Abstract

　本発明の能動消音装置は、騒音と干渉する制御音を発生するスピーカと、前記干渉後に残る騒音を残留騒音信号として検出するマイクと、前記残留騒音の音質を評価して音質評価結果を出力する音質評価部と、前記音質評価結果に応じて、前記騒音に対応する参照信号の複数の帯域に対応する、前記残留騒音の複数の帯域に対して、どのタイミングで検出した残留騒音信号の周波数成分を前記制御音を生成するときに使用するかを決定する動作信号決定部と、決定された残留騒音信号の複数の帯域と、前記騒音に対応する参照信号の複数の帯域とに基づいて、前記制御音を生成するための制御信号を生成して出力する制御信号生成部と、を備える。
