| 摘 要： | 对频率在４ ０００ Ｈｚ 以下的纯音、方波和噪声在有时差或强度差时的主观感受进行的直接测试结果表明，通过双耳信号产生整体单一声源感，双耳信号需要有一个以上的频率成分．单频纯音并不能独自产生声源在不同位置的主观感受，且完全没有整体单一声源的感受．实验结果还表明所有频率成分的强度差、时差在半周期以下的频率成分的时差对声源的空间位置感起作用

| Abstract: | The hearing effects of interaural time and intensity differences of the noise, tones and rectwaves below 4000Hz were investigated directly by means of subjective evaluations.The experiment showed that more than one frequency components are needed to make an impression of a single integrated sound source, and that interaural intensity differences of all frequency components and interaural time differences of frequency components, whose the interaural time differences are shorter than the half cycle, contribute to location of sound image. |
