Outline of Annual Research Achievements

骨伝導で呈示された超音波であれば,最重度難聴者にも知覚されるが,そのメカニズムの詳細は明らかにされていない.本提案課題では,聴覚末梢器の活動を反映する各種の生理反応の計測,および骨導超音波の頭部内伝搬特性や末梢聴覚器に生成される振動モードの推定に取り組み,得られた知見から骨導超音波知覚の末梢知覚モデルを提案する.骨導超音波知覚のメカニズムの全貌を明らかにすることで,重度難聴者のための新型補聴器(骨導超音波補聴器)の開発に有用な知見の獲得を図ることを目的とする.2014年度は以下のような研究に取り組んだ.
1. 蝸電図計測による基底膜運動,有毛細胞活動の推定:刺激音によって誘発される蝸牛内の電気的活動の観察した.骨導超音波知覚に対しては蝸電図の一部の反応(CM, SP)が認められないことから,蝸牛の外有毛細胞の寄与が小さい可能性を明らかにした.
2. うなりの計測による蝸牛応答特性の推定:骨導超音波と周波数を変化させた気導音,骨導可聴音の間のうなりの発生の有無を検証した.骨導超音波と可聴音の間にうなりが全く観察されないことから,骨導超音波知覚における末梢メカニズムの特異性が示された.
3. 生体頭部を対象とした振動計測:被験者の頭部を対象とした振動計測を行い,頭部内で生じるマルチパス伝搬経路を推定する手法を提案した.今後実施予定の頭部内伝搬シミュレーションの高精度化に有用な知見を得た.

Current Status of Research Progress
Current Status of Research Progress

1: Research has progressed more than it was originally planned.

Reason

各サブテーマを当初計画通りに遂行できた.生理計測,心理計測の結果からは,骨導超音波知覚の特異な末梢メカニズムを示唆する興味深い結果を得た.また,複雑な頭部内伝搬経路を推定する手法を提案し,特許申請につなげるなど,計画以上の成果が出ていると言える.

Strategy for Future Research Activity

H27年度は各種電気生理計測(蝸電図計測,脳波計測,脳磁界計測),生理音響計測,心理計測,頭部や各組織に生じる振動モードの推定を進め,骨導超音波知覚のメカニズム推定に有用な知見の獲得に努める.H28年度は,それらの知見を統合して骨導超音波知覚モデルの構築を図り,その妥当性を検証することで,骨導超音波知覚のメカニズムの全貌を明らかにする.

Causes of Carryover

脳磁界計測用液体ヘリウムの購入,研究補助者の雇用費などを支出予定であったが,所属機関の内部交付金を充当することができた.

Expenditure Plan for Carryover Budget

H26年度未使用額を研究補助員雇用費に充当し,生理計測,心理評価を当初予定より大規模に実施することで,より高度な成果の獲得につなげる.
