auditory masking threshold 听觉遮蔽临界
Then,a masking threshold is used to continually adjust the MMSE estimate gain function which adjusts the noise reduction. This approach significantly reduces attenuation of weak speech signals to reduce spectral distortion of the enhanced speech.
该算法在最小均方误差准则下引入语音存在的概率,得到软判决修正的增益函数,然后利用掩蔽门限不断地调整增益函数,进而调整噪声的抑制程度,保护微弱的语音信号,减少语音谱的失真。
