Humans are able to detect an instantaneous change in correlation, demonstrating an ability to temporally process extremely rapid changes in interaural configurations. This temporal dynamic is correlated with human listeners' ability to store acoustic features in a transient auditory manner. The present study investigated whether the ability of transient auditory storage of acoustic features was affected by the interaural delay, which was assessed by measuring the sensitivity for detecting the instantaneous change in correlation for both wideband and narrowband correlated noise with various interaural delays. Furthermore, whether an instantaneous change in correlation between correlated interaural narrowband or wideband noise was detectable when introducing the longest interaural delay was investigated. Then, an auditory computational description model was applied to explore the relationship between wideband and narrowband simulation noise with various center frequencies in the auditory processes of lower-level transient memory of acoustic features. The computing results indicate that low-frequency information dominated perception and was more distinguishable in length than the high-frequency components, and the longest interaural delay for narrowband noise signals was highly correlated with that for wideband noise signals in the dynamic process of auditory perception.
人类能够检测到相关系数的瞬时变化，这表明人类具有处理耳间配置极其快速变化的时间处理能力。这种时间动态与人类听众以瞬态方式存储声音特征的能力相关。本研究通过测量检测宽带和窄带相关噪声的相关系数瞬时变化的敏感性，评估了耳间延迟对瞬态听觉存储声音特征能力的影响。此外，当引入最长的耳间延迟时，研究了相关的窄带或宽带噪声之间的相关系数的瞬时变化是否可检测。然后，应用听觉计算描述模型来探索在各种中心频率下的宽带和窄带模拟噪声与听觉过程中下一级瞬态记忆的声音特征之间的关系。计算结果表明，低频信息主导感知，在长度上比高频成分更具可分辨性，而窄带噪声信号的最长耳间延迟与宽带噪声信号在听觉感知的动态过程中高度相关。
