Abstract

A new phenomenon is reported in which a change in spatial location of the leading sound source disrupts the normal echo suppression of the precedence effect. Click trains were presented through two loudspeakers, one leading the other by a few milliseconds. When leading and lagging signals were switched, listeners heard clicks momentarily for as long as several seconds from both loudspeakers before echo suppression was reestablished.

摘要

据报道，出现了一种新现象，即领先声源空间位置的变化会扰乱优先效应的正常回声抑制。通过两个扬声器呈现滴答声序列，其中一个扬声器比另一个提前几毫秒发声。当领先信号和滞后信号切换时，在回声抑制重新建立之前，听众会在几秒钟内同时从两个扬声器中短暂听到滴答声。
