Abstract

Acoustic signal processing in the central auditory system is determined by what the cochlea’s output to the auditory nerve contains. Once we understand signal preprocessing in the auditory periphery better evaluation of central processing is possible. In this respect, distortion-product otoacoustic emissions (DPOAE) are a beneficial tool of audiological investigation. Use of acoustically simple signals like pure tones enables nonlinear signal processing in the cochlea to be characterized. Measurements of DPOAE can demonstrate a great many interesting properties which are caused by both physiological and morphological behaviour of the cochlea.
