The aim of this research was to investigate the influences of the menstrual cycles of women on temporary threshold shift (TTS) and to compare the results with TTS of men. The subjects were, after 5 min rest, exposed to 100dB of continuous white noise for 8 min. The audiometry with a 4000 Hz test tone was done in the 45-min recovery process. In the three phases of the menstrual cycle, TTS tended to be lower in postovulatory phase than in preovulatory phase and during menstruation. The male TTS was higher than that of the female in all phases of menstrual cycle.
本研究的目的是调查女性月经周期对暂时性阈移（TTS）的影响，并将结果与男性的TTS进行比较。受试者在休息5分钟后，暴露于100分贝的连续白噪声中8分钟。在45分钟的恢复过程中，使用4000赫兹测试音进行听力测定。在月经周期的三个阶段中，排卵后期的TTS往往低于排卵前期和月经期。在月经周期的所有阶段，男性的TTS均高于女性。
