Temporary Threshold Shift for "Normal" Subjects As a Function of Age and Sex

Abstract

Research was performed to determine whether there are variations in temporary threshold shift (TTS) for normal individuals exposed to intense (110 dB), broad band (1200-2400 cps) noise as a function of age and sex. At 2,000 cps there was considerably less TTS for males than for females. At 4,000 cps no such differences were observed. The smallest difference in TTS for men and women was observed for subjects under 30. The significant differences may have indicated that susceptible males more frequently sustain a permanent loss and so would be in eligible as subjects for this kind of experiment. There is no support from these data for the hypothesis that males are biologically more susceptible to hearing loss than females.
