[Age-specific changes of evoked otoacoustic emission of different classes].
In different age groups of healthy subjects we registered two classes of evoked otoacoustic emission (OAE): delayed evoked OAE and OAE at the frequency of fault product. The findings show progressive decline of the amplitude of the otoacoustic response in subjects aged over 30-40 years. It is evident that sensor cells of Corti's organ may alter as early as over 30 years of age.
