金属管道噪音控制及防噪音厚度计算

摘要

This article introduces the principles of noise control and puts forward the means for noise control in metallic piping. It also introduces an empirical formula of noise insulation thickness and expatiates on how to use this formula with examples and issues to be noticed. The paper analyses the impact of noise frequency, diameter of piping and installation and so forth on noise control. The purpose is to find out an applicable method to calculate the acoustic insulation thickness of metallic piping and achieve a desired effect of noise control.%介绍了噪音控制原理,提出了控制金属管道噪音的方法.引入了计算金属管道防噪音厚度的经验公式,并举例说明对该公式的使用以及应当注意的问题.分析了噪音频率、管道直径以及噪音控制施工等因素对噪音控制的影响.目的是为金属管道防噪音厚度的获取寻找一种可行的方法,并达到满意的噪音控制效果.
