Abstract(in English) The simultaneous equations method is one of active noise control algorithms without estimating an error path. This algorithm requires the identification of the transfer function from a reference microphone to error microphone, which includes the effect of a noise control filter, as the system identification of an auxiliary filter. As a result, an amount of computation is increased. In this paper, a new simultaneous equations method without the identification of an auxiliary filter. By storing an small number of an input signal and an error signal, we avoid this identification. Therefore, the amount of computation to about 3/4 is reduced and the same noise reduction performance with the ordinary method is obtained. From simulation examples, it is verified that the merits of the ordinary method is retained in the proposed method.
