 note = {本稿では，フィードバック型に Normalized Least Mean Square (NLMS) 法と Sub Recursive Least Square (Sub-RLS) 法を，フィードフォワード型に Filtered-x LMS と周波数変換法を適用して得られる低減効果を比較する．その比較に際して，到来正弦波には１秒間に 5 Hz，50 Hz，100 Hz，500 Hz の周波数変化を与える．また，実用時において避けられない周囲騒音の影響についても比較する．最後に，周波数変換法に優位性があることを示す．, In this paper, we compare the noise reduction effects provided by the feedback type applying the normalized least mean square (NLMS) algorithm and sub recursive least square (sub-RLS) algorithm and feedfoward type applying the filtered-x least mean square (LMS) algorithm and the frequency conversion method to active sinusoidal noise control, on condition that the frequency change of 5, 50, 100 and 500 Hz per one second is applied to the target noise consisting of sine waves of 200, 300, 400, 500 and 600 Hz. We moreover compare the degeree reduced by surrounding noise superimposing on the target niose and finally show that the frequency conversion method is superior into the others.},
