摘　　要：以某高档商务酒店式公寓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,为工程实际中冷却塔的噪声治理提供了借鉴,具有指导意义。In this paper the noise control of a high- grade residence traders hotel type cooling tower is selected as an example. On the base of measuring data, the noise resource is analyzed and the character of the noise resource is discussed. In aspects of sound eliraination, sound absorption and sound insulation, a set of practical controlling measures are elaborated. The result shows that the noise reduction effect of this scheme is obvious and also it can fully satisfy the requirements that the equipment needs for the wind volume and temperature, which provides references for the noise control of the cooling tower in engineering practice and has a guiding significance.
