Abstract

A continuous 400-Hz tone (60-75 dB SPL) and 250-msec bursts of an 800-Hz tone (10 dB SL) were delivered dichotically. Four out of nine listeners were able to detect a 180 degree interaural phase shift. When a subaudible continuous 800-Hz tone was added to the ear with the 400-Hz tone, interaural phase-shift detection depended on the phase relation of the added tone to the 400-Hz tone. These results are shown to be consistent with the hypothesis of aural harmonic distortion.

摘要

以双耳分听的方式呈现一个持续的400赫兹纯音（声压级为60 - 75分贝）和一个800赫兹纯音的250毫秒脉冲串（阈上10分贝）。九名听众中有四名能够检测到180度的双耳间相位偏移。当在接收400赫兹纯音的耳朵中加入一个听阈下的持续800赫兹纯音时，双耳间相位偏移检测取决于所加纯音与400赫兹纯音的相位关系。这些结果表明与听觉谐波失真假说一致。
