This study investigated whether sound intensity affects listeners' sensitivity to a break in interaural correlation (BIC) embedded in wideband noise at different interaural delays. The results show that the detection duration threshold remained stable at the intensity between 60 and 70 dB SPL, but increased in accelerating fashion as the intensity decreased toward 40 dB SPL. Moreover, the threshold elevated linearly as the interaural delay increased from 0 to 4 ms, and the elevation slope became larger as the intensity decreased from 50 to 40 dB SPL. Thus, detecting the BIC is co-modulated by both intensity and interaural delay.
本研究旨在探讨声强是否会影响听者对宽带噪声中双耳相关中断（BIC）的敏感度，且该中断分别位于不同的两耳延迟处。结果表明，在 60 至 70 dB SPL 的声强范围内，检测持续时间阈值保持稳定，但随着声强向 40 dB SPL 降低，阈值呈加速上升趋势。此外，随着两耳延迟从 0 增加到 4 ms，阈值呈线性增加，且随着声强从 50 降低到 40 dB SPL，斜率增大。因此，BIC 的检测受到强度和两耳延迟的共同调制。
