Abstract:Both Multi-channels filtered-X LMS and filtered-U LMS for active noise control are studied. The calculation formula of Multi-channels fihered-X LMS and filtered-U LMS is united by analyzing their algorithm, meanwhile the simulation is carried out. Then the multi-channel self-adaptive active noise control system is designed, and the noise control tests are processed in a close circumstance. Finally, the designed active noise control system is applied to bus, a good results of noise reduction is achieved.
Keywords:acoustics    multi-channel    filtered-X    filtered-U    active noise control
