| Abstract(in English) | This study deals with an active noise reduction to improve an acoustical environment for the noisy room and factory. The proposed system is based on the noise detection system using a microphone array and an active noise control technique. The noise detection system is capable to get not only the original noise signal but its coming direction in the noisy sound field to be controlled. Therefore, it is is possible to effectively place an active noise source so as to make the controlled zone as wider as possible and also it is simpler to establish an adaptive noise reduction processing. Numerical simulation showed a reasonable performance in noise reduction, giving the maximum noise reduction level be 22dB and the effectively controlled area be nearly 0.96m^2. |
