In a recent publication, we presented an efficient method to find eigenrays in a stratified, moving medium. The simulation framework is designed to auralize aircraft flyovers. However, the method is restricted to the direct sound and a ground reflection. When dealing with flyover scenarios close to residential areas, the interaction of sound with urban structures, especially reflection and diffraction, should be considered. Typical models for auralization in urban areas in fact do consider those interactions but neglect the inhomogeneity of the atmosphere. Thus, in this paper, the two models are combined in an approach to link between atmospheric models using curved propagation paths and urban models using straight paths but handling structure interaction.
Key words: Outdoor sound propagation / Aircraft noise / Urban environment / Auralization / Open-source
