Listeners were asked to detect interaural differences of intensity in trains of 4000-Hz clicks as the interclick interval (ICI) was varied from 10 to 1 ms and the number of clicks in a train (n) was varied from 1 to 32. As has previously been shown for differences of time [Hafter and Dye, J. Acoust. Soc. Am. 73, 644-651 (1983)], plots of log interaural threshold versus log n produced slopes that decrease with ICI. These results are explained in terms of a saturation model which argues that as the click rate increases, the evoked neural activity changes from what is essentially a tonic response toward one that is more phasic.
当4000赫兹的滴答声序列中的滴答间隔（ICI）从10毫秒变化到1毫秒，且序列中的滴答数（n）从1变化到32时，要求听众检测强度的双耳差异。正如之前针对时间差异所表明的那样[哈fter和戴伊，《美国声学学会杂志》73, 644 - 651 (1983)]，对数双耳阈值与对数n的关系图所产生的斜率会随着ICI的减小而减小。这些结果是根据一个饱和模型来解释的，该模型认为随着滴答速率的增加，诱发的神经活动从本质上的紧张性反应转变为更具相位性的反应。
