基于单通道音频信号分离的声反馈控制

摘要

Due to the problem of lack of reliability in the available methods, a new solution is constructed for acoustic feedback control using single channel blind source separation. The main advantage of this solution is that the result has nothing to do with the feedback path so that it has high reliability. Computer simulations are given to demonstrate the performance of this method.%针对现有多种声反馈控制算法对环境变化敏感的问题，将单通道音频信号分离法用于声反馈控制中。仿真结果表明，所述方法在助听器和公共扩音系统中的声反馈控制效果突出，环境的改变对声反馈抑制的效果没有明显的影响，鲁棒性强。
