Otoacoustic emission as an objective hearing test tool

Otoacoustic emission latency and hearing loss

Millions of people have the perception of sounds when no external sound is present: for many of them the“TINNITUS” (medical word from Latin) or “ACUFENE” (from Greek) is the trouble so severe to alter their quality of lifedeeply. Starting from 1998 we are carrying on with success an integral program of diagnosis, medical and rehabilitant treatment of the Tinnitus with a new multi therap...

Contralateral Suppression of Otoacoustic Emissions: Working Towards a Simple Objective Frequency Specific Test for Hearing Screening

Evaluation of Distortion and Transient Evoked Otoacoustic Emission in Tinnitus Patients with Normal Hearing

Introduction: Tinnitus is a perception of sound without external source. The exact etiology of tinnitus is not fully understood, although some researchers believe that the condition usually starts in the cochlea. The aim of this study was to determine the potential contribution of outer hair cell dysfunction to chronic tinnitus, by application of Distortion-Product Evoked Otoacoustic Emission (...

A cochlear-bone wave can yield a hearing sensation as well as otoacoustic emission

A hearing sensation arises when the elastic basilar membrane inside the cochlea vibrates. The basilar membrane is typically set into motion through airborne sound that displaces the middle ear and induces a pressure difference across the membrane. A second, alternative pathway exists, however: stimulation of the cochlear bone vibrates the basilar membrane as well. This pathway, referred to as b...

RR840 - Optimum test conditions and variability of otoacoustic emission testing in individuals with normal hearing

This study investigates issues important for the potential usefulness and practical application of OAE testing within an occupational health surveillance programme. Before this technique can be used within health surveillance, it is important to understand how reliable the measurements are and the level of change that could be detected over time within individuals. As any test of hearing functi...
