Clinical Forum: Otoacoustic Emissions, Audiometric Sensitivity Loss, and Speech Understanding: A Case Study
The clinical measurement of otoacoustic emissions can assist in differentiating between peripheral and central explanations for deficits in speech understanding. We present audiometric and distortion-product emission data in a case with sensorineural hearing loss and a deficit in speech understanding . The presence of evoked emissions argues against attributing the speech audiometric loss to co...
متن کاملBasilar-membrane Activity and Loudness
Buus and Florentine (ISP meeting 2001) presented evidence that basilar-membrane velocity growth functions are proportional to the square root of loudness functions derived from temporal and spectral integration. Although it is not possible to directly measure basilarmembrane activity in humans, it is likely that tone-burst otoacoustic emission input-output functions, at least at low and moderat...
متن کاملTechnical report: distortion product otoacoustic emissions that are not outer hair cell emissions.
PURPOSE To present a case study in order to alert clinicians to the possibility of occurrence of intermodulation distortion during otoacoustic emissions testing that arises from the cavity formed by the external auditory meatus and tympanic membrane rather than from the inner ear, compromising the reliability and validity of otoacoustic emissions testing. RESEARCH DESIGN Prospective case stud...
متن کاملMechanisms of mammalian otoacoustic emission and their implications for the clinical utility of otoacoustic emissions.
We review recent progress in understanding the physical and physiological mechanisms that generate otoacoustic emissions (OAEs). Until recently, the conceptual model underlying the interpretation of OAEs has been an integrated view that regards all OAEs as manifestations of cochlear nonlinearity. However, OAEs appear to arise by at least two fundamentally different mechanisms within the cochlea...
متن کاملTransient Evoked and Distortion Product Otoacoustic Emissions in a Group of Neonates
Introduction The most commonly used method in neonatal hearing screening programs is transient evoked otoacoustic emissions in the first stage of the process. There are few studies comparing transient evoked otoacoustic emissions with distortion product, but some authors have investigated the issue. Objective To correlate the results of transient evoked and distortion product otoacoustic emissi...
