摘　　要：对被污染的语音信号的去噪进行了讨论与分析,应用异于DJ硬、软门限的新门限法对语音信号进行了去噪的仿真计算,结果确实优于DJ软。A new method for speech denoising is presented which uses a new threshold different from DJ's thresholds.Preliminary computer simulations were performed on speech signals and resulted in better performance than that by using DJ's thresholds.
