Abstract
There is uncertainty how hearing loss accumulates over time from interrupted or intermittent exposures. This uncertainty has been compounded by the recent confirmation by Clark et al. of the original Miller et. al. observations on the improvement of pure-tone thresholds over time despite continued, regularly repeated (interupted) exposures. Clark et. al., using an octave band of noise centered at 0.5 kHz and presented at 95dB SPL on two different schedules (6 hours/day for 36 days or 15 minutes/hour for 144 days), showed that, although both exposures produced similar threshold shifts (TS) of 35 to 45 dB following the first day of exposure, the TS following exposure on subsequent days declined and, by 5 to 10 days of exposure, thresholds eventually came to within 10 to 15dB of pre-exposure values. Noise-induced permanent threshold shift (NIPTS) for these groups was less than that for the equal-energy non-interrupted noise exposure group.
