Otoacoustic emission audiometry in neonates and adults

: The authors discuss the clinical use of the otoacoustic emission audiometry. During the physiological process of sound amplification in the cochlea vibration energy escapes from the inner ear. By the analysis of this sound it is possible to gain information about the function of the cochlea. According to the experiences of the authors the method is extremely useful for screening audiometry in pathological and normal neonates. In adults it can be used for monitoring the cochlear function during ototoxic therapy or noise exposure.
