- 前記信号処理装置は,6個を超えるチャネルを含む,請求項6に記載の補聴器。
- 音響入力信号を電気信号に変換し,
少なくとも1個の周波数チャネルにおいて,上記電気信号の入力音圧レベルに応じた利得に基づいて上記電気信号を増幅する圧縮特性を有し,圧縮しきい値によって規定される出力音圧レベルが上記補聴器を使用する使用者の聴覚しきい値を下回る出力音圧レベルに設定されており,上記圧縮しきい値によって規定される入力音圧レベル以下の入力音圧レベルの上記電気信号を一定の利得に基づいて増幅し,かつ上記圧縮しきい値によって規定される入力音圧レベル以上の入力音圧レベルの上記電気信号を入力音圧レベルが高くなるにしたがって次第に利得を減少させて増幅し,かつ0.5秒を超えるアタックタイムを有する圧縮器を有する信号処理装置において,前記電気信号を処理し,
前記処理された電気信号を音響出力信号に変換する,
補聴器における音声信号の処理方法。 - 25dB未満の入力音圧レベルを超える前記信号を圧縮する,請求項8に記載の方法。
- 1秒を超えるアタックタイムの満了に基づいて前記信号を圧縮する,請求項8または9に記載の方法。
- 5秒を超えるリリースタイムの満了に基づいて前記信号の圧縮を停止する,請求項8,9または10に記載の方法。
- 前記信号を1.4を超える圧縮比で圧縮する,請求項8から11のいずれかに記載の方法。
- 帯域フィルタのそれぞれに接続されて,対応する帯域濾波派生信号を個別に圧縮する1組の圧縮器およびオフセット増幅器を有する信号処理装置において前記電気信号を処理する,請求項8から12のいずれかに記載の方法。
- 6個を超えるチャネルを有する信号処理装置において前記電気信号を処理する,請求項8から13のいずれかに記載の方法。
