工业噪声控制除应满足《工业企业噪声卫生标准》外，还应满足《城市区域环境噪声标准》。本文主要讨论如何依据这两个标准测算设备降噪量；如何依据降噪量要求选择经济实用的降噪方法和噪声治理方案，以达到优化控制的目的。
Industrial noise control should meet the “noise level of industrial enterprises,” but also meet the “urban area environmental noise standards.” This paper mainly discusses how to measure the noise reduction of the equipment according to these two standards. How to choose an economical and practical noise reduction method and noise control scheme according to the requirements of noise reduction so as to achieve the purpose of optimal control.
