As automotive systems become quieter and more sensor-driven, accurately simulating sound behavior has become critical.
In this article, COMSOL highlights how acoustic ray tracing combined with GPU acceleration is transforming automotive acoustics simulations. By pairing finite element methods (FEM) for detailed sound sources with ray tracing for high-frequency propagation, engineers can model complex scenarios such as ultrasonic parking sensors and cabin acoustics more efficiently.
The introduction of GPU support in the Acoustics Module delivers performance gains like cutting simulation times from hours to minutes, making high-fidelity, broadband acoustic analysis faster, more practical, and better suited for modern automotive design cycles.
