Complex periodic auditory signals, produced by the Guttman-Julesz procedure of repeating segments of random noise, were employed to address the low region of auditory periodicity. Periodicity detection and discrimination tasks were examined with a common experimental procedure and a common measure of thresholds. Typically, detection and discrimination performance suffer at extremely low periodicities, presumably because of the extremely close spacing of harmonics throughout the auditory spectrum. Interaural phase effects are extremely weak for these signals, being largely confined to threshold-detection tasks. Despite qualitative phenomenological differences for different periodicity regions, detection and discrimination functions show no sharp discontinuities over a wide range of periodicities.
由古特曼-朱尔兹（Guttman-Julesz）重复随机噪声片段的程序产生的复杂周期性听觉信号，被用于研究听觉周期性的低频区域。使用一种常见的实验程序和一种常见的阈值测量方法来检验周期性检测和辨别任务。通常，在极低的周期性情况下，检测和辨别性能会变差，这可能是因为整个听觉频谱中谐波的间距极其紧密。对于这些信号，双耳相位效应极其微弱，主要局限于阈值检测任务。尽管不同周期性区域在定性现象学上存在差异，但检测和辨别功能在很宽的周期性范围内并没有明显的不连续性。
