Abstract
【解決手段】 環境音を電気信号に変換するマイクロホン4と、このマイクロホン4の出力信号を補聴処理する補聴処理手段21と、この補聴処理手段21の出力信号を音響信号に変換するイヤホン6を備えた補聴器において、外耳道内の音を電気信号に変換する外耳道用マイクロホン7と、この外耳道用マイクロホン7の出力信号と補聴処理手段21の出力信号を比較し、外耳道用マイクロホン7の出力信号が補聴処理手段21の出力信号に近づくよう補聴処理手段21の出力信号を自動調整する適応フィルタ22を設けた。補聴処理手段21の出力信号を適応フィルタ22の入力信号xk及び希望信号dkとし、外耳道用マイクロホン7の出力信号を適応フィルタ22の応答信号ykとした。
【選択図】 図2
Description
この外耳道を密閉することによる不快感を取り除くために、従来から採られている手法は、外耳道を可能な限り開放させ(いわゆるオープンフィッティング)、この不快感を軽減させるものである(例えば、特許文献1〜3参照)。
補聴処理手段21は、マイクロホン4の出力信号に対してマルチバンドコンプレッションやノイズリダクション、トーンコントロール、ボリュームコントロール、出力制限装置など、補聴器装用者の聴力特性や使用環境に合わせた補聴処理を施し、装用者に適した補聴信号を出力する。
α = 1 - e-1/(fs・τ)の関係になる。fsはサンプリング周波数、τは時定数である。本発明の実施の形態では、fs =16,000Hz,τ=10ms にした。
