Abstract (in Japanese) (See Japanese page) 
(in English) 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.
