TRANSPORTATION NOISE POLLUTION APPENDIX G, ANALYTICAL MODEL FOR ESTIMATING AMBIENT NOISE LEVELS

This appendix presents an analytical model for determining steady-state noise level by averaging metropolitan noise over large areas for extended periods of time. The model is based upon the following facts: metropolitan noise sources can be separated into transportation noise, industrial noise, and other assorted noises; transportation noise is the overwhelmingly predominant noise source; and of the various types of transportation noise, traffic noise is responsible for the ambient noise levels and the vast majority of disturbances in most metropolitan areas, even in areas that contain major airports. Finally, traffic noise can in turn be considered, for the purpose of determining ambient noise levels, to be composed of the noise from cars, light trucks and heavier trucks.
