18-27: Cooling Tower Sound: Data Comparisons and Recommended ImprovementsCTIs ATC 128, Europes ISO 3744 and Chinas GB T 7190 are test codes which describe methods to measure sound pressure levels from water cooling towers to compute sound power levels. In accordance with these codes, our engineers collected sound pressure measurements on a variety of factory assembled cooling towers of different types and shapes and computed the sound power levels. The data collected and the results of calculations from the different
