Title Changes over time in audiometric thresholds in a group of automobile stamping and assembly workers with a hearing conservation program
Bibliographic information July-Aug. 2002, Vol.63, No.4, p.482-487. Illus. 27 ref.
Abstract Noise-induced hearing loss afflicts millions of persons who work in noise above 85dBA. In this study of 301 workers at an automobile assembly plant, measurements were used to construct average lifetime noise exposure and hearing protection compliance estimates for use in modelling to predict total hearing loss and the onset of hearing loss. 16 subjects were found to have hearing loss at the speech frequencies (defined as an average hearing level ≥25dB at 500, 1000 and 2000Hz). In cross-sectional multivariate analyses, years of employment, male sex and proportion of time wearing hearing protection were the factors most associated with hearing loss at the average of 2000, 3000 and 4000Hz. The most consistent predictor of hearing loss in both univariate and multivariate analyses was percentage of time having used hearing protection during the workers' tenure.
