| 摘 要： | 目的探讨中小化工企业中低频噪声对接触者听力损伤情况,为中低频噪声防护措施提供依据。方法测量12家中小化工企业工作场所职业性噪声强度和频谱,并对接触噪声的212名工人和对照组179名工人进行纯音听力检查。结合现场噪声监测结果分析工人听力损伤特点。结果该工作场所工人接触噪声主频率为中低频稳态噪声,噪声强度为72.4~96.2 dB(A);观察组中频高段和语频听力损失检出率分别为42.9%和20.8%,均高于对照组〔中频高段(2χ=121.61,P0.01);语频段(2χ=52.64,P0.01)〕。观察组不同频段听力损失值均高于对照组(F=9.6,P0.01)。结论中低频职业噪声对接触者听力产生危害,应尽快制定防护措施。
