基于次级声源布局优化的主动降噪实验研究
Experimental Research on Active Noise Reduction Based on Secondary Sound Source Layout Optimization
摘要
Abstract
This paper proposed an optimization method of secondary sound source layout based on the Monte Carlo method of acoustic simulation.A multi-channel active noise control (ANC) algorithm was firstly deduced;And then a dual-channel ANC experiment system was established;Finally, the influence of secondary sound source layout optimization on ANC system performance was studied by conducting a simulation and noise reduction experiment.The experimental results show that, for single frequency and mixed noise, an ANC system with secondary sound source optimization layout has a better noise reduction efficiency and a wider noise reduction area than the one without it.With little restriction, the optimization method can be used in most kinds of ANC system.关键词
