NOISE CONTROL OF WATER COOLING TOWERS IN ROME'S HOSPITAL AREA

摘要

The study concerns a noise impact prediction, in order to establish compliance according to the contract of new water cooling towers that will be installed following the completion of a modern central cooling subservient at the General Hospital "A. Gemelli" in Rome. To characterize the existing cooling towers of the refrigeration unit, and to detect the residual noise of the area, sound level measurements were carried out during the night. These samples, together with the sound emission data of the new sources (certified by the manufacturer), were used in order to build the prediction noise Scenarios using "CADNA" software and other appropriate algorithms.
