围绕某燃气热电厂噪声污染治理工程，介绍项目的声源分析过程、降噪措施的设计思路以及实施效果，为类似噪声治理工程提供经验借鉴。为控制工程成本，本项目结合工程实际情况，采用分阶段实施降噪措施，先对最主要的噪声污染源进行治理，根据效果再对次要的声源进行治理，避免出现一些不必要的降噪措施，也避免一次性投入大量资金，获得非常良好的工程效果和经济效果。%This paper focus on a gas-fired power plant noise pollution control projects, including sound sources analysis, the design ideas and implementation effect of noise reduction measures. The noise control engineering was carried out by 2 subphases to control the engineering cost. The most importance noise sources were priority treated in first subphase. Then the noise control of first subphase was measured and evaluated. Then the second subphase was design according to the actual result of first subphase to avoiding the wasting of noise control measure. A very good engineering and economic effects was obtained in this engineering and it could be referenced for the similar Noise Control Engineering.
