Hearing acuity among electricians, plumbers and pipefitters, and boilermakers with > or = 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.
将电工、水管工和管道工以及拥有20年及以上工会会员资格的锅炉工的听力敏锐度与电话工人的进行了比较。进行了自动纯音听力测定并发放了问卷。大多数建筑工人都接触过职业噪声并佩戴听力保护装置。电工和电话工人的中位数阈值相当。水管工和管道工的阈值较高，但与预期值相当。锅炉工有较高程度的听力损失。所有组中年龄较大工人在4000赫兹时的阈值相似且高于预期值，这表明存在队列效应。对一些建筑工人进行听力筛查似乎是有必要的。
