A simple extension of the Webster-Jeffress model is presented together with its predictions for the effects of various stimulus parameters on the size of binaural masking-level differences (BMLDs). The four factors leading to BMLDs (just-noticeable differences (JNDs), temporal effects in simultaneous masking, binaural interaction, and temporal effects in non-simultaneous masking) are described, new measurements of the effect of signal duration on the detectability of interaural delay are presented, and the high degree of correlation between observers' sensitivity to changes in level and their sensitivity to changes in interaural delay is demonstrated. A number of examples illustrating where knowledge of JNDs for level and interaural delay and their joint dependence on certain stimulus parameters are sufficient to predict BMLDs are discussed.
本文提出了Webster-Jeffress模型的一个简单扩展，并给出了其对各种刺激参数对双耳掩蔽级差（BMLD）大小影响的预测。描述了导致BMLD的四个因素（刚可察觉差异（JND）、同时掩蔽中的时间效应、双耳相互作用以及非同时掩蔽中的时间效应），给出了信号持续时间对耳间延迟可检测性影响的新测量结果，并证明了观察者对电平变化的敏感度与他们对耳间延迟变化的敏感度之间的高度相关性。讨论了一些示例，说明电平JND和耳间延迟的知识及其对某些刺激参数的联合依赖性足以预测BMLD的情况。
