The paper by Jesteadt and Norton [J. Acoust. Soc. Am. 78, 365-374 (1985)] described certain similarities between psychophysical and physiological measures of frequency selectivity. Although the hearing of naturally occurring sounds is dependent upon these peripherally based relationships, recent research has shown that other, more central, processes are also strongly involved in the perception of complex acoustic events. The present paper describes research on the discrimination of complex sounds other than those of speech or music. In contrast to the more peripherally determined limits on the listener's sensitivity for single tones and other simple stimuli, the processing of complex sounds requires the interaction of peripheral and central mechanisms. These issues are discussed in relation to recent studies of the responses of the cochlea to speech stimuli. It is suggested that the peripheral processor may be relatively transparent to the essential spectral-temporal properties of speech, whereas more central processing severely limits the rates and amount of information that can be extracted from complex sounds.
杰斯特德特和诺顿的论文[《美国声学学会杂志》78, 365 - 374 (1985)]描述了频率选择性的心理物理学测量与生理学测量之间的某些相似之处。虽然对自然声音的听觉依赖于这些基于外周的关系，但最近的研究表明，其他更中枢的过程也强烈参与了复杂声学事件的感知。本文描述了关于除语音或音乐之外的复杂声音辨别方面的研究。与单音和其他简单刺激的听众敏感度更多由外周决定的限制不同，复杂声音的处理需要外周和中枢机制的相互作用。结合最近关于耳蜗对语音刺激反应的研究来讨论这些问题。有人提出，外周处理器可能对语音的基本频谱 - 时间特性相对透明，而更中枢的处理严重限制了从复杂声音中可提取的信息速率和数量。
