CHANGES IN THE HEARING OF PERSONNEL EXPOSED TO HIGH INTENSITY CONTINUOUS NOISE,
Abstract
The characteristics of the temporary and permanent threshold shifts of personnel acutely exposed to a high intensity noise, and to relate noise exposure to observed hearing loss were presented. The correlations obtained between noise exposure, as evaluated by the authors, and hearing loss, as determined by post-exposure audiometry, were not of statistical significance. The correlation between reference threshold and initial shift were negative and statistically significant, as was the correlation between reference threshold and permanent loss. The correlation betwen initial shift and permanent loss was positive and significant. Unreliability of reports by those exposed regarding details of exposure and individual differences in susceptibility to noise induced hearing loss might account for the lack of correlation between noise exposure and hearing loss.
