Cabin Comfort: Predicting & Reducing Car Interior Noise with Aeroacoustics Simulation

Design quieter vehicles from the start.

Aeroacoustics Simulations of Full-Scale Sedan Vehicle Towards Interior Noise Predictions (Ref. AIAA-3825), developed in collaboration with Honda Motor Co., demonstrates how cutting-edge CFD techniques can identify and address sources of wind noise before a vehicle ever hits the road.

As electric vehicles replace combustion engines, wind noise is emerging as the leading contributor to cabin sound levels. This study shows how Large Eddy Simulations (LES), powered by our low-Mach (Helmholtz) Fidelity LES Solver (formerly Cascade CharLES), can transform the early stages of vehicle design for superior cabin comfort.

Key Takeaways from the Study:

  • Advanced Simulation Accuracy – Capture both hydrodynamic and acoustic pressure fluctuations impacting cabin noise.
  • Real-World Correlation – Simulations validated against Honda wind tunnel testing to pinpoint high-noise areas such as side windows and A-pillars.
  • Faster Insights – Achieve significant simulation speed-ups using GPU acceleration, enabling rapid design iteration.

Presented at AIAA AVIATION 2023 Forum, this work represents the next step in predictive, simulation-driven vehicle noise reduction.
