Area Computer Model for Transportation Noise Prediction: Phase II -- Improved Noise Prediction Methods

Report No: 75-R65

Published in 1975

About the report:

This report recommended that NOISE 3 initially use the same basic logic as the MICNOISE program for highway noise prediction except that additional options be made available, such as flexibility in specifying vehicle noise sources. A choice of six noise ratings was recommended, including Ldn, the day-night level then being proposed by the EPA for general use. NOISE 3 results would be posted on maps of the road network, using the XYNETICS contour program until a new contour program became available.
