某油田钻井作业工人听力损失状况分析

目的通过对某油田钻井公司作业环境生产性噪声暴露的测量以及作业工人的听力检查,探讨钻井行业噪声对钻井作业工人听力的影响。方法对钻井公司作业环境进行噪声监测。用纯音听力计检查噪声组483名钻井作业工人和对照组491名后勤工人的听力并分析检查结果。结果本次调查检出高频听力损失率为28.40%,噪声组在高频及语频听力损失检出率均高于对照组(P<0.01);经χ2趋势检验,随着工龄的增加,钻井作业工人高频听力损失检出率有增加的趋势(P<0.01);随着累积噪声暴露量(CNE)的增加,高频听力损失检出率也有增加的趋势(P<0.01)。结论该油田钻井作业工人听力有明显损失,应积极采取一、二级预防措施来保障工人的健康状况。

Analysis on situation of hearing loss in noise-exposed drilling workers in some oilfield

Objective To explore the effects of productive noise on hearing of drilling workers in some oilfield.Methods The noise levels in workplace of the oil drilling company were detected systematically,meanwhile,the hearing of 483 noise-exposed workers and 491 workers without noise exposure were examined by pure tone audiometer.Results The results showed that the incidence of hearing loss in these noise-exposed workers was 28.40%,the rates of hearing loss in both high frequency and language frequency were significantly higher than those of control group(P<0.01);The χ2 tend test suggested that the incidence of high frequency hearing loss showed some rising trend along with the noise-exposed length and the cumulative noise exposure(CNE),the difference was statically significant(P<0.01).Conclusion The hearing of drilling workers already injured by the productive noise,it is necessary to take active preventive measures immediately for protecting workers,health.
