Absolute thresholds at 4 and 6 kHz were tested in 3 sessions before and after 20 min exposure to 105 dB (A) pink noise in 12 young normal cycling females 11 young females under oral contraceptives and 8 young men. Women under oral contraceptives show lower resting thresholds, more important TTS2 and higher recovery rate than normal cycling women and men. In normal cycling females, non parametric analysis of the data provides evidence that absolute thresholds at 4 and 6 kHz tend significantly to be higher at menses and lower during the postovulatory phase of the cycle.
