Abstract:

This report delineates the program operator changes consistent with the additional developments made on the computer program described in AMRL-TR-73-109 AD-A004 821. The added capabilities and improved diagnostics that form NOISEMAP 3.2 are discussed. NOISEMAP 3.2 is used Air Force-wide to compute community noise exposure from aircraft flying and ground runup operations for preparingassessing candidate Environmental Impact Statements and planning compatible land use in the vicinity of air installations. Improvements made to NOISEMAP include 1 Optional outputs in terms of day-night average sound level, noise exposure forecast, and these measures with tone correction and ground runup penalty weightings 2 Optional contour plotting on a line printer when sophisticated contour plotting software and hardware are not available 3 Optional capability to perform the noise exposure computations over limited areas rather than the entire airbase vicinity 4 Computation of the area contained within specified noise exposure contours 5 Variable grid spacing of the computations to provide sufficient data points in high gradient noise exposure regions and 6 Plotting of the aircraft altitude profiles to aid in checking the input operational data.
