Bringing Sound and Vibration Data to Life

How do you know what the complete vehicle will actually sound like when you look at plots, graphs and numbers from CAE results, targets and component-level measurements?

How do you effectively communicate the impact of NVH design decisions and options to decision makers?

How do you create an immersive soundscape that embodies and projects the brand’s essence, and know what the experience will be, without a physical prototype to drive?

To truly comprehend NVH data, it needs to be experienced as sound and vibration. But how do you bring together data from many sources, in different formats, and for multiple components, and assemble a single digital virtual prototype that can be listened to, felt and driven interactively?

VI-NVHSim software brings NVH data to life by immersing users in sound and vibration experiences, fostering a comprehensive understanding of the vehicle's acoustic landscape.

It fuels all VI-grade NVH Simulators, spanning DESKTOP, COMPACT, COMPACT FSS, STATIC, On-road, Exterior, and full-motion DYNAMIC Simulators. Moreover, VI-NVHSim functions as a standalone tool on laptops, facilitating model preparation and analysis independently of simulator hardware.

As an open platform, it seamlessly integrates with third-party applications, including sound design toolsets, vehicle performance models, SiL, and HiL applications. Its versatility extends across various simulator types, ensuring a flexible and encompassing approach to NVH simulation and analysis.

VI-NVHSim seamlessly connects in real-time to other VI-grade software solutions, including VI-DriveSim, VI-WorldSim, and VI-CarRealTime, along with Simulink and other real-time software solutions.

This capability facilitates the integration of real-time performance models, accommodating driving simulators of varying sizes and configurations. The software supports multi-attribute simulation, mirroring the capabilities of VI-grade FSS simulators.

Widely adopted by major automakers and recognized as the de facto standard for NVH design and experiential simulation, VI-NVHSim has become the industry standard for designing and refining the sound and vibration characteristics of vehicles.
