In‐vehicle Virtual NVH Prototype Evaluation System
-
VSound is an in‐vehicle virtual NVH prototype evaluation system
The heart of the VSound system is the VSound DSP Box. The DSP Box connects to the vehicle CAN‐bus system for parameters such as vehicle speed, engine and/or motor rpm, pedal position, gear selection, and other parameters as needed. One to eight outputs are then sent to the existing audio system of the vehicle or a completely separate set of speakers or dynamic actuators.

USE SCENARIOS
- Development of appropriate interior and exterior sounds for electric and other quiet vehicles
- Evaluation of any potential interior or exterior vehicle sound design in the real world:
- Back‐to‐back NVH comparison of benchmark vehicles in one vehicle
- Presentation of exterior sounds of differing complexities to define production hardware requirements
- Design of discrete sources on an IC vehicle to create distinctive exterior sound quality
VSound uses vehicle parameters such as throttle, rpm and speed from the CAN‐bus system, enabling the user to switch between a series of predefined vehicle sound profiles.
