Outline of Final Research Achievements

The center of pressure of hearing aid users was measured in an anechoic room. The sway area and velocity improved with auditory cues. The maximum mediolateral displacement did not change in hearing aid users. The maximum velocity in mediolateral axis did differ between hearing aid users and normal hearing participants.
In cochlear implant users, the sway area and velocity was not affected by auditory cues. The center of pressure shifted laterally in silent condition with their eyes closed. This abnormal shift was eliminated with sound.

Academic Significance and Societal Importance of the Research Achievements

本研究によって聴覚入力は複数の機序を介して平衡機能に影響することが示された。この結果はあくまで無響室におけるものであり、現在の補聴器や人工内耳を用いた聴覚補償が現実世界においても同様に影響するとは限らない。ヴァーチャルリアリティーの技術を利用して平衡覚にも寄与しやすいように補聴器や人工内耳の調整を行うことで、日常生活でも聴覚補償が平衡覚の改善に有効となる可能性を示唆している。
