Abstract
In this paper, we examine the effectiveness of Multi-channel feedforward active noise control (ANC) system combined with noise source separation through some simulations. 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. The proposed system separates noises by using microphone arrays as reference microphones and the separated signals are used as the reference signals of the ANC system. In simulation results, the proposed system can improve the noise reduction performance in case where the ANC system uses two reference microphones and the reference microphones do not need to be arranged close to the noise sources.
