摘要 根据某高档住宅小区冷却塔辐射噪声的测量数据,应用有限元分析方法分析了冷却塔的声场分布云图,分析了冷却塔的主要噪声来源和频带特性。分别从吸声、消声和隔声三个方面制订噪声控制的方案,所有降噪设施不但考虑防尘、防潮,而且满足设备相应的风量和温度要求,噪声控制取得了良好的效果。 According to the measured data of a high-grade residence area, plots the sound field chart using the finite element analysis, and analyses the noise source and frequency characteristics, Studies noise reduction projects from the aspects of sound absorption, attenuation and insulation, taking account of dust proof and damp proof and in the meantime the air volume and temperature can be satisfied. The effect of noise control is satisfactory.
