Impact sound level contour analysis of industrial sites.

The evaluation of industrial sites, such as for nuclear or fossil power stations, often requires detailed analysis of the existing sound levels and acoustic impact of the proposed facility at each site. Such a study was performed for five potential power station sites according to the guidelines set forth by a state licensing agency with extensive site study requirements. As required by the state, ambient sound level contours, plant construction, operation and maintenance contours, and sound level impact contours were prepared for each site for the 12 required sampling periods. A variety of land uses ranging from rural to industrial-urban were included in the study. This paper summarized the techniques involved in developing and analyzing the contouring process to the various acoustic environments. [ABSTRACT FROM AUTHOR]
