噪声治理技术实例研究

文章从噪声源入手,分析泵房和压缩机房内的噪声对工作人员和居民不同程度的影响和危害,按照噪声控制的原理,采取吸声、隔声、消声相结合的降噪措施。治理后,泵房、压缩机房内噪声值低于85 dB(A),压缩机房厂界噪声值低于60 dB(A),居民楼外1 m处的噪声值低于45 dB(A),有效减少噪声对作业场所和周边环境的污染。

A Case Study on Noise Control Technology

This paper,starting from noise sources,analyzes the different levels of impact and danger to the staff and residents imposed by the noises of the pumping room and the compressor room.In the light of noise control principle,noise control measures combined with noise absorption,noise insulation,noise elimination are adopted.After treatment,the noises of the pumping room and the compressor room are lower than 85 dB (A);1 meter beyond the residential buildings are lower than 45 dB(A);the border of the compressor room are lower than 60 dB (A);therefore it effectively reduces the noise pollution to the operation site and the surrounding environment.
