Abstrakt: Cumulative auditory effects of repeated exposure to a 3-min 110 dB SPL white noise were examined in 20 subjects (10 male, 10 female). Statistical analysis revealed greater 8-kHz temporary threshold shift in female ears despite equivalent preexposure 8-kHz thresholds across gender. Cumulative effects were seen in thresholds of octave masking scores, especially in female subjects, possibly reflecting increased susceptibility following the second noise exposure.
