摘要
Hearing acuity among electricians, plumbers and pipefitters, and boilermakers with greater than or equal to 20 years of union membership was compared with that of telephone workers. Automated pure tone audiometry was performed and a questionnaire was administered. Most construction workers were exposed to occupational noise and wore hearing-protection, Median thresholds for electricians and telephone workers were comparable. Thresholds of plumbers and pipefitters were higher but comparable to expected values. Boilermakers had high levels of hearing loss. Thresholds at 4000 Hz among older workers were similar for all groups and were above expected values, suggesting a cohort effect. Audiometric screening seems to be warranted for some construction workers.
