摘要: In this paper, we verify the performance of multiple-channel active noise control systems using simultaneous equations method. This method has advantage that it can automatically recover reduction effect degraded by acoustic path changes. The is hence applied to single-channel systems, and also shown results in better performances than filtered-x algorithm. extend extended impulse responses measured with an experimental system. a 1-2-2 system, consisting one detection microphone, two loudspeakers error microphones, 2-2-2 system including resulting reductions 14 18 dB, respectively. result demonstrates well works for systems.
