Abstract

Binaural masking-level differences (BMLDs) were measured for tones at frequencies below and above masking noises centred on 250 Hz, having 10, 31.6 or 100 Hz bandwidths and either 40 or 60 dB spectral density levels. The BMLD drops rapidly when masker and signal have no frequency components in common. The magnitude of the decrease in the BMLD is not merely a result of the reduced masking effect and is not to be predicted by the models of Durlach [2] or Schenkel [12].

摘要

测量了以250Hz为中心、带宽为10Hz、31.6Hz或100Hz且频谱密度水平为40dB或60dB的掩蔽噪声上下频率的纯音的双耳掩蔽级差（BMLD）。当掩蔽声和信号没有共同的频率成分时，BMLD会迅速下降。BMLD下降的幅度不仅仅是掩蔽效应降低的结果，并且不能由Durlach [2]或Schenkel [12]的模型预测。
