| Outline of Final Research Achievements |
Bone-conducted ultrasound (BCU) can be perceived even by the profoundly hearing impaired who cannot use conventional hearing aids. However, mechanisms of the BCU perception, especially the peripheral mechanisms remain unclear. In order to obtain useful information for the development of a novel hearing aid for the profoundly hearing impaired using BCU, we investigated the mechanisms of BCU perception from the periphery to the central nervous system. Psychological characteristics, neurophysiological responses, and the wave propagation property in the inner head were measured. Also, based on results of these measurements, the perception model of BCU perception was proposed. The results obtained provide useful information to optimize the BCU hearing aid and to establish its application guideline.
