[The nature of fluctuations in spontaneous otoacoustic emission].
The nature of fluctuations of sound pressure during spontaneous otoacoustic emission is studied. The phenomenological mechanism of realization of positive feedback in cochlear is proposed. It is based on usage of hair cells ionic channels. By means of this model it is shown that spontaneous emission fluctuations are determined with thermal oscillations. The mass of the vibrating part of the basilar membrane, its dimensions and elasticity are calculated.
