本文根据前文提出的模型，解释了“第一波阵面定律”及其相关的双耳现象。SoC。上午好。80,1608-1622(1986)]，其中对侧抑制机制被添加到众所周知的双耳互相关模型中。为了验证扩展模型的预测，对通过耳机呈现的窄带脉冲对进行了心理声学实验。测试信号由一个主音和一个带有耳间到达时间差的“回声”组成。根据原声和回声之间的时间延迟测量偏侧化。对于回声阈值以下的延迟，模型模拟了求和局部化和第一波前规律；对于回声阈值以上的延迟，模型预测了原声对回波偏侧化的影响。
This paper explains the "law of the first wave front" and related binaural phenomena on the basis of the model presented in the previous paper [Lindemann, J. Acoust. Soc. Am. 80, 1608-1622 (1986)] in which a contralateral inhibition mechanism was added to the well-known model of binaural cross correlation. In order to verify the predictions of the extended model, psychoacoustic experiments were performed with pairs of narrow-band impulses which were presented through headphones. The test signals consisted of a diotic primary sound and an "echo" with an interaural arrival-time difference. Lateralization was measured as a function of the time delay between primary sound and echo. For delays below the echo threshold, summing localization and the law of the first wave front were simulated; for delays above the echo threshold, the model predicts an influence of the primary sound on the lateralization of the echo.
