To provide a noise control device etc., capable of effectively reducing noise.SOLUTION: The present invention relates to a noise control device 1 that reduces, at a seat 80 installed in a cabin in a noisy environment due to a predetermined noise source 200, noise nearby the head of a passenger sitting on the seat, and that comprises: a body weight sensor 60 installed at the seat; control speakers 31 and 32; a noise detector 10 detecting noise from the noise source and outputting a noise signal indicative of the detected noise; a control circuit 20 which acquires the noise signal and outputs a control signal for reducing the noise to the control speakers; and a memory 50 storing a plurality of control coefficients for generating the control signal for reducing noise at a position higher in a height direction from a seat surface as a body weight is heavier. The control circuit reads a control coefficient, corresponding to the body weight of a passenger detected by the body weight sensor or a correlation value, among the plurality of control coefficients, and outputs the control signal, generated using the noise signal and the read-out control coefficient, to the control speakers.SELECTED DRAWING: Figure 1

    【課題】効果的に騒音を低減することができる騒音制御装置などを提供する。【解決手段】所定の騒音源200により騒音環境下にある室内に設置された座席80において、座席に着座した乗員の頭部近傍の騒音を低減させる騒音制御装置1であって、座席に設置された体重センサ60と、制御スピーカ31、32と、騒音源からの騒音を検出し、検出した騒音を示す騒音信号を出力する騒音検出器10と、騒音信号を取得し、騒音を低減させる制御信号を制御スピーカへ出力する制御回路20と、体重が重いほど座面からの高さ方向において高くなる位置での騒音を低減させる制御信号を生成するための複数の制御係数を記憶しているメモリ50とを備え、制御回路は、メモリから、複数の制御係数のうち、体重センサにより検出された乗員の体重または相関値に対応する制御係数を読み出し、騒音信号と読み出した制御係数とを用いて生成した制御信号を制御スピーカへ出力する。【選択図】図1
