Abstract: The goal of acoustic source modeling for auralizations is to determine source signals and corresponding directivities of technical or environmental noise sources. In the presented approach, a source model of vehicle noise emissions is derived from pass-by measurements by inverse calculation of sound propagation effects. The processing chain compensates on recorded data for the source distance, the Doppler effect as well as atmospheric absorption and ground effect. The emission model can be applied in traffic noise auralizations of virtual urban scenarios and research on well-being and comparison studies of urban soundscapes.
