Absorbance acoustique ; Conduit auditif externe (CAE) ; Oreille moyenne ; TympanométrieRésumé : The study investigated the effect of ear canal pressure and age on wideband absorbance (WBA) in healthy young infants.
Design: Using a cross-sectional design, WBA at 0.25 to 8?kHz was obtained from infants as the ear canal pressure was swept from?+200 to ?300 daPa. Study sample: The participants included 29 newborns, 9 infants each at 1 and 4 months and 11 infants at 6 months of age who passed distortion product otoacoustic emissions test. Results: In general, negative-ear canal pressures reduced WBA across the frequency range, while positive-ear canal pressures resulted in reduced WBA from 0.25 to 2?kHz and above 4?kHz with an increase in absorbance between 2 and 3?kHz compared to WBA at ambient pressure. The variation in WBA below 0.5?kHz, as the pressure was varied, was the greatest in newborns. But, the variation was progressively reduced in older infants up to the age of 6 months, suggesting stiffening of the ear canal with age. Conclusions: Significant changes in WBA were observed as a function of pressure and age. In particular, developmental effects on WBA were evident during the first six months of life.Accès : Contactez la bibliothèque d'Ixelles si le lien vers la ressource électronique ne fonctionne plus Disponible en ligne : Oui En ligne : https://login.ezproxy.vinci.be/login?url=https://www.tandfonline.com/doi/pdf/10.

Absorbance acoustique ; Dysfonctionnement tubaire ; Trompe d'eustache ; TympanométrieRésumé : Bien que l' absorbance large bande (WBA) fournit des informations importantes sur le fonctionnement de l' oreille moyenne, il y a peu de recherches sur l'utilisation de WBA pour évaluer la dysfonction tubaire (ETD). À ce jour, WBA obtenu sous la condition sous pression n'a pas été utilisé pour évaluer ETD.
L'objectif de l'étude était de comparer WBA à 0 conditions daPa et pression maximale tympanométriques (TPP) dans les oreilles en bonne santé et les oreilles avec ETD.
Une conception étude transversale a été utilisée.
Un total de 102 A oreilles en bonne santé de 79 participants (âge moyen = 10,0 an) et 43 de l'oreille 32 patients avec ETD (âge moyen = 16,0 ans) ont été inclus dans cette étude en coupe transversale. WBA a été mesurée à 0 daPa (WBA 0 ) et TPP WBA au TPP (WBATPP ).
les résultats WBA ont été analysées à l' aide des statistiques descriptives et t -Tests avec la correction de Bonferroni. Une analyse de la variance des mesures répétées a été appliquée aux données.
WBA 0 était significativement plus faible dans le groupe ETD que dans le groupe témoin. La WBA 0 du groupe de contrôle montré un large pic entre 1,25 et 4 kHz, alors que la WBA 0 du groupe ETD a un pic compris entre 2,5 et 4 kHz. WBA TPP du groupe ETD approché des valeurs proches de celle du groupe témoin. Dans le groupe témoin, WBA TPP était seulement 0,06 à 0,09 supérieur à WBA 0, Alors que dans le groupe ETD, WBA TPP est 0,29 à 0,42 plus élevé que WBA 0 compris entre 0,6 et 1,5 kHz. Un motif différentiel de WBA au TPP par rapport à 0 daPa n'a été observée entre les oreilles et les oreilles avec ETD avec otite moyenne avec épanchement (OME) et de l'oreille moyenne pression négative (NMEP).DOI : 10.3766/jaaa.18002|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=247360

Immitance acoustiqueRésumé : Assessment of middle ear impedance using noninvasive electroacoustic measurements has undergone successive developments since its first clinical application in the 1940s, and gained widespread adoption since the 1970s in the form of 226-Hz tympanometry, and applications in multifrequency tympanometry. More recently, wideband acoustic immittance (WAI) is allowing unprecedented assessments of the middle ear acoustic mechanics thanks to the ability to record responses over a wide range of frequencies. The purpose of this article is to present fundamental concepts for the assessment and interpretation of wideband measures, including a review of acoustic impedance and its relation to the mass, stiffness, and resistance components of the middle ear. Additionally, an understanding of the middle ear transfer function reveals the relationship between impedance and middle-ear gain as a function of frequency. Wideband power absorbance, a WAI measure, quantifies the efficiency of sound conduction through the middle ear over a wide range of frequencies, and can serve as an analogous clinical measure to the transfer function. The interpretation of absorbance measures in ears with or without a conductive condition using absorbance measured at ambient pressure and pressurized conditions (wideband tympanometry) is described using clinical case examples. This article serves as an introduction to the fundamental principles of WAI measurements.

Dépistage auditif de l'enfant ; Troubles de l'apprentissageRésumé : This study aimed to investigate hearing and auditory processing ability in primary school children with learning difficulties (LD).
A nonrandomized, cross-sectional single measure research design was used. A total of 486 children, aged 7.7 to 10.8 years and attending years 3 and 4 in six primary schools, were classified as having an LD (n = 67) or being typically developing (TD, n = 419). This classification was based on a Learning Score generated from their school report results and National Assessment Program Literacy and Numeracy scores. All children attempted a conventional hearing assessment (CHA) involving pure-tone audiometry, tympanometry, acoustic reflexes (AR), and otoacoustic emissions (OAEs). Children returning pure-tone audiometry results within normal limits also attempted an auditory processing assessment (APA) including dichotic digits (DD) and low-pass filtered speech (LPFS) tests.DOI : 10.1097/AUD.0000000000000652|1 Disponible en ligne : Oui En ligne : https://login.ezproxy.vinci.be/login?url=http://ovidsp.ovid.com/ovidweb.cgi?T=JS [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=251867

Difficulté d'apprentissage ; Trouble du traitement de l'information auditive (CAPD)Résumé : Objective: The current study examined the relationship between learning and auditory processing (AP) ability in a clinical sample of children with and without learning difficulties (LD).
Design: A non-randomised, cross-sectional, single measure research design was used.
Study sample: The participants consisted of 50 children (7.710.8 years) who had been referred for a clinical AP assessment based on having been referred from a school-based AP screening. These children had previously been identified as having (n = 14) or not having (n = 36) LD.
Results: Children with LD performed significantly worse than children without LD on frequency patterns with linguistic reports (FPlinR and FPlinL), dichotic digits (DD) and Auditory Word Memory Forward (ANMF) tests, with significant correlations being observed between these variables and the learning score. The multiple linear regression showed that FPlinR, DDR and ANMF scores explained 50% of the variance in the learning score.
Conclusion: The present studys results are most consistent with risk factor models linking AP to learning abilities in children where reduced AP abilities could put children at greater risk for LD. Further investigations into the potential relationships between AP, cognition, speech and language development, and learning ability in children are warranted.Accès : Contactez la bibliothèque d'Ixelles si le lien vers la ressource électronique ne fonctionne plus Disponible en ligne : Oui En ligne : https://login.ezproxy.vinci.be/login?url=https://www.tandfonline.com/doi/pdf/10.
