The audiograms of 218 coalminers were studied and it was found that 37.7% had hearing losses attributable to noise. Based upon sound level measurements and duration of exposure the risk of hearing loss in mining can be also predicted and its statistical probability and its risk measured.
对218名煤矿工人的听力图进行了研究,发现37.7%的人有因噪音导致的听力损失。根据声级测量和接触时间,还可以预测采矿中听力损失的风险,并测量其统计概率和风险。
