Description
ここで、バンド幅が広がった難聴者の聴覚フィルタの感度を純音の最小可聴閾値特性であるオージオグラム(図2)に合わせて考えると、難聴者の聴覚フィルタバンクは、図3に示すように表される。
先ず、ステップSP1において、被験者のオージオグラム3を測定する。次いで、ステップSP2において、複数の中心周波数における聴覚フィルタからなる聴覚フィルタバンク2を測定する。
Claims (3)
- 聴覚フィルタバンクを構成する聴覚フィルタの各周波数における感度を決定する装置であって、レベルと周波数特性が既知である測定信号を発生する測定信号出力手段と、予め測定された被験者の聴覚フィルタバンクと、予め測定された被験者の前記測定信号の最小可聴閾値特性を備えると共に、前記聴覚フィルタバンクに前記測定信号を入力した際に出力される信号の総エネルギーと前記最小可聴閾値特性より、聴覚フィルタの感度を決定する演算処理手段を設けたことを特徴とする聴覚フィルタ感度の決定装置。
- 聴覚フィルタバンクを構成する聴覚フィルタの各周波数における感度を決定する装置であって、レベルと周波数特性が既知である測定信号を発生する測定信号出力手段と、予め測定された被験者の聴覚フィルタバンクと予め測定された被験者の前記測定信号の最小可聴閾値特性から、前記聴覚フィルタバンクを構成する聴覚フィルタの各周波数における感度を決定し、この決定された感度に基づいて、測定されていない中心周波数における聴覚フィルタの感度及び/又は最小可聴閾値を推定する演算処理手段を設けたことを特徴とする聴覚フィルタ感度の決定装置。
- 聴覚フィルタバンクを構成する聴覚フィルタの各周波数における感度を決定する装置であって、レベルと周波数特性が既知である測定信号を発生する測定信号出力手段と、予め測定された被験者の聴覚フィルタバンクと予め測定された被験者の前記測定信号の最小可聴閾値特性から、測定されていない中心周波数における聴覚フィルタ及び/又は最小可聴閾値を推定し、これらの推定値に基づいて聴覚フィルタの感度を決定する演算処理手段を設けたことを特徴とする聴覚フィルタ感度の決定装置。
