职业噪声是工业厂房的主要环境问题之一。因此,为了限制高水平职业噪声,国际标准组织(ISO)、EEC和其他发达国家已允许最大允许职业噪声暴露限值在90-85 dB(A) L-eq范围内,持续8小时/天(40小时/周)。但在发展中国家,大多数工厂的工作时间为每天 8 小时、每周 6 天,即每周 48 小时。对于此类植物,需要设定不同的限制;建议将每天 8 小时和每周 48 小时的 L-eq 限值限制为 88 dB(A),减半率为 3 dB(A)。 (C) 1998 Elsevier Science Ltd. 保留所有权利。
Occupational noise Is one of the major environmental problems in industrial plants. Therefore, in order to limit high level occupational noise, maximum permissible occupational noise exposure limit in the range of 90-85 dB(A) L-eq for 8h/day (40 h/week) have been allowed by the International Standards Organization (ISO), EEC and other developed countries. But in developing countries, most of the industrial plants work for 8 h/day and 6 days/week, i.e. 48 h/week. For such plants these is a need to set a different limit; a limit of 88 dB(A) L-eq for 8 h/day and 48 h/week with halving rate of 3 dB(A) is being proposed. (C) 1998 Elsevier Science Ltd.
