本研究探讨当信号在左右耳间相移180度时，双耳掩蔽水平差异在嵌入噪声中的语音的检测和识别中的作用。对10名听力正常的受试者进行了噪声掩蔽下的瑞典语spondaic词的双耳测试。结果提出的语音检测阈值，语音识别阈值，语音识别与信噪比的心理测量功能，和语音清晰度作为双耳清晰度水平差的函数。当语音信号相移180度时，语音检测阈值和语音可懂度都得到改善。双耳可懂度水平差异范围为5.7至7.7 dB。
This study investigates the binaural masking level difference in both detection and recognition of speech embedded in noise when the signal is phase-shifted 180 degrees between the left and the right ear. Swedish spondaic words masked by noise werc presented binaurally to 10 normally hearing subjects. The results are presented in terms of speech detection threshold, speech recognition threshold, a psychometric function of speech recognition versus signal-to-noise ratio, and speech intelligibility as a function of binaural intelligibility level difference. Both speech detection threshold and speech intelligibility improved when the speech signal was phase-shifted 180 degrees. The binaural intelligibility level difference ranged from 5.7 to 7.7 dB.
