【摘要】 提出了基于神经网络模型的耳机噪声消除系统的设计方法。采用自适应逆控制的思想,基于ε-滤波LMS算法构造神经网络控制器,其输出驱动耳机内扬声器,以自适应消除进入耳机内的强外界环境噪声。仿真结果表明,本文方法比基于线性模型具有更好的消噪性能。更多还原

【Abstract】 New design method of canceling earphone noise based on neural network is presented. A neural network controller is given by the filtered-εLMS algorithm in terms of adaptive inverse control. The output of loudhailer driven by the controller clears up the outside noise in earphone. Simulation results show that the proposed method has better performance of canceling earphone noise than that of using the linear model.更多还原
