Abstract
The effectiveness of a Hearing Conservation Program was evaluated at six chemical manufacturing facilities. All regular, full time white male employees having a 1985 hearing test were included in this analysis of hearing loss and impairment. Hearing loss was calculated separately for the speech range and the high tones. Of the 1909 employees tested in 1985, 87% met the criteria for the study of hearing loss and impairment, and 48% qualified for the longitudinal analysis. A substantially larger percentage of the population experienced hearing loss in the high frequency ranges than in the speech range. Both speech range and high frequency hearing loss appeared greater in older employees, employees in the maintenance job category, and employees of one of the six facilities. The relationship between employment facility and hearing loss was statistically significant. In the longitudinal analysis, the most notable finding was that instead of observing a gradual deterioration of hearing, an apparent improvement in hearing acuity was consistently present in nearly all segments of the study population.
