19232 声信号在空间中的传播具有较强的多径效应，在接收端往往以卷积形式相互叠加，尤其在海洋、剧场等强混响条件下，混合滤波器冲激响应的长度会显著增加，现有的频域卷积盲分离算法将失效。 The propagation of acoustic signal in space has a strong multipath effect, and the receiver often overlaps in the form of convolution. Especially in strong reverberation conditions such as ocean and theatre,where the length of impulse response of hybrid filter increases significantly.
