我国纺织噪声暴露现状及听力损失情况预测

Prediction on exposure status and hearing loss of spinning noise in China

通过对国内纺织业从业人员数量、工龄的统计和企业实地噪声情况的调查,借鉴ISO1999-1975(E)和其它相关方法预测我国纺织行业噪声暴露情况和从业人员的听力损失情况。经过预测,结果显示纺织从业人员暴露于85dB以下噪声的约有289.3万人,85～95dB约有381.2万人,高于95dB约有329.5万人;对于听力损失的预测,采用悲观和乐观法分别进行预测,结果表明约有100.57万人和21.61万人患有听力损失;结合实际调研情况对预测数据进行修正,结果表明目前我国纺织行业约有70.96万人患有听力损失。

According to statistic for quantity of domestic textile industry workers, length of service and survey for noise of local company, the situation of noise exposure and employees＇ hearing loss were predictied base on ISO1999 -1975 （E） and other related methods of prediction. The results indicated that there were about 2,893, 000 spinners＇ exposure to noise below 85 dB, about 3,812,000 people exposure to noise between 85 and 95dB, and 3,295,000 people exposure to noise higher than 95dB; for hearing loss prediction, by pessimistic and optimistic prediction method, the results showed that about 1,005,700 people and 216,100 people suffering from hearing loss respectively. In light of the actual collected data to amend the results showed there were about 709,600 spinning workers suffering from hearing loss in China＇s textile industry.
