多层公建屋顶的多机组降噪措施——以安徽省农村信用社联合社为例

Noise Reduction Measures for Large Public Buildings with Multiple Units--A Case of Anhui Rural Credit Cooperatives Union

在公共建筑屋顶出现的多种设备综合运行时,所产生的噪声对周围环境影响较大。以安徽省农村信用社联合社为例,建筑屋顶上存在的多种产噪设备,经过一次设备降噪处理后,依然未能满足声环境的标准时;则应采用二次降噪的手段来改善周围的声环境,使其达预期的目标。同时,利用Cadna A软件模拟验证结果,对其他出现大量产噪设备的建筑进行噪声控制起到参考作用。

In the comprehensive operation of various equipment on the roof of public buildings,the noise produced has a great influence on the surrounding environment.Taking Anhui Rural Credit Cooperatives Union as an example,there are many kinds of noise production equipment on the roof of the building.After the primary equipment noise reduction treatment,it still fails to meet the standard of sound environment.The secondary noise reduction is used to improve the surrounding sound environment and achieve the desired goal.Meanwhile,the Cadna A software is used to simulate and verify the results,which provides a reference for noise control in other buildings where a large number of noise-producing equipment is present.
