VI-grade and HBK are transforming product development through Smart Testing.
The question is no longer “Should we simulate or test?” but “How do we combine them intelligently?”
Smart Testing connects virtual and physical testing through data, AI-powered analytics and integrated workflows. Simulation validates and optimizes physical tests, whereas physical data strengthens and refines virtual twins.
The result: faster decisions, shorter development cycles and smarter products.

VI-grade and HBK will take part in the 14th International Styrian Noise, Vibration & Harshness Congress, ISNVH 2026, taking place on June 17-19, 2026 in Graz, Austria. Recognized as a key European forum for automotive NVH, the congress brings together experts from industry and academia to discuss the latest strategies, tools and technologies shaping the future of noise, vibration and harshness engineering.
At the event, VI-grade and HBK will showcase how integrated simulation, test and measurement technologies can support more efficient, realistic and data-driven NVH development workflows. Visitors will be able to experience our Compact Full-Spectrum Simulator, demonstrating how virtual prototyping can help engineers evaluate, validate and refine vehicle sound and vibration performance earlier in the development process.
VI-grade will also contribute to the technical program with this workshop: “Active Sound Design: Virtual Prototyping and Validation with NVH Simulators,” chaired by Giorgio Adriano, with representatives from Jaguar Land Rover, DSP Concepts – Audio Weaver, BlackBerry QNX and Bose Automotive. The workshop will explore how NVH simulators can support active sound design workflows, from virtual prototyping through validation.
