Road Traffic Auralization: Modeling and Synthesis of Electric Drives
54º Congreso Español de Acústica — Tecniacústica 2023
Abstract
Nowadays, road traffic emissions are dominating urban sound. Beyond the scope of objective noise assessments based on weighted sound pressure levels, the consideration of the sound generation and propagation from different traffic noise sources is a future-oriented research aspect in the urban planning process. Auralizations can be used to simulate spatial sound fields in virtual environments and thus enables an assessment of perception-related environmental noise aspects. To achieve physically meaningful and perceptually plausible auralizations, individual sound sources must be precisely characterized and modeled. At the example of the increasingly important sound emission from electric drives to the urban soundscape, this paper presents a combined method for modeling and synthesizing electric drive sound radiation. A particular focus of this work is a computationally efficient implementation using C++ and its integration to a real-time road traffic sound synthesis tool.
