Modeling propagation of aviation noise under range-dependent conditions, using a Parabolic Equation method

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

A model for sound propagation over uneven terrain, with mixed ground impedance and range-dependent meteorological conditions has been developed to improve prediction of the impact of aviation noise on communities. Based on the Parabolic Equation method, the model is intended to enhance the noise prediction capabilities for the Federal Aviation Administration's Aviation Environmental Design Tool in support of the Next Generation Air Transportation System (NextGen). The model ensures the low frequency content, a factor in community impact, is propagated accurately and can accommodate broadband, moving sound sources, traveling along user-specified paths, over three-dimensional terrain. Two test cases including uneven terrain, an impedance discontinuity, and a downward refracting atmosphere were designed to represent simple but realistic propagation conditions. Model results for a source traveling along a simple flight path under the conditions of the two test cases are presented and compared.
