Noise pollution and allied health problems are seen at all ages worldwide. This is due to increase in mechanization in industries, transportation as well as home appliances produce high level of noise. Noise Induced Hearing Loss (NIHL) is common health complaint found in industrial workers. The present research work reveals the NIHL problem in workers related to saw mill and printing press in Akluj town, Solapur district of Maharashatra state. For the present study measurement of noise levels are done in saw mills and printing presses. The standard noise level value is calculated in respective locations. Noise Induced Hearing Loss (NIHL) among the workers is measured by an Audiometer. 420 workers, viz. 250 from ten saw mills and 170 from ten printing presses respectively were investigated to find out NIHL. The average noise levels in printing press and saw mill are 90.2 dB and 79.3 dB respectively. Whereas standard noise level (Leq) in above locations are 101.4 dB and 98.7 dB respectively. The average NIHL are found in 28% saw mill workers and 13% in printing press workers. It is reported that medicine treatments are not very useful for curing NIHL. Today's available tool which prevents NIHL is ear plugs and ear muffs, which are suitable for preventing NIHL problems in industrial workers.
噪声污染及相关健康问题在全球各个年龄段都有出现。这是由于工业、交通领域机械化程度提高以及家用电器产生的噪音水平过高所致。噪声性听力损失（NIHL）是产业工人中常见的健康问题。目前的研究工作揭示了马哈拉施特拉邦索拉布尔区阿克鲁伊镇锯木厂和印刷厂工人的噪声性听力损失问题。在本研究中，对锯木厂和印刷厂的噪声水平进行了测量，并计算了各场所的标准噪声水平值。通过听力计测量工人的噪声性听力损失情况。分别对来自十家锯木厂的250名工人和十家印刷厂的170名工人进行了调查，以确定噪声性听力损失情况。印刷厂和锯木厂的平均噪声水平分别为90.2分贝和79.3分贝，而上述场所的标准噪声水平（等效连续A声级）分别为101.4分贝和98.7分贝。锯木厂工人中平均有28%出现噪声性听力损失，印刷厂工人中这一比例为13%。据报道，药物治疗对治愈噪声性听力损失效果不太显著。目前可用于预防噪声性听力损失的工具是耳塞和耳罩，它们适用于预防产业工人的噪声性听力损失问题。
