Abstract(in Japanese) (See Japanese page)
Abstract(in English) Multi-channel feedforward ANC system can reduce various noise such as the broad-band noise by arranging the reference microphones close to noise sources. However, the performance of ANC system deteriorates when the reference microphones cannot be arranged close to noise sources because each microphone catches undesired noise in addition to desired noise. To solve this problem, we propose a multi-channel feedforward ANC system combined with sound source separation. This system uses microphone arrays as reference microphones and the separated signals is used as the reference signals of the ANC system. In this paper, we examine the effectiveness of the proposed system through some simulations.
