Effects of GSM-like radiofrequency on distortion product otoacoustic emissions in pregnant adult rabbits.

Study of the hearing in children born from pregnant women exposed to occupational noise: Assessment by distortion product otoacoustic emissions Summary

Technical 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...

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 (...

The E ect of Amplitude Modulated Contralateral Signals on Distortion Product Otoacoustic Emissions

Contralateral stimulation of the auditory system causes changes in levels of otoacoustic emissions. The main objective of this study was to determine the changes in the level of distortion product otoacoustic emissions for contralaterally presented unmodulated broad-band noise, or amplitude modulated broad-band noise. Two types of modulating signal were used in the investigations (sine or recta...

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...
