- 摘要:
- 建筑管道排水噪声是室内主要噪声源之一，为研究不同材质和不同管道包裹方式对排水管道噪声的影响，对硬聚氯乙烯 （UPVC）管和铸铁管两种材质管道马桶排水噪声进行现场测试，并测试管道在不同材料包裹下的降噪效果，用于指导实际工程应用。测试结果表明，不同包裹状态下铸铁管的排水噪声值较UPVC管低9~11 dB，包裹管道后排水噪声均表现为明显的低频特性。玻璃棉对管道排水噪声平均值和最大值的改善量均大于11 dB；阻尼隔声毡对管道排水噪声平均值的改善量大于8 dB，对最大值的改善量低于3 dB，在进行管道降噪时，建议考虑排水噪声最大值的影响。
- Abstract:
- Drainage noise from building pipelines is one of the main indoor noise sources. To investigate the effects of different pipe materials and different wrapping treatments on drainage pipeline noise, field tests were conducted on the flushing drainage noise of unplasticized polyvinyl chloride（UPVC） and cast iron pipes. The noise reduction performances of different wrapping materials were also tested to provide guidance for practical engineering applications. The test results showed that the drainage noise of cast iron pipes under various wrapping conditions was 9-11 dB lower than that of UPVC pipes. After wrapping, the drainage noise of both types of pipes exhibited obvious low-frequency characteristics. Glass wool could reduce both the average and maximum drainage noise levels by more than 11 dB. Damping sound insulation felt could reduce the average drainage noise level by more than 8 dB, but its reduction of the maximum noise level was less than 3 dB. Therefore, when implementing pipeline noise reduction measures, it is recommended to consider the impact of the maximum drainage noise value.
