Abstract
The dynamic characteristics of human ossicle responses to stimulus frequencies of 125 Hz, 250 Hz, 500 Hz, 750 Hz, 1 kHz, 2 kHz, 3 kHz, 4 kHz, 5 kHz, 6 kHz, 7 kHz and 8 kHz were analyzed using a 3D image model that was constructed using the finite element method. The 3D image model of the ossicle chain was based on images previously obtained from high-resolution computed tomography (CT) scans of the middle ear region of patients. The displacement at the footplate in the 3D model showed essentially no response when the ossicles were subjected to sound stimuli with frequencies above 2 kHz. However, the ossicles responded to sound stimuli with frequencies below 1 kHz, and the vibration of the ossicles was equivalent to the amplitude of the sound stimuli.
