Because of considering the temporal masking effects to set up a threshold and the valid hop size of transient points, this method is very suitable for perceptual audio coding.
由于考虑了时域掩蔽效应来设置检测门限和有效瞬态点间隔，非常适用于感觉音频编码。
And in perceptual weighting stage, auditory masking effect is used. A perceptual weighting filter is designed to filter the enhanced speech by spectral subtraction so as to remove residual noise.
在感知加权处理中充分利用了人耳的掩蔽效应，设计了感知加权滤波器，对谱减法增强后的语音进行滤波，进一步消除残余噪声。
