传统的无源吸振技术难以解决低频噪声控制问题 ,有源噪声控制(ANC)是解决低频噪声控制问题的有效方法。有源噪声控制 (ANC)通过引入可以控制的次级声源使其和主噪声源干涉相消而达到降噪的目的。介绍了常用的几种有源噪声控制 (ANC)算法 ,对常用ANC算法的性能进行了分析 ,并结合仿真结果对常用的ANC算法进行了评价。最后对算法的选择提出了建议 ,并对ANC的未来发展进行了展望。
The traditional passive vibration absorption technology is difficult to solve the problem of low-frequency noise control. Active noise control (ANC) is an effective method to solve the low-frequency noise control problem. Active noise control (ANC) achieves noise reduction by introducing a controllable secondary sound source to interfere with the primary noise source. Several commonly used Active Noise Control (ANC) algorithms are introduced, the performance of the commonly used ANC algorithm is analyzed, and the commonly used ANC algorithm is evaluated with the simulation results. Finally, the author puts forward some suggestions on the choice of algorithms and prospects the future development of ANC.
