摘要
提出了一种通过频域内的加权手段,将心理声学模型的掩蔽效应特性应用到有源噪声控制系统中的有源噪声控制方法。详细给出了将掩蔽效应特性具体应用到有源噪声控制中的实现方法。仿真结果证明了这种新的有源噪声控制方法降低了噪声的分贝量,改善了频谱特性,提高了残余噪声的主观性能。
A new control method of ANC is proposed in this paper.Namely,it applies the masking effect of the psychological acoustics model to ANC by assigning different weights to the different frequency components of the noise,which is realized with the BP artificial intelligent network.Simulation results show that the method can not only reduce the noise level in decibels,but also amend the spectrum feature and improve the subjective perfor-mance of residual noise.[
