The authors analyzed 255 cases of occupational hypacusia reported as occupational diseases in 1962-1988 in the Czechoslovak uranium industry. Up to 1975 occupational hypacusias accounted for 9-11% of the nationwide number of hypacusia notified as occupational diseases. Due to extensive social provisions, incl. preventive ones, the incidence declined since 1985 below 1% of the nationwide incidence. The group of 255 men with occupational hypacusia was examined in detail at the Health Centre of the Uranium Industry in Príbam. Their age is 49.0 +/- 8.5 years, noise exposure 14.6 +/- 5.8 years, the the ratio of miners is 82.4%, the total percentage hearing loss is 63.5 +/- 11.4%, the mean annual increment of the total percentage hearing loss is 4.8 +/- 0.6%, the greatest mean annual increment is 5.4% in the occupation of miners.
作者分析了捷克斯洛伐克铀工业1962年至1988年报告为职业病的255例职业性听觉减退病例。截至1975年，职业性听觉减退占全国报告为职业病的听觉减退病例数的9%至11%。由于广泛的社会福利措施，包括预防性措施，自1985年以来发病率降至全国发病率的1%以下。对普日巴姆铀工业健康中心的255名患有职业性听觉减退的男性进行了详细检查。他们的年龄为49.0±8.5岁，噪声暴露时间为14.6±5.8年，矿工比例为82.4%，总听力损失百分比为63.5±11.4%，总听力损失百分比的年均增量为4.8±0.6%，矿工职业的最大年均增量为5.4%。
