摘　　要：冷却塔的噪声污染正成为当今亟待解决的问题。本文对新开发的冷却塔落水消能降噪装置在模拟自然通风冷却塔的条件下的降噪效果进行了研究,结果表明,采用该降噪装置,在淋水密度为4～16t/(m2·h)的范围内,冷却塔的噪声可降低15dB以上,降噪装置主要是削减了声源中的高频成分。The noise pollution of the cooling tower is becoming a serious problem that needs solving urgently. A newly developed cooling tower noise suppressor was studied under the condition of simulation of natural ventilation cooling tower.When water spray density were 4～16 t/(m2·h),the reduction of noise of cooling tower exceeded 15 dB.Noise suppressor mainly killed high frequency parts of the sound source.
