Vehicle sound-generating system

Bruël & Kjær’s (Duluth, GA) VSound Type 3115 vehicle sound-generating system—from both interior and exterior perspectives—enables virtual NVH prototype evaluation in the context of a real vehicle, without the need for a PC in the vehicle.

According to the company, VSound delivers exceptionally high-quality audio signals—from complete engine sounds to simple looped sounds—using audio algorithms similar to those used by the Brüel & Kjær NVH Simulator. To control the sound output, VSound uses vehicle parameters such as throttle, rpm and speed from the CAN‐bus system.
