Contralateral acoustic reflex thresholds (ARTs) were determined daily in 10 normal women and 10 men, aged 18-24, in response to a broad-band noise, over a 32-day period. Mean ARTs for men vs women over the period differed by only 1.55 db, but for women a stimulus level of about 6 db more was required to elicit ART over Days 1-6 of the menstrual cycle than over Days 7-26 (p less than .01). There was furthermore an increase in sensitivity in the luteal phase (Days 15-19) of the cycle. It appears that the changes in ART throughout the cycle mirror, and may reflect, concomitant changes in the hormonal (estrogen and progesterone) levels. Changes in ART over the cycle may thus be explained by hypothesizing that the ART is an aspect of sensorineural behavior affected by hormonal concentrations to which a number of other auditory phenomena are known or thought to be related.
在32天的时间里，每天对10名年龄在18至24岁之间的正常女性和10名正常男性进行对侧听觉反射阈值（ARTs）测定，以回应宽带噪声。在此期间，男性与女性的平均ARTs仅相差1.55分贝，但女性在月经周期的第1至6天比第7至26天需要约6分贝更高的刺激水平才能引发听觉反射阈值（p小于0.01）。此外，在月经周期的黄体期（第15至19天）敏感性有所增加。整个周期中听觉反射阈值的变化似乎反映了，并且可能体现了，激素（雌激素和孕激素）水平的相应变化。因此，周期中听觉反射阈值的变化可以通过假设来解释，即听觉反射阈值是感觉神经行为的一个方面，受激素浓度影响，而许多其他听觉现象已知或被认为与之相关。
