This study replicated Silman's [J. Acoust. Soc. Am. 66 (1979a)] experiment comparing acoustic reflex thresholds in normal hearing young and elderly subjects. The original study was modified so that the criterion for normal hearing was extended through 8000 Hz, and the range of auditory thresholds among the younger group was selected to approximate those of the elderly subjects as closely as possible. The data confirmed those reported by Silman, showing an elevation of the ART for broadband noise, but nor for tonal activators in the elderly group.
本研究重复了西尔曼[《美国声学学会杂志》66 (1979a)]的实验，比较了听力正常的年轻人和老年人的声反射阈值。对原研究进行了修改，以便将正常听力的标准扩展到8000赫兹，并且尽可能紧密地选择较年轻组的听觉阈值范围以接近老年受试者的阈值范围。数据证实了西尔曼报告的结果，表明老年组中宽带噪声的声反射阈值升高，但音调刺激源的声反射阈值没有升高。
