Targeted engineering of acoustics, NVH and driving feel
NVH engineering as an integral part of vehicle design – across powertrain, controls, and structure
With electrification and software-defined vehicle architectures, noise and vibration phenomena arise from complex system interactions. Traditional, component-based development approaches fall short in this context. NVH issues often only become apparent at a late stage—when degrees of freedom are limited and corrections lead to compromises in comfort, sound quality, and overall performance.
That is why we treat NVH development as an integral part of vehicle design. From the concept phase onwards, we shape acoustic and vibrational behavior—based on a deep understanding of control algorithms and the targeted use of active and passive measures. This is how we develop vehicles with precisely tuned sound and driving feel.
Why proactive NVH is critical
- For development
Avoidance of late iterations and validation risks – enabling stable programs in terms of timing and cost. - For the product
Comfort, sound quality and performance are deliberately engineered and remain consistent across all use cases – instead of being compromised by late-stage fixes. - For decision-making
Clear NVH targets as a basis for architecture, component and control decisions – before incorrect assumptions become embedded.
