Noise from cooling towers consists of noise from several sources, each with their own characteristics, sound path, and contribution to the total sound emitted by a cooling tower at any particular receptor point. By dealing with these on an individual basis, sound prediction accuracy at plant boundaries can be increased and identification of areas for noise control can be determined. While some means to reduce sound levels a few dB have only a small impact on the tower design and cost, most modirate and greater reductions need to consider the impact on thermal performance, siting, and cost of the cooling tower.
