Traffic noise in urban environments constitutes a significant health hazard, creating potential for proactive noise management and auralization as tool for modern urban planning. However, state-of-the-art raybased Geometrical Acoustics (GA) models utilized in current auralization pipelines struggle to predict the sound propagation across grounds featuring varying acoustic properties, known as Impedance Discontinuity (ID). Relying just […]

Traffic noise is an important public health issue and factor of annoyance. Auralization enables its perceptual evaluation in virtual environments. In outdoor sound propagation simulations, however, geometric modeling often focuses on large-scale features, while smaller roadside structures are neglected or simplified. For vehicle noise sources located close to the ground, roadside structures of similar height […]
