Abstract (in Japanese) (See Japanese page) 
(in English) In the active noise control, the simultaneous equations method that doesn't need the secondary path filter has already been proposed.
The simultaneous equations method solves an equation after a Additional filter to solve the simultaneous equations converges, and calculates the filter coefficient of the desire.
Therefore, it is important to know the convergence time of a Additional filter. Moreover, the adaptive algorithm is hoped not to be influenced easily from the correlation of the reference signal, and to converge with stability in the active noise control because the sound in general is colored and nonstationary in general.

To solve these problems, we has already been proposed the adaptive algorithm updating coefficient in the frequency domain, and reported the steady operation in the whited reference signal.

This paper presents the convergence property by the simulation when this frequency domain adaptive algorithm is applied to a colored reference signal and a real noise.
