ACOUSTIC SELECTIVITY OF INNER-EAR AND ACT IVE CONTROL OF RESONATORS

Recent discovery of vibration sources in the cochlea might lead to imp rovement of the classical acoustic cochlear models, which prove inadeq uate with regard to the high selectivity measured in the ear. In this respect, active control could give interpretations of active source wo rk. Thus, a control of gain is proposed to increase reaction speed of a harmonic oscillator. Physical interpretation and nonlinear effects o f the control are discussed as cochlear mechanisms.
