Abstract

Vibration of human tympanic membrane induced by sound is transmitted to a cochlea via auditory ossicles and stimulates an auditory nerve. Therefore, detailed study of the vibration of auditory ossicles is necessary to elucidate mechanisms of human hearing. In the present study, the sound-induced vibration of auditory ossicles is analyzed numerically by means of multibody dynamics. Numerical model of auditory ossicles is created precisely by using pictures of computerized axial tomography scan. Vibrational responses of auditory ossicles and force transmitted to a cochlea are calculated with stimuli from 1 to 10 kHz.
