title: The effect of a proposed transportation facility on noise levels in a suburban community.
abstract: A nine month study of current noise levels was made at twenty-two sites within a community in Eastern Pennsylvania to evaluate the noise pollution factors for a proposed highway. An attempt was made to correlateamnient noise levels for each day of theweek with each location. Computer programs were utilized for datareduction, statistical calculations, and prediction of future noise levels. The prediction analyses were composed of contour analyses, sensitive receptor sites analyses, and the "Do Nothing" analysis. Results indicated no noise pollution problems existed during the survey, but future noise levels may exceed Federal Standards for certain sections of the proposed alignments. Factors that cause the unacceptable future noise levels are identified and modifications may be incorporated for adherence to the standards.
