Airbase and/or airport noise prediction models such as the Air Force NOISEMAP computer program are used to forecast the long term noise exposure from aircraft flight and ground activity at a facility. Noise contour maps from these calculations are used to assess the potential adverse effects such noise may have on the environment and to assist nearby communities in performing compatible land use planning. To calculate the noise exposure at any specified ground position located to the side of a flight path, a variety of noise attenuation mechanisms must be accounted for if the model is to predict levels that are in reasonable agreement with field noise measurements. For such locations, the attenuation effects are usually grouped as being due to: (1) wave divergence (spherical spreading), (2) atmospheric absorption, and (3) lateral attenuation, (the combined attenuation due to ground, meterological, forward flight, and engine/airplane installation effects).
