Furthermore, change trends of gains from spatial release from masking with change of SNR are different in long enclosure and anechoic environment, and reflection effects at different locations of long enclosure have different effects on gains from spatial release from masking. 此外,长空间和无反射环境下空间去掩蔽带来的增益随信噪比变化的趋势不同,并且不同位置带来的不同反射对于长空间中的空间去掩蔽的增益有不同的影响。
