The relationship between ultra-high frequency thresholds and transient evoked otoacoustic emissions in adults with tinnitus
Background: The possible role of cochlear function in tinnitus generation is still a matter of debate. To assess the role of outer hair cell dysfunction in tinnitus and its possible relationship with ultra-high frequency (UHF) hearing sensitivity, transient evoked otoacoustic emissions (TEOAE) and UHF hearing thresholds were investigated in normal hearing individuals with and withou...
متن کاملEvaluation 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 (...
متن کاملThe effects of aging on evoked otoacoustic emissions and efferent suppression of transient evoked otoacoustic emissions.
OBJECTIVE There is still controversy regarding the effects of aging on evoked otoacoustic emissions (EOAEs), as well as on the efferent system measured by contralateral acoustic stimulation of EOAEs. The purpose of this study was to investigate the deterioration in EOAEs and efferent suppression (ES) in a representative sample statistically controlling for the differences in hearing thresholds....
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 کاملOtoacoustic Emission in Tinnitus Patients
The purpose of the study was to determine the effect of tinnitus and total effect of tinnitus and the hearing loss function on the distortion product otoacoustic emission. Tinnitus patients were selected to exhibit normal hearing and such tinnitus patients who exhibited the increasing or notch-like sensorineural hearing loss. It was found that the cochlear hearing activity expressed in terms of...
