| Outline of Final Research Achievements |
We proposed an implanted bone conduction hearing aid to be worn in the crown of a dental implant. In this study, we measured the thresholds of bone conduction hearing via the teeth by using a bone conductive actuator. It was found that the thresholds of bone conduction hearing via the lower teeth tend to be louder than those of the upper teeth. In addition, it was found that bone conductive sounds tend to be louder when earplugs are used in both ears, even in a high S/N environment. This work studies wireless control between an implanted bone conduction hearing aid and an external microphone. Wireless control can be divided into three distinct types: Bluetooth, magnetic induction, and intrabody communication.
