摘要
主动噪声控制研究虽然比较多,但大多数集中在频率成分比较单一的设备上。由于发动机噪声的频率成分比较复杂,如果采用主动降噪技术不能适时采集到源噪声信号,就达不到理想的降噪效果。文章尝试采用由无限脉冲滤波器组成的多通道控制策略,从理论上解决源噪声信号采集问题,其实质效果还有待于后续实验验证。
The research of Active Noise Control is comprehensive,but in most cases it is used on single frequency equipment.Because engine noise takes on complicated frequency characteristics,if original noise signal is not collected,the noise control effect will not be evident.In this paper a multi-passage controlling tactic composed of infinity impulse filter is presented to solve the problem in theory,but actual effect must be verified by experiment in future.
