Active Noise Control of Reverberant Sound Field Using the Multi-Channel Adaptive Algorithm

다채널 적응 알고리즘을 이용한 잔향 음장에서의 능동소음제어에 관한 연구

In this study, Active noise controlis implemented with single channel and multi-channel adaptive algorithm in 3 dimensional reverberant enclosure sound. field, which occurrs in complicated acoustic mode. First, for the one case excited with the resonant frequency of an enclosure, a target of control and the other cases excited with band-pass filtered random noise(100~400Hz), it is implemented to control reducing interior noise of enclosure with single channel and realtime multi-channel adaptive algorithm for global noise reduction in enclosure.
