摘　　要：以某小区冷却塔的噪声治理为例,通过对其噪声数据的测量,详细分析了冷却塔噪声的主要来源和特性,并从消声、吸声、隔声等方面阐述了一种实用的控制措施。结果表明,此方案不仅降噪效果明显,而且能够完全满足设备所需通风量和温度的要求,在工程实际过程中取得了良好的降噪效果。In this paper, the noise control of a cooling tower for a residence area is taken as an example to analyze the main source and the characteristics of cooling tower noise based on data measuring and also a set of practical controlling measures are elaborated in aspects of sound elimination, sound absorption and sound insulation. The result shows that not only the ef- fect of noise reduction in this scheme is evident, but also it can meet the requirements of the wind volume and temperature for the equipment. Perfect effects of noise reduction can be obtained in practical project.
