对于我国现有的建筑物来说,许多年代较早的已建成建筑物都没有考虑到排水管道噪声给人们的居住环境带来的困扰。对于这种建筑为避免其噪声问题,进行排水管道的全部改造显然是不可行的,利用声学材料隔声包扎是一种有效、快速、经济的解决方法。本文利用电声学实验进行了声学材料与管材的组合包扎,分析了管材在不同频段的最适宜包扎材料,根据排水噪声特性选出最佳降噪材料。
For our country’s existing buildings, many of the older buildings have not taken into account the drainage pipe noise to the people’s living environment troubles. For this kind of building to avoid its noise problem, it is obviously not feasible to carry out all the reconstruction of the drainage pipe. The use of acoustic materials for acoustic bandaging is an effective, rapid and economical solution. In this paper, electro-acoustics experiments were carried out with the combination of acoustic material and pipe banding. The optimum banding material for pipe in different frequency bands was analyzed. The best noise-reducing material was selected according to the drainage noise characteristics.
