Abstract:

This report describes a preliminary study of the sensitivity of noise exposure contours to various aircraft noise modeling parameters and assumptions. The study is the first step in a continuing technical assessment of the Air Force community-aircraft noise exposure NOISEMAP prediction procedure. The results indicate that the addition of a tone correction to the noise measure can result in appreciable increase in noise exposure areas, but the increase is highly dependent on the type of aircraft operations. Computation of contour areas for nine bases with and without the ground runup penalty showed how the percent of area impacted increased with increasing noise exposure level. Use of alternate algorithms for ground-to-ground propagation and transitions for air-to-ground and ground-to-ground situations is discussed.
