重要的是要知道感觉系统从自然刺激中提取了什么线索，以及大脑如何使用它们来形成感知。为了探索这个问题，Smith、Delgutte和Oxenham [Nature（伦敦）416，87-90（2002）]将一种声音的时间包络与另一种声音的精细时间结构混合以产生听觉嵌合体，并发现“包络的感知重要性随着频带的数量而增加，而精细结构的感知重要性则减少”。本研究探讨了嵌合化算法中自然耳蜗滤波和人工滤波振铃两个技术问题。此外，本研究发现，听觉嵌合体揭示的听觉知觉二分法是低频和高频处理之间的经典二分法的附带现象。最后，本研究发现，时间包络决定声音的位置，只要双耳水平差异线索存在。目前的结果加强了原来的假设，tempor…
It is important to know what cues the sensory system extracts from natural stimuli and how the brain uses them to form perception. To explore this issue, Smith, Delgutte, and Oxenham [Nature (London) 416, 87–90 (2002)] mixed one sound’s temporal envelope with another sound’s fine temporal structure to produce auditory chimaeras and found that “the perceptual importance of the envelope increases with the number of frequency bands, while that of the fine structure diminishes.” This study addressed two technical issues related to natural cochlear filtering and artificial filter ringing in the chimaerizing algorithm. In addition, this study found that the dichotomy in auditory perception revealed by auditory chimaeras is an epiphenomenon of the classic dichotomy between low- and high-frequency processing. Finally, this study found that the temporal envelope determines sound location as long as the interaural level difference cue is present. The present result reinforces the original hypothesis that the tempor...
