Customer expectations regarding the vibration comfort and noise behaviour of a vehicle and its interior are constantly increasing. In addition, the legislator is imposing increasingly stringent noise requirements.

We have extensive NVH consulting, development and testing expertise as well as the testing facilities to ensure our customers’ NVH goals for all drive concepts with innovative solutions from concept to series production. The offering ranges from the component level through subsystems to full NVH responsibility for the complete vehicle.

The combination of modern in-house indoor test benches and outdoor test tracks is an ideal prerequisite for the holistic consideration of vibrations and noises under test and real conditions.
