Keeping Power-Station Noise Within Acceptable Limits

Because the noise created by power-plant equipment has sometimes caused complaints from those working in the plants and from residents living nearby, a survey of such noise was undertaken. This paper presents the results of this survey and shows how the power-plant noise levels compare with desirable levels. Descriptions of the particular equipment that produce most power-plant noise are included along with methods of controlling these noise levels. For those who have no previous association with noise, the Appendix contains a brief introduction to the terms decibels, octave bands, sound pressure, and sound power. For those desiring more detailed data, a descriptive list of references is included.
