Unveiling advanced techniques for vehicle HVAC noise simulation

While HVAC systems play a crucial role in ensuring thermal comfort, they often introduce acoustic discomfort as a trade-off. Especially in electrified vehicles, HVAC noise is more audible as its silent electric motor doesn’t mask unwanted noises. Achieving a balance between cabin comfort, thermal performance, and acoustics is essential for enhancing the overall customer perception of the vehicle.

This webinar looks at the impact of flow-induced noise on the acoustic comfort of the passenger. It focuses on methods to reduce simulation time while maintaining accurate prediction of the noise source. Register now!
