The Office of Noise Abatement, Department of Transportation, has developed several models for estimating transportation system sound levels. In this study, the models were exercised to obtain community sound levels which were compared with measured levels. The Motor Vehicle/Highway System Noise Model was used to estimate the sound levels at measurement locations adjacent to and in the line-of-sight of major traffic thoroughfares. The average absolute difference between the estimated and measured median sound levels was 1 dBA. The Community Median Noise Level Model is shown to be accurate to within plus or minus 3 dBA. It is recommended that the relationship between the Noise Pollution Level and community reaction to transportation noise be validated through a social survey. Once the relationship between NPL and subjective response has been validated, the NPL should be computed for major urban and suburban areas, in order to obtain an estimate of the magnitude of the transportation noise problem in the United States.
