Otoacoustic Emissions in Sudden Sensorineural Hearing Loss
... David Kemp in 1978 described some types of sound waves of cochlear origin which can be detected with a microphone in the external auditory canal. Since then, many studies have been performed in the clinical applicability of these “emissions” named “otoacoustic emissions (OAEs)”.Out of the various ty ...
