Sex differences in distortion-product and transient-evoked otoacoustic emissions compared.

Although several studies have documented the existence of sex differences in spontaneous otoacoustic emissions (SOAEs) and transient-evoked OAEs (TEOAEs) in humans, less has been published about sex differences in distortion-product OAEs (DPOAEs). Estimates of sex and ear differences were extracted from a data set of OAE measurements previously collected for other purposes. In accord with past ...

The role of intermodulation distortion in transient-evoked otoacoustic emissions.

Transient-evoked otoacoustic emissions (TEOAEs) are low-intensity sounds recorded in the external ear canal immediately following stimulation by a transient stimulus, typically a click. While the details of their production is unknown, there is evidence to suggest that the amplitude of each component frequency reflects the physiological condition of the corresponding region of the cochlea. Cert...

Transient 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...

Transient evoked and distortion product otoacoustic emissions in traumatic brain injury.

Behavioral audiometry may be of limited value for those patients who have incurred significant brain injury and remain unresponsive to auditory stimuli. Even the more "objective" tests such as auditory brainstem response (ABR) and acoustic reflex testing may be inadequate tools to assess peripheral auditory function when significant brainstem injury has occurred. Determination of peripheral hea...

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 (...
