ccording to domestic natural gas as fuel for gas - steam combined-cycle thermal power plant characteristic, it was known that the steam turbine engine, gas turbine, waste heat boiler, mechanical ventilation cooling tower, transformer, natural gas and other areas, as well as the circulating water pump room, water plant and other auxiliary equipment room are the main noise radiation zone. The analysis on these region acoustic source equipment and the acoustic source characteristic was carried out simultaneously. Specific control measures to the key source of regional noise were put forward

Analysis of Noise and Vibration Pollution and Its Control Measures of a Stamping Workshop
LIANG Chang-de;AN Xue-li;OU Yan
   2012, 32 (3): 217-222.   DOI: 10.3969/j.issn.1006-1355.2012.03.049

The noise and vibration of a stamping workshop were tested and analyzed. The contribution of the punch noise to the factory boundary and the sensitive point (residential building) was calculated. The overall amount of noise reduction was determined. According to the noise and vibration analysis, noise reduction results and the actual engineering situation, the overall control scheme and measures were put forward, and the control effect was expected. The engineering case can be as a reference for similar engineering projects.
