这项研究旨在调查人类听者是否能够在频率恒定(频率稳定)或频率变化(单向频率滑动)的噪声中检测到嵌入在双耳相同的任意噪声标记[相关性中断，耳间相关性中断(BIAC)]中的双耳不相关的任意噪声片段。在实验一中，对10名听力正常的受试者进行了上滑、下滑和稳频噪声的测试。在实验2a中，对21名听力正常的受试者进行了上滑音和稳频音的测试。在实验2b中，另外19名听力正常的参与者被测试了下行和频率稳定的噪音。听者能够在频率稳定的噪声(中心频率=400赫兹)和两种类型的频率滑动噪声(中心频率：100至1,600赫兹)中检测到BIAC。在频率滑动噪声中检测BIAC的持续时间阈值显著长于频率稳定噪声(实验1)，而在频率滑动噪声中检测到持续时间固定的BIAC(200ms)的最长耳间延迟显著短于频率稳定噪声(实验2)。虽然人类听众可以在频率滑动噪声中检测到BIAC，但他们在频率滑动噪声中对BIAC的敏感度远远低于频率稳定噪声中的BIAC。
This study was to investigate whether human listeners are able to detect a binaurally uncorrelated arbitrary-noise fragment embedded in binaurally identical arbitrary-noise markers [a break in correlation, break in interaural correlation (BIAC)] in either frequency-constant (frequency-steady) or frequency-varied (unidirectionally frequency gliding) noise. Ten participants with normal hearing were tested in Experiment 1 for up-gliding, down-gliding, and frequency-steady noises. Twenty-one participants with normal hearing were tested in Experiment 2a for both up-gliding and frequency-steady noises. Another nineteen participants with normal hearing were tested in Experiment 2b for both down-gliding and frequency-steady noises. Listeners were able to detect a BIAC in the frequency-steady noise (center frequency = 400 Hz) and two types of frequency-gliding noises (center frequency: between 100 and 1,600 Hz). The duration threshold for detecting the BIAC in frequency-gliding noises was significantly longer than that in the frequency-steady noise (Experiment 1), and the longest interaural delay at which a duration-fixed BIAC (200 ms) in frequency-gliding noises could be detected was significantly shorter than that in the frequency-steady noise (Experiment 2). Although human listeners can detect a BIAC in frequency-gliding noises, their sensitivity to a BIAC in frequency-gliding noises is much lower than that in frequency-steady noise.
