New vehicle sound-generating system developed by Brüel & Kjær

0

Brüel & Kjær has launched VSound Type 3115, a vehicle sound-generating system – from both interior and exterior perspectives – that enables virtual NVH prototype evaluation in the context of a real vehicle, without the need for a PC in the car. This system can be used to evaluate targets, candidate sounds and sound delivery strategies.

VSound provides high-quality audio signals – from complete engine sounds to simple looped sounds – using audio algorithms similar to those adopted by the Brüel & Kjær NVH simulator. To control the sound output, VSound uses vehicle parameters, such as throttle, rpm and speed from the CANbus system.

The multi-channel digital signal processor in the VSound system can be used to provide synchronized signals for speakers or other dynamic actuators and simultaneously generate independent sounds both inside and outside the vehicle.
