| Outline of Final Research Achievements |
In this study, I focused on the bone conduction through the teeth, I have proposed a new communication aid. Driving the teeth which is a part of the bone directly, it can be a very effective means for improving its performance in terms of both characteristics and efficiency. I developed small mouthpiece type tooth bone conduction device, which is adaptable to a variety of tooth type. I also evaluated the listening characteristics focused on articulation. It was shown that it is enough to be used as a new sound signaling pathways. In addition, I proposed the speech information acquisition using the mouthpiece type tooth bone conduction device, and showed that it is possible to obtain the clear sound even in noisy. Furthermore, in addition to improvements of the device in wireless radio, it was easy to mount and carry.
