Abstract (in Japanese) (See Japanese page) 
(in English) Active Noise Control(ANC) system reduces noise for using anti-noise. The ANC system using a virtual sensing method has been proposed for separating error microphone and zone of quiet. Most of the conventional virtual microphone methods adopts an open-loop structure. In contrast, we proposed a closed-loop virtual microphone method. In this paper, we expand single virtual microphone into multi- virtual microphone. The proposed method estimates the error signal on ZoQ by an auxiliary filter, and can control the noise on the virtual microphones.
