Abstract :
The fully implantable hearing devices (FIHDs) have been widely studied to solve the problems of conventional hearing aids. The microphone of FIHDs is implanted under the skin at temporal bone. So, it´s characteristics can be affected by bone-conducted noise, such as chattering teeth and eating food. In this paper, we investigated the effect of bone-conducted noise on implanted microphone. To verify the noise effect, we implemented the physical model using the artificial bone and silicone. And a result, it confirmed that output signals are modified by bone-conducted signal.
