声音在混响环境中是局部化的，这一事实提出了一个尚未充分探讨的关键问题。下面将简要介绍我们所做的实验，这些实验证明存在优先效应，即一系列密集的声音中的第一个声音决定了声音被听到的地方。首次到达的重要性的证明清楚地表明了我们如何能够从普通硬墙房间的反射声音中排除模糊的线索。对优先效应的更广泛的测量已经通过合成四个点击的声音来进行，所述四个点击被安排为向代表一个位置的两个耳朵提供第一对，然后向代表不同位置的两个耳朵提供第二对。系统地研究了两个参数，第一对和第二对之间的间隔和第二对的时间视差。所有的测量都是通过改变第一对的视差来进行的，直到...
The fact that sounds are localized in reverberant surroundings points up a critical problem which has not been explored sufficiently. A brief description will be given of experiments we have done which demonstrate that there is a precedence effect, whereby the first in line of a series of closely spaced sounds is the one which determines the place where the sound is heard. This demonstration of the importance of first arrival makes clear how we are able to discount the ambiguous clues from the reflected sounds of an ordinary hard‐walled room. More extended measurements of the precedence effect have been made by synthesizing a sound out of four clicks arranged to give first one pair to the two ears representing one location, then a second pair to the ears representing a different location. Two parameters have been studied systematically, the interval between first pair and second pair, and the temporal disparity of the second pair. All measurements were made by varying the disparity of the first pair until...
