摘要
城市排水管道产生的噪音会影响人们的工作和生活,也是家庭噪声的主要来源。利用一种简单的评价方法对不同的城市排水管道包扎材料的降噪性能进行分析。此种评价方法的理论依据为声学测量理论,以单层包扎的方法对材料的降噪性能进行实验,实验对象分别为隔声毡、聚氨酯、隔声毯、隔声垫、聚乙烯等。根据实验结果可知,隔声毡的降噪性能最佳,聚乙烯的降噪性能最差。
The noise generated by urban drainage pipes will affect people's work and life,and it is also the main source of household noise.This paper analyzes the noise reduction properties of different urban drainage pipes.The theoretical basis of this evaluation method is the acoustic measurement theory,and the noise reduction performance of the material is tested by the single-layer dressing method,including acoustic insulation felt,polyurethane.sound insulation blanket,sound insulation pad,polyethylene,etc.According to the experimental results,the noise reduction performance of sound insulation felt is the best,and the noise reduction performance of polyethylene is the worst.
