在使用具有逐渐变化的耳间时间延迟 (.DELTA.Ts) 的喀哒声刺激的双耳刺激后，对受试者进行长潜伏期听觉诱发电位 (AEP) 测试。通过适当改变ΔT，该声音信号可以产生移动的融合听觉图像（FI）的感觉。结果发现，随着点击率增加到 15 Hz 以上，AEP 的 N1-P2 复合体振幅上升，并且移动 FI 的幅度比未移动 FI 的幅度更大。对于未移动的 FI，双耳掩蔽释放（通过 AEP 的双耳掩蔽电平差 (BMLD) 测量）总计为 6 dB。对于移动 FI，左半球和右半球的 AEP BMLD 分别为男性 2.8 和 3.5 dB，女性 13.4 和 11.3 dB。在受到“移动”和“不动”声音刺激后，女性 N1-P2 复合波的振幅大于男性。
Long-latency auditory evoked potentials (AEPs) were tested in subjects following binaural stimulation with click trains with gradually changing interaural time delays (.DELTA.Ts). With appropriate change of the .DELTA.Ts this sound signal could produce the sensation of a moving fused auditory image (FI). It was found that the N1-P2 complex of the AEPs rose on amplitude with the increase of the click rate above 15 Hz, and to a greater extent for the moving than for the unmoved FIs. Binaural release from masking (as measured by the binaural masking level difference (BMLD) for the AEPs) amounted to 6 dB for the unmoved FI. For the moving FI the BMLD for the AEPs amounted to 2.8 and 3.5 dB in men and 13.4 and 11.3 dB in women, for the left and right hemispheres respectively. The amplitude of N1-P2 complex following stimulation with the ''moving'' and ''unmoved'' sounds was larger in women than in men.
