Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we proposed an active sinusoidal noise control system not requiring adaptive algorithm and secondary path filter. The estimation process of the normalized least mean square algorithm with step size one or less can be expressed as the step response of low pass filter. We show that the processing cost can be moreover reduced by substituting the arithmetic mean for the low pass filter. The following time can be thereby saved. Finally, we show that the proposed method successfully works by using computer simulations.
