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 fro[...]Article
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[...]Article
Hammam A. AlMakadma, Auteur ; Joseph Kei, Auteur ; David Yeager, Auteur ; M. Patrick Feeney, Auteur |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 tympa[...]Article
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 1[...]Article
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 measu[...]Article
Objectives: Wideband absorbance (WBA) is an emerging technology to evaluate the conductive pathway (outer and middle ear) in young infants. While a wealth of research has been devoted to measuring WBA at ambient pressure, few studies have invest[...]Article
Cerys Downing, Auteur ; Joseph Kei, Auteur ; Carlie Driscoll, Auteur |Objective This study established a normative range of resonance frequency (RF) values as estimated using Wideband Tympanometry (WBT) and determined the ability of WBT-estimated RF to predict the presence of middle ear dysfunction in school-ag[...]Article
Background: Diagnosing conductive conditions in newborns is challenging for both audiologists and otolaryngologists. Although high-frequency tympanometry (HFT), acoustic stapedial reflex tests, and wideband absorbance measures are useful diag[...]Article
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 [...]Article
To study the developmental characteristics of sweep frequency impedance (SFI) measures in healthy infants from birth to 6 months. Design: All infants were assessed using high-frequency tympanometry (HFT), distortion product otoacoustic emission [...]Article
Hammam A. AlMakadma, Auteur ; Sreedevi Aithal, Auteur ; Venkatesh Aithal, Auteur ; Joseph Kei, Auteur |With widespread agreement on the importance of early identification of hearing loss, universal newborn hearing screening (UNHS) has become the standard of care in several countries. Despite advancements in screening technology, UNHS and early he[...]Article
Objectives The objective of this study was to describe wideband absorbance (WBA) findings in patients with cholesteatomas and retraction pockets (RPs). Design In this prospective study, tympanometry, audiometry, and wideband tympanometry (W[...]Article
Objectives : The objective of the present study was to describe pressurized wideband absorbance at tympanometric peak pressure (WBATPP) and 0 daPa (WBA0) in healthy Caucasian neonates. Subjects : A total of 249 ears from 249 neonates who passed [...]
