大量的调查研究了听觉系统在侧化任务中以时间换取强度的能力。然而，大多数这些调查，采用点击和噪声爆发的刺激与发病时间之间的耳间差异。因此，缺乏定量数据的时间强度贸易纯音，具有相同的起始时间，但不同的相位作为信号。由于这个原因，我们采用了范围从200到2000 Hz的正弦波，并且确定了当以30度增量在双耳信号之间施加0度到360度的耳间相位差异时，一个信号的强度必须降低到何种程度以实现中线图像。实验中得到的时间-强度交换函数表明：（1）最大的时间-强度交换是在较低频率下完成的，这并不意外;（2）每个频率的最大时间-强度交换发生在耳间相位差为90度和270度时;以及（3）当低频音调为180度异相时，基本上需要与0度耳间相位条件所需的相同的耳内强度关系来实现中线。
A substantial number of investigations have examined the ability of the auditory system to trade time for intensity on a lateralization task. Most of these investigations, however, have employed clicks and noise bursts as stimuli with interaural disparities between onset times. Consequently, there is a lack of quantitative data for time-intensity trades where pure tones that had identical onset times but disparate phase were employed as signals. For this reason we employed sinusoids ranging from 200 to 2000 Hz and determined the extent to which the intensity of one signal must be decreased to achieve a midline image when interaural phase disparities of 0 degrees to 360 degrees were imposed between the binaural signals in 30 degree increments. The time-intensity trading functions yielded in this experiment demonstrate that (1) not unexpectedly, the largest time-intensity trades were accomplished for the lower frequencies; (2) the maximum time-intensity trade for each frequency occurred at interaural phase disparities of 90 degrees and 270 degrees; and (3) when the low-frequency tones were 180 degrees out of phase, essentially the same intraaural intensity relationship was required to achieve midline as was needed for the 0 degree interaural phase condition.
