Masking-level differences (MLDs) were measured for trains of 2000-Hz bandpass clicks as a function of the interclick interval (ICI) and the number of clicks in the train. The magnitude of the MLD grew as the number of clicks in the train was increased from 1 to 32. While the MLDs tended to be larger at longer ICIs, the effect was mediated by changes in detectability in the homophasic conditions. For click trains consisting of 4-32 clicks, the improvement in detectability in the antiphasic conditions with increases in the number of clicks appears to be the result of integration of acoustic power, as is the case for the homophasic conditions. The absence of MLDs for short trains of high-frequency transients remains quite puzzling, since large MLDs are found with single, low-frequency transients.
测量了2000赫兹带通咔嗒声序列的掩蔽级差（MLD），作为点击间隔（ICI）和序列中咔嗒声数量的函数。随着序列中咔嗒声数量从1增加到32，MLD的幅度增大。虽然在较长的ICI时MLD往往更大，但这种效应是由同相条件下可检测性的变化介导的。对于由4 - 32次咔嗒声组成的咔嗒声序列，反相条件下随着咔嗒声数量增加可检测性的提高似乎是声功率整合的结果，同相条件下也是如此。高频瞬态短序列不存在MLD仍然相当令人费解，因为单个低频瞬态会出现较大的MLD。
