Abstract:

This paper describes how an acoustical study has been conducted at Ronald Reagan Washington National Airport in order to assess the modeling of aircraft noise that propagates over water. The primary objective of this study was to evaluate NoiseMap7’s calculation of noise propagation over water for single noise events, and to determine the program’s validity of representing the surface of the water as an acoustically hard surface. Based on the physics of noise propagation actual sound levels are expected to be higher than estimated levels from noise models that assume a soft ground cover. The inclusion of topography should improve the accuracy of the estimated noise levels. The basic physical explanation is that the water surface is acoustically hard as opposed to the assumed acoustically softer ground cover and no absorption occurs. This paper describes the field collection data and methodology, and the results of the comparison of measurement data with NoiseMap7 calculations.
