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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
