation of vertiginous patients with complaints of depersonalization.
Research Design
This is a case study.
Data Collection and Analysis
A retrospective chart review of vestibular function testing done on a vertiginous patient with complaints of depersonalization was performed.
Results
Vestibular function testing revealed absent cervical and ocular vestibular evoked myogenic potentials on the left side with normal vHIT or video Head Impulse Test, videonystagmography, and rotational chair results, suggesting peripheral vestibular impairment isolated to the left saccule and utricle.
Conclusion
The otolith end organ impairment explains the patient's postural deviation to the left side during attempts to ambulate. We recommend that clinicians should be attentive to patient complaints of depersonalization and perform vestibular evoked myogenic potential testing to determine whether evidence of at least a unilateral peripheral otolith end organ impairment exists.DOI : 10.1055/s-0041-1723040|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=273608

Therapie sonoreRésumé : Background
Sound therapy is generally considered as an effective method for relieving tinnitus. There have been various reports on the effects of tinnitus interventions involving sound therapy as a component; however, there have been only a small number of reports on the effects of sound therapy itself on tinnitus.
Purpose
The aim of the study is to elucidate whether sound therapy significantly improves tinnitus as determined by subjective measurements.
Research Design
Prospective study involves within-subject (baseline, 3-month, 6-month) measurements.
Study Sample
This includes 16 adults with subjective and sensorineural tinnitus.
Intervention
Participants undertook sound therapy for 3 hours a day for 6 months. The level of stimulus for sound therapy was set to the mixing point of each participant. No counseling was provided.
Data Collection and Analysis
Participants rated the visual analog scale for loudness and annoyance using a numeric 0 to 100 point scale and completed the Korean version of the Tinnitus Primary Function Questionnaire at the baseline, 3-month, and 6-month time points.
Results
Sound therapy led to significant improvements of tinnitus in participants in all subjective measurements. Significant effects were found not only between the baseline and 3-month but also between the 3-month and 6-month follow-ups.
Conclusion
Results of the present study showed that the sound therapy alone led to significant improvements of tinnitus in participants as assessed by subjective measurements. To improve the effects of sound therapy, consistent sound therapy may be required for a certain period of time such as 3 hours a day over a 6-month period.DOI : 10.1055/s-0041-1722984|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=273010

Cabine audiometriqueRésumé : Objective
For patients who have received cochlear implants (CIs), speech-perception testing requires specialized equipment. This limits locations where these services can be provided, which can introduce barriers for provision of care. Providing speech test stimuli directly to the CI via wireless digital audio streaming (DAS) or wired direct audio input (DAI) allows for testing without the need for a sound booth (SB). A few studies have investigated the use of DAI for testing speech perception in CIs, but none have evaluated DAS. The goal of this study was to compare speech perception testing in CI users via DAS versus a traditional SB to determine if differences exist between the two presentation modes. We also sought to determine whether pre-processing the DAS signal with room acoustics (reverberation and noise floor) to emulate the SB environment would affect performance differences between the SB and DAS.
Design
In Experiment 1, speech perception was measured for monosyllabic words in quiet and sentences in quiet and in noise. Scores were obtained in a SB and compared to those obtained via DAS with unprocessed speech (DAS-U) for 11 adult CI users (12 ears). In Experiment 2, speech perception was measured for sentences in noise, where both the speech and noise stimuli were pre-processed to emulate the SB environment. Scores were obtained for 11 adult CI users (12 ears) in the SB, via DAS-U, and via DAS with the processed speech (DAS-P).
Results
For Experiment 1, there was no significant difference between SB and DAS-U conditions for words or sentences in quiet. However, DAS-U scores were significantly better than SB scores for sentences in noise. For Experiment 2, there was no significant difference between the SB and DAS-P conditions. Similar to Experiment 1, DAS-U scores were significantly better than SB or DAS-P scores.
Conclusions
By pre-processing the test materials to emulate the noise and reverberation characteristics of a traditional SB, we can account for differences in speech-perception scores between those obtained via DAS and in a SB.DOI : 10.1055/s-0041-1722990|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=273014

Titre : An Examination of Asymmetry in Adult Tympanometric Measures Type de document : Article Auteurs : Andrew Stuart ; Emma K. Tomaszewski ; Baylee M. Engelhardt Année de publication : 2021 Article en page(s) : p. 229-234 Note générale : DOI: 10.1055/s-0041-1722946 Langues : Anglais (eng) Descripteurs : HE Vinci
Admittance acoustique ; Conduit auditif externe (CAE) ; Pression ; Tympanométrie ; VolumeRésumé : Background
During audiologic evaluations, an examination of interaural asymmetry is commonly evaluated. To date, however, interaural differences for tympanometric indices have not been reported for adults. Without documented tympanometric right-left differences, one cannot determine if asymmetries are normal or are indicative of significant clinical asymmetries.
Purpose
The purpose of this study was to investigate interaural asymmetries in peak compensated static acoustic admittance (Ytm), equivalent ear canal volume (Vea), tympanometric peak pressure (TPP), and tympanometric width (TW) in normal adults.
Research Design
Descriptive, correlational, and inferential measures designs were employed.
Study Sample
Participants were 188 otologically normal Caucasian young adults (i.e., 77 females and 111 males; M = 23.0 years, standard deviation [SD] = 2.7, range = 18–30 years).
Data Collection and Analyses
Ytm, Vea, TPP, and TW measures were obtained bilaterally from an admittance tympanogram using a 226 Hz probe tone. Separate two-factor mixed measures analysis of variance examined the effect of ear and sex for each tympanometric index. Correlation analyses examined the association between right and left ear indices. Interaural differences in tympanometric indices were examined with independent t-tests. Critical differences, for deciding if two tympanometric indices are different between ears, were computed from the standard deviations of the right–left ear difference for statistical confidence levels of 85, 90, 95, and 99%.
Results
The effect of ear was not statistically significant (p > 0.05) on any tympanometric index. Females had significantly lower Ytm and smaller Vea measures than males (p 0.05). Critical differences, for confidence levels for 85% to 99% confidence ranged from ± 0.20–0.36 mmhos for Ytm, ± 0.23–0.41 cm3 for Vea, ± 11.1–19.8 daPa for TPP, and ± 27.2–48.7 daPa for TW.
Conclusion
A clinician can use these critical differences to determine if tympanometric index interaural differences in ears of young normal Caucasian adults are statistically significant.DOI : 10.1055/s-0041-1722946|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=273015

Patrick Feeney Année de publication : 2021 Article en page(s) : p. 235-245 Note générale : DOI: 10.1055/s-0041-1723041 Langues : Anglais (eng) Descripteurs : HE Vinci
Accessibilité des services de santé ; Dépistage auditif ; Perte d'auditionRésumé : Background
The study examined follow-up rates for pursuing hearing health care (HHC) 6 to 8 months after participants self-administered one of three hearing screening methods: an automated method for testing of auditory sensitivity (AMTAS), a four-frequency pure-tone screener (FFS), or a digits-in-noise test (DIN), with and without the presentation of a 2-minute educational video about hearing.
Purpose
The study aims to determine if the type of self-administered hearing screening method (with or without an educational video) affects HHC follow-up rates.
Research Design
The study is a randomized controlled trial of three automated hearing screening methods, plus control group, with and without an educational video. The control group completed questionnaires and provided follow-up data but did not undergo a hearing screening test.
Study Sample
The study sample includes 1,665 participants (mean age 50.8 years; 935 males) at two VA Medical Centers and at university and community centers in Portland, OR; Bay Pines, FL; Minneapolis, MN; Mauston, WI; and Columbus, OH.
Data Collection and Analysis
HHC follow-up data at 6 to 8 months were obtained by contacting participants by phone or mail. Screening methods and participant characteristics were compared in relation to the probability of participants pursuing HHC during the follow-up period.
Results
The 2-minute educational video did not have a significant effect on HHC follow-up rates. When all participants who provided follow-up data are considered (n = 1012), the FFS was the only test that resulted in a significantly greater percentage of HHC follow-up (24.6%) compared with the control group (16.8%); p = 0.03. However, for participants who failed a hearing screening (n = 467), follow-up results for all screening methods were significantly greater than for controls. The FFS resulted in a greater probability for HHC follow-up overall than the other two screening methods. Moreover, veterans had higher follow-up rates for all screening methods than non-veterans.
Conclusion
The FFS resulted in a greater HHC follow-up rate compared with the other screening methods. This self-administered test may be more motivational for HHC follow-up because participants who fail the screening are aware of sounds they could not hear which does not occur with adaptive assessments like AMTAS or the DIN test. It is likely that access to and reduced personal cost of audiological services for veterans contributed to higher HHC follow-up rates in this group compared with non-veteran participants.DOI : 10.1055/s-0041-1723041|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=273016

Arabe (langue) ; Audiométrie vocale ; Evaluation auditive ; Reconnaissance auditive du motRésumé : Background
Many of the Arabic monosyllabic word lists that are currently available in the literature have some limitations and drawbacks. Some of these available lists include word structures that are not consonant-nucleus-consonant (CNC) such as cluster and disyllabic word structures. Other lists have poor phonetic or phonemic distribution balance and do not represent some phoneme appropriately in each list.
Purpose
The purpose of the present study is to create and validate eight digitally recorded lists of phonemically balanced CNC words that represent all Arabic phonemes, to be used in the evaluation of word recognition score (WRS) of Jordanian Arabic-speaking adults. These lists should be easily adapted by other Arab countries because of the simplicity of the words, and the balanced inclusion of all the Arabic phonemes.
Research Design
The present study is a prospective cross-sectional study.
Study Sample
Thirty-one (23 females, 8 males) normal hearing and healthy young adults (18–29 years old) participated in the present study. All participants were native speakers of Jordanian Arabic and had no history of ear disease or surgery.
Lists
The authors created all possible combinations of Arabic CNC words, and then created eight phonemically balanced lists with 26 words in each list. Each consonant was presented only once at the beginning of a word and once at the end of a word in each list. The lists were recorded using a Jordanian male voice and the intensity of each word was digitally calibrated.
Data Collection and Analysis
The pure tone average (PTA) of 0.5, 1, 2, 4 kHz was calculated for each participant, and the WRS was obtained for each intensity level in the range of –10 to 55 dB SL (ref. PTA) in 5 dB steps.
Results
No significant difference between right and left ear WRS was found at any intensity level. The WRSs from both ears were averaged and used in the repeated measure analysis of variance. Performance-intensity functions for all the lists showed some small but statistically significant differences between lists. However, none of these differences were clinically significant (
Conclusion
The present study provides eight lists of recorded and calibrated CNC word lists. The obtained PI functions showed that these lists are suitable for Jordanian Arabic speaking adults. These lists can be easily generalized to other Arab countries after conducting the required follow-up research.DOI : 10.1055/s-0041-1722986|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=273033

Titre : Contralateral Masking in the Measurement of Auditory Brainstem Responses with Air-Conducted Tone Burst Stimuli in Individuals with Unilateral Hearing Loss Type de document : Article Auteurs : Bárbara Cristiane Sordi Silva ; Lilian Cássia Bórnia Jacob-Corteletti ; Tyuana Sandim da Silveira Sassi ; Juliana Nogueira Chaves ; Eliene Silva Araújo ; Kátia de Freitas Alvarenga Année de publication : 2021 Article en page(s) : p. 254-260 Note générale : DOI: 10.1055/s-0041-1722985 Langues : Anglais (eng) Descripteurs : HE Vinci
Audiométrie tonale ; Masquage perceptif ; Perte auditive unilatérale (USNHL) ; Potentiels évoqués auditifs du tronc cérébral (ABR)Résumé : Background
Contralateral noise masking is an important aspect of auditory brainstem response (ABR) measurements.
Purpose
The primary aim of this study is to determine how contralateral white noise (WN) masking influences the amplitude and the latency of V wave generated during ABR measurements, using tone burst (TB), in adult ears with normal hearing (NH). The secondary aim of this study is to ascertain the need of contralateral masking in ABR measurements with the TB stimuli using a 3A insertion earphone, and to propose the applicability of WN masking in unilateral sensorineural hearing loss (USNHL).
Research Design
It is a cross-sectional observational and descriptive study.
Study Sample
Experiment 1: Thirty individuals, without any otologic, psychological, or neurological dysfunction, were selected. Experiment 2: Fifteen individuals with previous audiological diagnoses of severe and profound USNHL were considered.
Intervention
The study involves ABR TB at specific frequencies of 0.5, 1, 2, and 4 kHz.
Data Collection and Analysis
Experiment 1: The evaluation was performed at the fixed intensity of 80 dB nHL (decibel normalized hearing level) on the tested ear, followed by the application of simultaneous masking to the nontested ear, intensity ranged from 0 to 80 dB. Experiment 2: ABR threshold measurements were first performed on the ear with hearing loss (HL) at the frequencies of 1, 2, and 4 kHz. The results were subsequently confirmed using contralateral masking.
Results
Experiment 1: At any given frequency, there were no statistically significant differences in the amplitude and latency of V wave with increase in the intensities of WN masking. Experiment 2: Cross-hearing was observed at least once in all frequencies analyzed through the occurrence of V wave.
Conclusion
In conclusion, the contralateral WN masking at the maximum intensity of 80 dB does not affect the amplitude and latency of V wave of the ABR TB at 1, 2, and 4 kHz. Contralateral masking for the ABR TB presented using 3A insertion earphones is necessary at 1, 2, and 4 kHz in individuals with severe or profound degrees of USNHL and at intensities of 15, 20, and 10 dB above the ABR threshold of the nontested ear.DOI : 10.1055/s-0041-1722985|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=273034

Titre : Breaking Down Communication Barriers: Assessing the Need for Audiologists to Have Access to Clinically Relevant Sign Language Type de document : Article Auteurs : Samantha Panning ; Rachel L. Lee ; Sara M. Misurelli Année de publication : 2021 Article en page(s) : p. 261-267 Note générale : DOI: 10.1055/s-0041-1722988 Langues : Anglais (eng) Descripteurs : HE Vinci
Audiologues ; Langue des signes américaine (ASL)Mots-clés : Signes cliniques Culture sourde Résumé : Background
Research suggests Deaf individuals have longstanding negative perceptions of their interactions with health care providers, primarily due to communication barriers. One way to improve relations would be for audiologists to learn clinically relevant sign language.
Purpose
The aim of the study is to gain a better understanding of audiologists' knowledge of Deaf culture and American Sign Language (ASL) and evaluate motivation for instruction in signing abilities.
Research Design
A 21-question survey was emailed and advertised in a social media group for audiologists. The survey was divided into four sections: (1) demographics, (2) education of ASL and Deaf culture, (3) experience with ASL and Deaf culture, and (4) motivation to learn clinical signs.
Data Analysis
Descriptive statistics were analyzed for quantitative analysis of survey responses.
Results
A total of 489 responses were obtained and analyzed. Majority of respondents (82.6%) completed a manual ASL course, though only a third reported exposure to clinically relevant signs (37.4%). The majority of respondents rated their signing abilities at the word level, and knowing somewhere between 5 and 20 signs, expressively (50.5%) and receptively (53.9%). Results illustrate the majority of audiologists (54.5%) feel their clinical signing abilities need to be improved and were either highly (30.9%) or somewhat motivated (42.1%) to do so.
Conclusion
Study results suggest that although participants are enrolling in and completing ASL courses, clinical signs are not routinely included. This omission leads to reduced signing ability, potentially harming the provider–patient relationship. The majority of survey respondents reported that they are strongly motivated to improve their signing abilities. Results of the present study suggest there is need for a comprehensive clinical signs resource for audiologists to provide quality patient care to their Deaf patients. At present, there is no known, available tool to help accomplish this need.DOI : 10.1055/s-0041-1722988|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=273035

Qualite du son percuRésumé : Background
Emotional speech differs from neutral speech in its envelope characteristics. Use of emotional speech materials may be more sensitive for evaluating signal processing algorithms that affect the temporal envelope.
Purpose
Subjective listener preference was compared between variable speed compression (VSC) and fast acting compression (FAC) amplitude compression algorithms using neutral and emotional speech.
Research Design
The study used a single-blinded, repeated measures design.
Study Sample
Twenty hearing-impaired (HI) listeners with a bilaterally symmetrical, mild- to-moderately severe sensorineural hearing loss and 21 listeners with normal hearing (NH) participated.
Intervention
Speech was processed using FAC and VSC algorithms.
Data Collection and Analysis
A paired-comparison paradigm assessed subjective preference for FAC versus VSC using emotional and neutral speech materials. The significance of subjective preference for compression algorithm (FAC or VSC) was evaluated using a linear mixed effects model at each combination of stimulus type (emotional or neutral speech) and hearing group (NH or HI).
Results
HI listeners showed a preference for VSC over FAC when listening to emotional speech. The same listeners showed a nonsignificant, preference for VSC over FAC when listening to neutral speech. NH listeners showed preference for VSC over FAC for both neutral and emotional speech materials.
Conclusion
These results suggest that the subjective sound quality of emotional speech is more susceptible than neutral speech to changes in the signal introduced by FAC. Clinicians should consider including emotional speech materials when evaluating listener preference for different compression speeds in the clinic.DOI : 10.1055/s-0041-1722945|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=273036

Acceptable Noise Level (ANL) ; Electrocochléographie ; Potentiels microphoniques cochléairesRésumé : Background
The acceptable noise level (ANL) is a measurement used to quantify how much noise a person is willing to accept while listening to speech. ANL has been used to predict success with hearing aid use. However, physiological correlates of the ANL are poorly understood. One potential physiological correlate is the medial olivocochlear reflex (MOCR), which decreases the output of the cochlea and is thereby expected to increase noise tolerance.
Purpose
This study investigates the relationship between contralateral activation of the MOCR and tolerance of background noise.
Research Design
This study recruited 22 young adult participants with normal hearing. ANL was measured using the Arizona Travelogue recording under headphones presented at the most comfortable level (MCL) with and without multitalker babble noise. The MOCR strength was evaluated in all participants by measuring the cochlear microphonic (CM) with and without 40 dB sound pressure level contralateral broadband noise (CBBN).
Data Analysis
The CM observed in response to a 500-Hz tone was measured with and without CBBN, and changes in response to fast Fourier transform amplitude at 500 Hz were used as an indicator of the MOCR effect. The ANL was calculated by subtracting the maximum acceptable background noise level from the MCL. Participants were divided into two groups based on their ANL: low-ANL (ANL
Results
The results indicated that presentation of CBBN increased the CM amplitude, consistent with eliciting the MOCR. Participants in the low-ANL group had significantly larger CM enhancement than moderate-ANL participants. The results further revealed a significant correlation between the ANL and the MOCR effect on the CM.
Conclusion
This study suggests that a stronger MOCR, as assessed using CM enhancement, is associated with greater noise tolerance. This research provides a possible objective measure to predict background tolerance in patients and adds to our understanding about the MOCR function in humans.DOI : 10.1055/s-0040-1718705|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=272438

Implication psychosocialeRésumé : Background
Increasing numbers of adults are receiving cochlear implants (CIs) and many achieve high levels of speech perception and improved quality of life. However, a proportion of implant recipients still struggle due to limited speech recognition and/or greater communication demands in their daily lives. For these individuals a program of aural rehabilitation (AR) has the potential to improve outcomes.
Purpose
The study investigated the effects of a short-term AR intervention on speech recognition, functional communication, and psychosocial outcomes in post lingually deafened adult CI users.
Research Design
The experimental design was a multisite clinical study with participants randomized to either an AR treatment or active control group. Each group completed 6 weekly 90-minute individual treatment sessions. Assessments were completed pretreatment, 1 week and 2 months post-treatment.
Study Sample
Twenty-five post lingually deafened adult CI recipients participated. AR group: mean age 66.2 (48–80); nine females, four males; months postactivation 7.7 (3–16); mean years severe to profound deafness 18.4 (2–40). Active control group: mean age 62.8 (47–85); eight females, four males; months postactivation 7.0 (3–13); mean years severe to profound deafness 18.8 (1–55).
Intervention
The AR protocol consisted of auditory training (words, sentences, speech tracking), and psychosocial counseling (informational and communication strategies). Active control group participants engaged in cognitive stimulation activities (e.g., crosswords, sudoku, etc.).
Data Collection and Analysis
Repeated measures ANOVA or analysis of variance, MANOVA or multivariate analysis of variance, and planned contrasts were used to compare group performance on the following measures: CasperSent; Hearing Handicap Inventory; Nijmegen Cochlear Implant Questionnaire; Client Oriented Scale of Improvement; Glasgow Benefit Inventory.
Results
The AR group showed statistically significant improvements on speech recognition performance, psychosocial function, and communication goals with no significant improvement seen in the control group. The two groups were statistically equivalent on all outcome measures at preassessment. The robust improvements for the AR group were maintained at 2 months post-treatment.
Conclusion
Results of this clinical study provide evidence that a short-term AR intervention protocol can maximize outcomes for adult post lingually deafened CI users. The impact of this brief multidimensional AR intervention to extend CI benefit is compelling, and may serve as a template for best practices with adult CI users.DOI : 10.1055/s-0041-1722987|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=272448

Titre : Accuracy of an Automated Hearing Aid Fitting Using Real Ear Measures Embedded in a Manufacturer Fitting Software Type de document : Article Auteurs : Alison Brockmeyer ; Adam Voss ; Cameron C. Wick ; Nedim Durakovic ; Michael Valente Année de publication : 2021 Article en page(s) : p. 157-163 Note générale : DOI: 10.1055/s-0041-1722947 Langues : Anglais (eng) Descripteurs : HE Vinci
Aides auditives ; Mesure réelle de l'oreille (REM) ; PrécisionRésumé : Background
Hearing aid fitting guidelines recommend real ear measures (REM) to verify hearing aid performance. Unfortunately, approximately 70 to 80% of clinicians do not use REM, but instead download manufacturer first-fit. Studies report differences in performance between first-fit and programmed-fit with greatest differences in the higher frequencies. Recently, hearing aid and real ear analyzer (REA) manufacturers allow REA communication with hearing aid software feature to automatically program hearing aids to target. Little research is available reporting the accuracy of this feature.
Purpose
The aim of the study is to examine whether differences exist at 50, 65, and 80 dB SPL between two ReSound first-fit formulae (Audiogram+ and NAL-NL2) using ReSound AutoREM and Aurical NAL-NL2
Research Design
The study design is of repeated measure type.
Study Sample
The study sample includes 48 ears.
Data Collection and Analysis
For the two fitting formulae, AutoREM real ear insertion gain (REIG) was measured at 50, 65, and 80 dB SPL and compared with measures from Aurical NAL-NL2.
Results
Mean AutoREM REIG for ReSound NAL-NL2 was 3 to 8 dB below Aurical NAL-NL2 for 50 dB SPL, within 1 to 3 dB for 65 dB SPL and 1 to 5 dB above for 80 dB SPL. Mean AutoREM REIG for Audiogram + was 1 to 12 dB below Aurical NAL-NL2 for 50 dB SPL, within 2 to 5 dB for 65 dB SPL and 1 to 7 dB above NAL-NL2 for 80 dB SPL.
Conclusion
Relative to the Aurical NAL-NL2, AutoREM REIG50 for Audiogram + and ReSound NAL-NL2 was lower.

Changement acoustique complexe (ACC)Résumé : Purpose
The study is concern with the distinguishing of the stimuli containing high frequency information with the frequency compression feature at the cortical level using the acoustic change complex (ACC) and the comparison of such with the ACC answers of individuals with normal hearing.
Research Design
This is a case–control study.
Study Sample
Thirty adults (21 males and nine females) with normal hearing, ranging in age between 16 and 63 years (mean: 36.7 ± 12.9 years) and 20 adults (16 males and four females) with hearing loss ranging in age between 16 and 70 years (mean:49.0 ± 19.8 years) have been included in this study.
Data Collection and Analysis
A total of 1,000 ms long stimulus containing 500 and 4,000 Hz tonal stimuli was used for ACC recording. The start frequency (SF) and compression ratio (CR) parameters of the hearing aids were programmed according to the default settings (SFd, CRd) in the device software, the optimal setting (SFo, CRo), and the extra compression (SFe, CRe) requirements and ACC has been recorded for each condition. Evaluation has been performed according to P1-N1-P2 wave complex and ACC complex wave latencies. Independent samples t-test was used to test the significance of the differences between the groups.
Results
In all individuals ACC has been observed. There was a significant difference between the wave latencies in normal hearing- and hearing-impaired groups. All wave latency averages of the individuals with hearing impairment were longer than the individuals with normal hearing. There were statistically significant differences between SFd-SFo, SFd-SFe, and SFo-SFe parameters. But there was no difference between CRd, CRo, and CRe in terms of CRs.
Conclusion
In order to discriminate high frequency information at the cortical level we should not rely on default settings of the SF and CR of the hearing aids. Optimal bandwidth must be adjusted without performing insufficient compression or over-compression. ACC can be used besides the real ear measurement for hearing aid fitting.DOI : 10.1055/s-0041-1722948|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=272480

Resolution temporelleMots-clés : Modulation detection threshold (MDT) Résumé : Background
Temporal resolution is essential to speech acoustic perception. However, it may alter in individuals with auditory disorders, impairing the development of spoken and written language. The envelope of speech signals contains amplitude modulation (AM) that has critical information. Any problem reducing the listener's sensitivity to these amplitude variations (auditory temporal acuity) is likely to cause speech comprehension problems. The modulation detection threshold (MDT) test is a measure for evaluating temporal resolution. However, this test cannot be used for patients with poor cooperation; therefore, objective evaluation of MDT is essential.
Purpose
The main aim of this study is to find the association between the auditory steady-state response (ASSR) and psychoacoustic measurement of MDT at different intensity levels and to assess the amplitude and phase of ASSR as a function of modulation depth.
Design
This was a correlational research.
Study Sample
Eighteen individuals (nine males and nine females) with normal hearing sensitivity, aged between 18 and 23 years, participated in this study.
Data Collection and Analysis
ASSR was recorded at fixed AM rates and variable AM depths for carrier frequencies of 1,000 and 2,000 Hz with varying intensities. The least AM depth, efficient to evoke an ASSR response, was interpreted as the physiological detection threshold of AM. The ASSR amplitude and phase, as a function of AM depth, were also evaluated at an intensity level of 60 dB hearing level (HL) with modulation rates of 40 and 100 Hz. Moreover, the Natus instrument (Biologic Systems) was used for the electrophysiological measurements. An AC40 clinical audiometer (Intra-acoustic, Denmark) was also used for the psychoacoustic measurement of MDT in a similar setting to ASSR, using the two-alternative forced choice method. Pearson's correlation test and linear regression model and paired t-test were used for statistical analyses.
Results
A significant positive correlation was found between psychoacoustic and electrophysiological measurements at a carrier frequency of 1000 Hz, with a modulation rate of 40 Hz at intensity levels of 60 dB HL (r = 0.63, p = 0.004), 50 dB HL (r = 0.52, p = 0.02). A significant positive correlation was also found at a carrier frequency of 2000 Hz, with a modulation rate of 47 Hz at 60 dB HL (r = 0.55, p = 0.01) and 50 dB HL (r = 0.67, p = 0.002) and a modulation rate of 97 Hz at 60 dB HL (r = 0.65, p = 0.003). Moreover, a significant association was found between the modulation depth and ASSR amplitude and phase increment at carrier frequencies of 1,000 and 2000 Hz, with modulation rates of 40 and 100 Hz.
Conclusion
There was a significant correlation between ASSR and behavioral measurement of MDT, even at low intensities with low modulation rates of 40 and 47 Hz. The ASSR amplitude and phase increment was a function of modulation depth increase. The findings of this study can be used as a basis for evaluating the relationship between two approaches in the clinical population.DOI : 10.1055/s-0041-1722983|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=272483

Titre : Benefits of Bilateral Hearing on the Telephone for Cochlear Implant Recipients Type de document : Article Auteurs : Sharon E. Miller ; Jace Wolfe ; Mila Duke ; Erin Schafer ; Smita Agrawal ; Dawn Koch ; Sara Neumann Année de publication : 2021 Article en page(s) : p. 180-185 Note générale : DOI: 10.1055/s-0041-1722982 Langues : Anglais (eng) Descripteurs : HE Vinci
Bruit ; Implants cochléaires ; Reconnaissance de la parole ; TéléphoneRésumé : Background
Cochlear implant (CI) recipients frequently experience difficulty understanding speech over the telephone and rely on hearing assistive technology (HAT) to improve performance. Bilateral inter-processor audio streaming technology using nearfield magnetic induction is an advanced technology incorporated within a hearing aid or CI processor that can deliver telephone audio signals captured at one sound processor to the sound processor at the opposite ear. To date, limited data exist examining the efficacy of this technology in CI users to improve speech understanding on the telephone.
Purpose
The primary objective of this study was to examine telephone speech recognition outcomes in bilateral CI recipients in a bilateral inter-processor audio streaming condition (DuoPhone) compared with a monaural condition (i.e., telephone listening with one sound processor) in quiet and in background noise. Outcomes in the monaural and bilateral conditions using either a telecoil or T-Mic2 technology were also assessed. The secondary aim was to examine how deactivating microphone input in the contralateral processor in the bilateral wireless streaming conditions, and thereby modifying the signal-to-noise ratio, affected speech recognition in noise.
Research Design
A repeated-measures design was used to evaluate speech recognition performance in quiet and competing noise with the telephone signal transmitted acoustically or via the telecoil to the ipsilateral sound processor microphone in monaural and bilateral wireless streaming listening conditions.
Study Sample
Nine bilateral CI users with Advanced Bionics HiRes 90K and/or CII devices were included in the study.
Data Collection and Analysis
The effects of phone input (monaural [DuoPhone Off] vs. bilateral [DuoPhone on]) and processor input (T-Mic2 vs. telecoil) on word recognition in quiet and noise were assessed using separate repeated-measures analysis of variance. Effect of the contralateral device mic deactivation on speech recognition outcomes for the T-Mic2 DuoPhone conditions was assessed using paired Student's t-tests.
Results
Telephone speech recognition was significantly better in the bilateral inter-processor streaming conditions relative to the monaural conditions in both quiet and noise. Speech recognition outcomes were similar in quiet and noise when using the T-Mic2 and telecoil in the monaural and bilateral conditions. For the acoustic DuoPhone conditions using the T-Mic2, speech recognition in noise was significantly better when the microphone of the contralateral processor was disabled.
Conclusion
Inter-processor audio streaming allows for bilateral listening on the telephone and produces better speech recognition in quiet and in noise compared with monaural listening conditions for adult CI recipients.DOI : 10.1055/s-0041-1722982|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=272487

Balance dysfunction is a complex, disabling health condition that can present with multiple phenotypes and etiologies. Data regarding prevalence, characterization of dizziness, or associated factors is limited, especially in an African American population.
Purpose
The aim of the study is to characterize balance dysfunction presentation and prevalence in an African American cohort, and balance dysfunction relationship to cardiometabolic factors.
Research Design
The study design is descriptive, cross sectional analysis.
Study Sample
The study sample consist of N = 1,314, participants in the Jackson Heart Study (JHS).
Data Collection and Analysis
JHS participants were presented an initial Hearing health screening questionnaire (N = 1,314). Of these, 317 participants reported dizziness and completed a follow-up Dizziness History Questionnaire. Descriptive analysis was used to compare differences in the cohorts' social-demographic characteristics and cardiometabolic variables to the 997 participants who did not report dizziness on the initial screening questionnaire. Based on questionnaire responses, participants were grouped into dizziness profiles (orthostatic, migraine, and vestibular) to further examine differences in cardiometabolic markers as related to different profiles of dizziness. Logistical regression models were adjusted for age, sex, education, reported noise exposure, and hearing sensitivity.
Results
Participants that reported any dizziness were slightly older and predominantly women. Other significant complaints in the dizzy versus nondizzy cohort included hearing loss, tinnitus, and a history of noise exposure (p
Conclusion
Dizziness among African Americans is comparable to the general population with regards to age and sex distribution, accordingly to previously published estimates. Participants with dizziness symptoms appear to have significant differences in BMI and blood pressure regulation, especially with associated orthostatic or migraine type profiles; this relationship does not appear to be conserved in participants who present with vestibular etiology symptoms.DOI : 10.1055/s-0041-1722949|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=272491

Titre : Auditory Hallucinations : An Audiological Horizon ? Type de document : Article Auteurs : Frank E. Musiek ; Sarah Morris ; Kayla Ichiba ; Liza Clark ; Alyssa J. Davidson Année de publication : 2021 Article en page(s) : p. 195-210 Note générale : DOI: 10.1055/s-0041-1722989 Langues : Anglais (eng) Descripteurs : HE Vinci
Hallucination verbale ; Hallucinations auditives ; Illusions auditives ; Schizophrénie ; Troubles de l'audition centraleMots-clés : Hallucinations musicales Résumé : Background
Interesting data and theories have emerged regarding auditory hallucinations (AHs) in patients with schizophrenia. The possibility that these patients may have changes in the anatomy of the auditory cortex and/or subcortical structures of the central auditory nervous system and present with deficits on audiological tests is important information to the audiology community. However, it seems clear that, in general, audiologists are not sufficiently aware of these findings.
Purpose
There are two main purposes of this article: (1) to educate audiologists about AHs related to schizophrenia and related issues, and (2) to encourage audiologists and hearing scientists to become involved in the evaluation and research of AHs. This fascinating disorder is one in which audiologists/hearing scientists are well suited to make a significant contribution.
Research Design
A review and synthesis of the literature was conducted. Relevant literature was identified through PubMed, Google Scholar, as well as independent book chapters and article searches. Keywords driving the searches were AHs, auditory illusions, verbal and musical hallucinations, schizophrenia, and central auditory disorders. Given the currency of the topic, the information collected was primarily between 1990 and 2020.
Study Sample
The review is organized around categorization, prevalence, models, mechanisms, anatomy, pathophysiology, and audiological correlates related to AHs.
Data Collection and Analysis
Searches were conducted using well-known search engines and manual searches by each author. This information on AHs was then analyzed collectively by the authors for useful background and relevance, as well as important for the field of audiology.
Results
Several anatomical, physiological, and functional imaging studies have shown compromise of the auditory cortex in those with schizophrenia and AHs. Potentially related to this, are studies that demonstrated sub-par performance on behavioral audiologic measures for this unique clinical population. These findings align well with the kind of hearing disorder for which audiologists are well-trained to make significant contributions.
Conclusion
Neurobiological and audiological evidence is accumulating on patients with schizophrenia and AH potentially rendering it as both an auditory and psychiatric disorder. Audiologists should consider expanding their horizon and playing a role in the clinical investigation of this disorder.DOI : 10.1055/s-0041-1722989|1 Disponible en ligne : Oui/Non En ligne : https://login.ezproxy.vinci.be/login?url=https://medone-comsci.thieme.com/ejourn [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=272492
