Threshold-duration functions for the acoustic reflex and threshold-duration functions based upon behavioral measures were obtained on the same group of subjects and compared. The mean temporal integration for the acoustic reflex threshold appears to be comparable to that for the behavioral threshold for stimuli of 500, 1000, and 2000 Hz, but marked individual differences exist in temporal integration of the acoustic reflex. At 4000 Hz, the mean change in the reflex threshold as a function of stimulus duration is significantly greater than the change in the behavioral threshold under the same conditions, suggesting that in the elicitation of the acoustic reflex the auditory system processes energy less efficiently at 4000 Hz than it does at lower frequencies.
针对同一组受试者，获取了声反射的阈值-时长函数以及基于行为测量的阈值-时长函数，并进行了比较。对于500、1000和2000赫兹的刺激，声反射阈值的平均时间整合似乎与行为阈值的平均时间整合相当，但在声反射的时间整合方面存在明显的个体差异。在4000赫兹时，反射阈值随刺激持续时间的平均变化显著大于相同条件下行为阈值的变化，这表明在引发声反射时，听觉系统在4000赫兹时处理能量的效率低于较低频率时的效率。
