A Procedure for Conducting and Evaluating Noise Surveys at Gas Turbine Installations

Once a gas turbine station is put into operation, a noise survey is recommended to determine the sound levels created by the station as a whole and to pinpoint the individual levels of each major piece of equipment. The results of the survey can be used to evaluate the silencing equipment and to point out those places where additional sound treatment would be most beneficial. This paper presents a discussion of the three phases of a typical survey: Planning, Conducting, and Evaluating.
