上海化工职业病防治研究所于1981～1984年对上海化工系统所属八个公司,120家厂进行了噪声调查。本次调查为今后的噪声治理提供了依据。据统计120家厂中已有49家对191个声源进行了噪声治理。减噪值最低为5dB(A),最高为34.5dB(A),但由于采用方法或材料选择、布置不妥当或不合理,效果仍不够理想,有待进一步改进。对目前治理有困难者,建议采用个人防护措施,如佩带耳塞或耳罩。
Shanghai Institute of Chemical Occupational Disease Prevention in 1981 to 1984 on the Shanghai Chemical Industry System owned eight companies, 120 factories conducted a noise survey. This investigation provides the basis for noise control in the future. According to the statistics, 49 of 120 factories have conducted noise management on 191 sound sources. The lowest noise reduction value is 5dB (A) and the highest is 34.5dB (A), but the result is still not satisfactory due to the improper or unreasonable arrangement of methods or materials, which needs further improvement. For the current management difficulties, it is recommended to use personal protective measures, such as wearing earplugs or earmuffs.
