Abstract
A set of computer programs, called Integrated Noise Model (INM), has been developed to compute noise exposure values due to aircraft at various locations around airports. The INM evolved from an earlier computer model used for investigating noise around 23 U. S. airports in terms of NEF. The INM consists of three independent routines: (1) Contour Analysis Model, (2) Grid Analysis Model, and (3) Contour Plotting Pack.age. INM will compute noise exposure values for the following: Noise Exposure Forecast (NEF); Day—Night Average Sound Level (Ldn); Community Noise Equivalent Level (CNEL); Aircraft Sound Description System (ASDS); and Daily Overall Sound Exposure (DOSE, an experimental noise metric). The calculations are sensitive to details of fleet mix data and flight operational procedures. The Contour Analysis Model develops points on curves of equal noise exposure. The Grid Analysis Model computes exposure levels at user‐specified points. Optional output allows examination of the noise contribution from each flight. The Contour Plotting Package retrieves contour point locations from mass storage and plots them. [Work supported by U. S. Department of Transportation.]
