摘　　要：为了对复杂声环境下的噪声进行有效控制,同时不影响人们对有用声信号的理解,提出一种基于多声源环境的有源噪声控制算法。该算法将单独的非控制目标声信号引入控制系统中,以抵消误差信号中与其相关部分,从而使控制器生成的次级信号仅与噪声相关。实验结果表明,使用该算法的降噪系统对噪声进行控制时,不会影响人们对有用声信号的理解。In order to control the noise effectively in complicate sound environments without affecting people’s understanding of useful sound signals,an active noise control algorithm based on multi source environment is proposed.In this algorithm,the separate nontarget sound signal is introduced into the control system in order to cancel the relevant part of error signal,so that the secondary signal generated by the controller is only related to the noise.The experimental results show that when the noise is controlled by the noise reduction system using this algorithm,people’s understanding of the useful acoustic signal in such an environment will not be affected.
