当掩蔽声和信号没有共同的频率分量时，双耳掩蔽模式显示双耳掩蔽水平差（BMLD）急剧下降。实验阈值数据与模型模拟一起提出了一个diotic掩蔽中心在250或500 Hz和10或100 Hz的带宽掩蔽一个正弦曲线interaurally在相位（S（0））或反相（S（π））。双耳模型的仿真，包括一个调制滤波器组的单声道分析，表明在远程掩蔽条件下的BMLD的减少的很大一部分可能是由于一个额外的调制提示可用于单声道检测。
Binaural masking patterns show a steep decrease in the binaural masking-level difference (BMLD) when masker and signal have no frequency component in common. Experimental threshold data are presented together with model simulations for a diotic masker centered at 250 or 500 Hz and a bandwidth of 10 or 100 Hz masking a sinusoid interaurally in phase (S(0)) or in antiphase (S(π)). Simulations with a binaural model, including a modulation filterbank for the monaural analysis, indicate that a large portion of the decrease in the BMLD in remote-masking conditions may be due to an additional modulation cue available for monaural detection.
