Test de performanceRésumé : Background
Wideband absorbance (WBA) measured at ambient pressure (WBAA) does not directly account for middle ear pressure effects. On the other hand, WBA measured at tympanometric peak pressure (TPP) (WBATPP) may compensate for the middle ear pressure effects. To date, there are no studies that have compared WBAA and WBATPP in ears with surgically confirmed otitis media with effusion (OME).
Purpose
The purpose of this study was to compare the predictive accuracy of WBAA and WBATPP in ears with OME.
Research Design
Prospective cross-sectional study.
Study Sample
A total of 60 ears from 38 healthy children (mean age = 6.5 years, SD = 1.84 years) and 60 ears from 38 children (mean age = 5.5 years, SD = 3.3 years) with confirmed OME during myringotomy were included in this study.
Data Collection and Analysis
Results were analyzed using descriptive statistics and analysis of variance. The predictive accuracy of WBAA and WBATPP was determined using receiver operating characteristics (ROC) analyses.
Results
Both WBAA and WBATPP were reduced in ears with OME compared with that in healthy ears. The area under the ROC (AROC) curve was 0.92 for WBAA at 1.5 kHz, whereas that for WBATPP at 1.25 kHz was 0.91. In comparison, the AROC for 226-Hz tympanometry based on the static acoustic admittance (Ytm) measure was 0.93.
Conclusions
Both WBAA and WBATPP showed high and similar test performance, but neither test performed significantly better than 226-Hz tympanometry for detection of surgically confirmed OME.DOI : 10.3766/jaaa.19012|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=261779

Titre : Access to Hearing Health Care, Geographical Residency, and Quality of Life in Adults with and without Hearing Loss Type de document : Article Auteurs : Marcia Hay-McCutcheon ; Mildred Threadgill ; Xin Yang ; Frank Phillips Année de publication : 2020 Article en page(s) : p. 485-495 Langues : Anglais (eng) Descripteurs : HE Vinci
Accessibilité des services de santé ; Approche psychosociale ; Etude comparative ; Perte d'audition ; Qualité de vie ; Services à la personneRésumé : Background
There is an increased interest in the impact that hearing loss has on general well-being, including overall quality of life (QOL), to improve and expand care that is provided to individuals with hearing loss.
Purpose
To evaluate QOL in adults with and without access to hearing health care (HHC).
Research Design
A cross-sectional study examined QOL across groups of individuals with and without hearing loss.
Study Sample
One hundred eight participants from West Central and South Alabama received pure-tone hearing evaluations. Thirty-two adults had hearing within normal limits and 76 had at least a mild hearing loss in one ear.
Data Collection and Analysis
The Quality of Life Inventory (QOLI), the Charlson Comorbidity Index, and an Accessibility to Health Care questionnaire were administered to all participants. The QOLI outcomes were used as the dependent variable for the analysis of covariance (ANCOVA) statistical procedures.
Results
For adults with hearing loss who did not have access to HHC, lower QOL scores were reported compared with those with access to HHC, but this finding was not significant. Although ANCOVA results did not suggest QOL differences across geographical regions, effect size calculations indicated that adults with hearing loss who lived in the most rural regions of Alabama had lower reported QOL scores than their counterparts who had hearing within normal limits. Finally, those with higher incomes, who were older, and who had fewer physical disorders reported higher QOL than those with lower incomes, who were younger, and who had more physical ailments.
Conclusions
Adults with hearing loss who live in regions without access to HHC might be at risk for decreased QOL. A number of models for improving access to HHC will be necessary to decrease this potential risk.DOI : 10.3766/jaaa.19014|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=261787

Titre : Relationship of Head Circumference and Age in the Prediction of the Real-Ear-to-Coupler Difference (RECD) Type de document : Article Auteurs : Kelli M. Watts ; Marlene P.

Aides auditives ; Real ear to coupler difference (RECD) ; TêteMots-clés : Circonférence de la tête Résumé : Background
Pediatric hearing instrument fitting is optimally performed with individually obtained real-ear-to-coupler difference (RECD) measurements. If these measurements cannot be obtained, predicted values based on age are used. Recent evidence obtained from children aged 3–11 years suggests that head circumference (HC) may be a viable alternative or addition to age for use in RECD prediction.
Purpose
The purpose of the present study was to determine if HC can be used to predict RECDs in infants, children, and adults.
Research Design
A correlational design was used. HC and RECD values were measured in all participants.
Study Sample
Participants were 278 North American infants and children (136 males and 142 females) aged 1.6 months to 11 years and 109 adults (42 males and 67 females) aged 18 years to 83 years.
Data Collection and Analysis
After otoscopic inspection and immittance measurements were performed to assess candidacy for inclusion in the study, HC was measured twice for all participants and a single RECD measure was obtained for each participant at twelve frequencies (250 through 12500 Hz). The reliability of HC measurements was assessed with an intraclass correlation analysis. Linear regression analyses were performed with age and HC as predictor variables and RECDs as the dependent variable.
Results
indicated good reliability of the HC measurement. The relationships between RECD and HC were comparable with the relationships between RECD and age. Combining HC and age did not improve predictive accuracy.
Conclusions
HC can be used in children and adults as an alternative metric in the prediction of RECDs when individual RECDs cannot be obtained.DOI : 10.3766/jaaa.19017|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=261793

Microphone omnidirectionnelRésumé : Background
Despite improvements in cochlear implant (CI) technology, pediatric CI recipients continue to have more difficulty understanding speech than their typically hearing peers in background noise. A variety of strategies have been evaluated to help mitigate this disparity, such as signal processing, remote microphone technology, and microphone placement. Previous studies regarding microphone placement used speech processors that are now dated, and most studies investigating the improvement of speech recognition in background noise included adult listeners only.
Purpose
The purpose of the present study was to investigate the effects of microphone location and beamforming technology on speech understanding for pediatric CI recipients in noise.
Research Design
A prospective, repeated-measures, within-participant design was used to compare performance across listening conditions.
Study Sample
A total of nine children (aged 6.6 to 15.3 years) with at least one Advanced Bionics CI were recruited for this study.
Data Collection and Analysis
The Basic English Lexicon Sentences and AzBio Sentences were presented at 0o azimuth at 65-dB SPL in +5 signal-to-noise ratio noise presented from seven speakers using the R-SPACE system (Advanced Bionics, Valencia, CA). Performance was compared across three omnidirectional microphone configurations (processor microphone, T-Mic 2, and processor + T-Mic 2) and two directional microphone configurations (UltraZoom and auto UltraZoom). The two youngest participants were not tested in the directional microphone configurations.
Results
No significant differences were found between the various omnidirectional microphone configurations. UltraZoom provided significant benefit over all omnidirectional microphone configurations (T-Mic 2, p = 0.004, processor microphone, p
Conclusions
All omnidirectional microphone configurations yielded similar performance, suggesting that a child's listening performance in noise will not be compromised by choosing the microphone configuration best suited for the child. UltraZoom (adaptive beamformer) yielded higher performance than all omnidirectional microphones in moderate background noise for adolescents aged 9 to 15 years. The implications of these data suggest that for older children who are able to reliably use manual controls, UltraZoom will yield significantly higher performance in background noise when the target is in front of the listener.DOI : 10.3766/jaaa.19025|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=261798

Titre : Improving Acceptance of Background Noise with Sound Enrichment Type de document : Article Auteurs : Susan Gordon-Hickey ; Shelby Devis ; Leah Lewis ; James Van Haneghan Année de publication : 2020 Article en page(s) : p. 513-520 Langues : Anglais (eng) Descripteurs : HE Vinci
Acceptable Noise Level (ANL) ; Adaptation à l'aide auditive ; Background Noise Level (BNL) ; Bruit ambiant ; Jeune adulte (19-24 ans) ; Most Comfortable Listening Level (MCL)Résumé : Background
Acceptance of background noise serves as a means to predict likelihood of hearing aid success. Individuals that are able to accept background noise are more likely to be successful with hearing aids.
Purpose
The aim of the study was to assess the impact of sound enrichment on the acceptable noise level (ANL).
Study Sample
Nineteen young adult participants served as listeners. Participants were randomly assigned to the experimental or control group.
Research Design
An experimental design with random assignment to experimental or control group was used.
Data Collection and Analysis
One group used sound enrichment procedures for 2 weeks, whereas the other group served as a control group. Sound enrichment procedures required that participants add low-level background sound to any quiet environment encountered during the study. Most comfortable listening level (MCL) and background noise level (BNL) were measured at three sessions, each 1 week apart (baseline, after 1 week of treatment, and after 2 weeks of treatment).
Results Analytical
statistics revealed that ANL improved for the sound enrichment group but remained the same for the control group. For both groups, there was no significant change in MCL across sessions. However, for the experimental group, BNL improved (increased) over the 2-week period while using sound enrichment.
Conclusions
Results of this study indicate that ANL can be improved with the use of sound enrichment procedures over a 2-week period. Future work should examine the use of sound enrichment procedures for older adults with hearing loss.DOI : 10.3766/jaaa.19028|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=261811

Locuteur multipleRésumé : Although numerous studies have examined regional and racial–ethnic labeling of talker identity, few have evaluated speech perception skills of listeners from the southern United States.
The objective of the study was to examine the effect of competition, signal-to-noise ratio (SNR), race, and sex on sentence recognition performance in talkers from the Southern American English dialect region.
Design A four-factor mixed-measures design was used.
Sample Forty-eight normal-hearing young African American and White adults participated.
The Perceptually Robust English Sentence Test Open-set was used in quiet and in continuous and interrupted noise and multitalker babble at SNRs of −10, −5, 0, and 5 dB.
Significant main effects of competition (p Although African American English and White American English talkers living in the same geographic region demonstrate differences in speech production, their speech perception in noise does not appear to differ under the conditions examined in this study.DOI : 10.3766/jaaa.19029|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=262051

Audition normaleRésumé : English materials for speech audiometry are well established. In Spanish, speech-recognition materials are not standardized with monosyllables, bisyllables, and trisyllables used in word-recognition protocols.
This study aimed to establish the psychometric characteristics of common Spanish monosyllabic, bisyllabic, and trisyllabic words for potential use in word-recognition procedures.
Prospective descriptive study.
Eighteen adult Puerto Ricans (M = 25.6 years) with normal hearing [M = 7.8-dB hearing level (HL) pure-tone average] were recruited for two experiments.
A digital recording of 575 Spanish words was created (139 monosyllables, 359 bisyllables, and 77 trisyllables), incorporating materials from a variety of Spanish word-recognition lists. Experiment 1 (n = 6) used 25 randomly selected words from each of the three syllabic categories to estimate the presentation level ranges needed to obtain recognition performances over the 10 to 90% range. In Experiment 2 (n = 12) the 575 words were presented over five 1-hour sessions using presentation levels from 0- to 30-dB HL in 5-dB steps (monosyllables), 0- to 25-dB HL in 5-dB steps (bisyllables), and −3- to 17-dB HL in 4-dB steps (trisyllables). The presentation order of both the words and the presentation levels were randomized for each listener. The functions for each listener and each word were fit with polynomial equations from which the 50% points and slopes at the 50% point were calculated.
The mean 50% points and slopes at 50% were 8.9-dB HL, 4.0%/dB (monosyllables), 6.9-dB HL, 5.1%/dB (bisyllables), and 1.4-dB HL, 6.3%/dB (trisyllables). The Kruskal–Wallis test with Mann–Whitney U post-hoc analysis indicated that the mean 50% points and slopes at the 50% points of the individual word functions were significantly different among the syllabic categories. Although significant differences were observed among the syllabic categories, substantial overlap was noted in the individual word functions, indicating that the psychometric characteristics of the words were not dictated exclusively by the syllabic number. Influences associated with word difficulty, word familiarity, singular and plural form words, phonetic stress patterns, and gender word patterns also were evaluated.
The main finding was the direct relation between the number of syllables in a word and word-recognition performance. In general, words with more syllables were more easily recognized; there were, however, exceptions. The current data from young adults with normal hearing established the psychometric characteristics of the 575 Spanish words on which the formulation of word lists for both threshold and suprathreshold measures of word-recognition abilities in quiet and in noise and other word-recognition protocols can be based.DOI : 10.1055/s-0040-1709446|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=262057

Titre : Bilateral Cochlear Implants Allow Listeners to Benefit from Visual Information When Talker Location is Varied Type de document : Article Auteurs : Michael F. Dorman ; Sarah Natale ; Alissa Knickerbocker Année de publication : 2020 Article en page(s) : p. 547-550 Langues : Anglais (eng) Descripteurs : HE Vinci
Audition ; Implant cochléaire bilatéral ; Implants cochléairesRésumé : Background
Previous research has found that when the location of a talker was varied and an auditory prompt indicated the location of the talker, the addition of visual information produced a significant and large improvement in speech understanding for listeners with bilateral cochlear implants (CIs) but not with a unilateral CI. Presumably, the sound-source localization ability of the bilateral CI listeners allowed them to orient to the auditory prompt and benefit from visual information for the subsequent target sentence.
Purpose
The goal of this project was to assess the robustness of previous research by using a different test environment, a different CI, different test material, and a different response measure.
Research Design
Nine listeners fit with bilateral CIs were tested in a simulation of a crowded restaurant. Auditory–visual (AV) sentence material was presented from loudspeakers and video monitors at 0, +90, and −90 degrees. Each trial started with the presentation of an auditory alerting phrase from one of the three target loudspeakers followed by an AV target sentence from that loudspeaker/monitor. On each trial, the two nontarget monitors showed the speaker mouthing a different sentence. Sentences were presented in noise in four test conditions: one CI, one CI plus vision, bilateral CIs, and bilateral CIs plus vision.
Results
Mean percent words correct for the four test conditions were: one CI, 43%; bilateral CI, 60%; one CI plus vision, 52%; and bilateral CI plus vision, 84%. Visual information did not significantly improve performance in the single CI conditions but did improve performance in the bilateral CI conditions. The magnitude of improvement for two CIs versus one CI in the AV condition was approximately twice that for two CIs versus one CI in the auditory condition.
Conclusions
Our results are consistent with previous data showing the large value of bilateral implants in a complex AV listening environment. The results indicate that the value of bilateral CIs for speech understanding is significantly underestimated in standard, auditory-only, single-speaker, test environments.DOI : 10.1055/s-0040-1709444|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=262417
