提出了一个简单的“语法”来描述“听觉子事件”，即开始、结束、填充和沉默如何在感知上联系起来。在特定频率范围内声音强度的快速增加作为开始的感知线索，而快速减小作为终止的线索。时频平面上一定时间内声能分布较厚表示有填充，而较厚部分后一定时间内声能分布较薄表示沉默。听觉系统似乎根据语法来解释这些线索，语法允许三种模式的“听觉事件”：（1）开始，然后是沉默，（2）开始和填充，然后是另一个开始，以及（3）开始，填充和结束，然后是沉默。更清晰的线索和背景有利于听觉事件的形成。当开始和终止被组织成“听觉流”时，接近原则就起作用了，...
A simple ‘‘grammar’’ is proposed to describe how ‘‘auditory subevents,’’ i.e., onsets, terminations, fillings, and silences, are connected perceptually. A rapid increase of sound intensity in a certain frequency range serves as a perceptual clue of an onset, whereas a rapid decrease serves as a clue of a termination. A thick distribution of sound energy for a certain duration in the time–frequency plane indicates a filling (or fillings), and a thin distribution of energy for a certain duration after a thicker part indicates a silence (or silences). The auditory system seems to interpret these clues according to the grammar, which allows three patterns of ‘‘auditory events’’: (1) an onset followed by a silence, (2) an onset and a filling followed by another onset, and (3) an onset, a filling, and a termination followed by a silence. Clearer clues and contexts facilitate the formation of auditory events. The proximity principle works when onsets and terminations are organized into an ‘‘auditory stream,’’ wh...
