Noise control techniques for existing power plants

This paper provides guidelines for the selection and application of appropriate noise control techniques for equipment located in existing power plants. Several noise reduction techniques, the scientific principles involved, and the major devices utilized with each technique are listed and discussed. Possible sources of power plant noise are identified and possible methods of noise reduction are given. The selection of the most appropriate method for a particular piece of equipment can only be determined by an engineering analysis of each noise problem with careful consideration given to the economic feasibility as well as the effects on operation and maintenance of the equipment involved.
