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.
本文基于前一篇论文[林德曼，《美国声学学会杂志》80, 1608 - 1622 (1986)]中提出的模型，解释了“第一波前定律”及相关双耳现象。在前述模型中，在著名的双耳互相关模型基础上添加了对侧抑制机制。为验证扩展模型的预测，使用通过耳机呈现的成对窄带脉冲进行了心理声学实验。测试信号由双耳同相的初级声音和具有耳间到达时间差的“回声”组成。侧向定位作为初级声音与回声之间时间延迟的函数进行测量。对于低于回声阈值的延迟，模拟了总和定位及第一波前定律；对于高于回声阈值的延迟，该模型预测初级声音对回声侧向定位有影响。
