Abstract

　騒音を抑圧する制御音をスピーカ（６）より生成するための制御信号（ｙ*）として最適な候補を、複数の制御信号候補（ｙ1～ｙn）の中から、選択機能部（１１）により選択する。この選択のために、エラーマイク（７）からの残留騒音信号（ｅ）を入力とする残留騒音推定機能部（１２）を導入する。該機能部（１２）はまず、騒音成分の推定値を第１伝達特性模擬フィルタ（２１）を用いて得る。さらにこの騒音成分推定値と、第２伝達特性模擬フィルタ（２２－１～２２－Ｍ）からの各濾波出力とを用いて、各上記制御信号候補（ｙ1～ｙn）についての残留騒音推定値を得る。そしてこれら残留騒音推定値のうち最小のものに対応する１つの上記制御信号候補を選択し、これを上記制御信号（ｙ*）とする。
