The noise exposures of 274 printing production workers in 34 establishments in the New York city area were monitored. Results showed that 43% were exposed to 8-hr time-weighted average (TWA) noise exposures of 85 dBA or greater and that 14% were exposed to 8-hr TWAs of 90 dBA or greater. Within the press department, web press workers were exposed to significantly greater mean 8-hr TWAs than sheetfed press workers. In general, a greater percentage of the workers in the bindery departments were exposed to potentially harmful noise than workers in the press departments. Results of this study indicate that many workers in the printing industry may be at risk of occupational hearing loss. Further research is needed to determine the extent of hearing impairment in this group of workers.
对纽约市地区34家企业的274名印刷生产工人的噪声暴露情况进行了监测。结果显示，43%的工人8小时时间加权平均（TWA）噪声暴露达到85分贝或更高，14%的工人8小时TWA噪声暴露达到90分贝或更高。在印刷部门中，轮转印刷工人的8小时平均TWA显著高于单张纸印刷工人。总体而言，装订部门中接触潜在有害噪声的工人比例高于印刷部门的工人。这项研究结果表明，印刷行业的许多工人可能面临职业性听力损失风险。需要进一步研究以确定这组工人的听力损伤程度。
