NVH automotive engineers used to spend their whole career on reducing noise and vibration issues. The job is to come up with counter measures to remove or reduce these issues, leading to better performance, durability, and/or comfort. Digital twins have become very instrumental to validate design improvements without requiring physical prototypes. With vehicle electrification we enter the era where the powertrain is no longer the biggest contributor to interior and exterior noise. This makes that NVH engineers now must start adding sound to their vehicle designs again. That domain is called Active Sound Design and resides in between several domains: NVH, audio, and design. This paper explores how Active Sound Design (ASD) can benefit from the Digital Twin approach.
