Résumé
Apart from Von Békésy's traveling wave theory, this paper introduces our new comprehension on auditory system based on acoustic resonance in hair cells. Focusing on a rootlet inductance L and a membrane capacitance C of the hair cell, a real-sized cell model is designed so as to form a series LC resonant circuit for the incident soundwaves. In simulation, acoustic resonance is observed successfully at 1120 Hz together with 148-times sound pressure enhancement inside the cell. This model is useful to explain OAE responses, frequency shifts of absolute pitch for aging, pure-tone tinnitus, and even apoptosis of outer hair cells by huge sound exposure.
