Abstract

The USAF NOISEMAP computer program predicts noise exposure contours around airbases from input information about aircraft types, operations, and flight paths. The program uses measured noise data together with standard propagation equations to compute the contribution to the sound pressure level at a given grid point for each aircraft as it flies along its flight path. All contributions are then combined to predict an overall equivalent noise exposure level, such as the day-night sound level, LDN, for each grid point. A contouring subroutine is used to produce a LDN contour map of the airbase vicinity. An experimental validation study indicates excellent agreement between predicted and actual LDN values.
