Advanced NVH testing for vehicles, components and powertrains

NVH testing that improves comfort, quality and refinement

As electrification increases, noise and vibrations become more noticeable – and small deviations that were previously masked by combustion engines suddenly become clear. This means NVH issues can quickly affect customer experience, perceived quality and brand value. Many development teams work under intense time pressure, with parallel technological shifts and rising expectations for comfort and refinement. We understand that it’s not just about measuring noise and vibrations, but about understanding early on why they occur and how they affect the overall system.

In our controlled and repeatable test environments, we measure and analyse noise and vibrations from vehicles and components under realistic acoustic and vibrational conditions. The NVH platform is designed to give you clear, traceable and decision‑supporting insights – whether you work with complete vehicles, electric powertrains, subsystems, components, prototypes or customised solutions. We help you identify noise sources, understand structural behaviour and ensure that the powertrain delivers the right level of refinement.

We verify noise levels, comfort, structural behaviour and powertrain refinement, and we identify and analyse noise sources. The goal is to give you the precision and predictability needed to develop vehicles that feel quiet, stable and high‑quality – and to give your team confidence that every NVH decision is based on robust and repeatable data.

Our NVH offering

Within our NVH offering, we provide:

• Acoustic testing: Noise measurements and source identification.
• Vibration testing: Measurement of structural vibrations, powertrain and body vibrations.
• Powertrain NVH: We measure rig wall attenuation and ensure the frequency range of the measurement equipment. Mechanical noise from the shaft drive is analysed across a broad frequency spectrum.
• Noise control engineering: Enclosure optimisation and reduction of flow‑induced noise.
• Tailored NVH programmes: Test planning, prototype evaluation, design support and technical reporting.

Why choose us

SEEL – the Swedish Electric Transport Laboratory – is Sweden’s national test centre for research and development in electromobility. Here, advanced test infrastructure meets leading expertise to accelerate the development of next‑generation electric transport solutions – and to strengthen a sustainable, competitive battery value chain in Sweden and Europe.

As a SEEL customer, you gain access not only to our test infrastructure but to an entire ecosystem of complementary expertise and testing capabilities. Maximise the value of your vehicle testing by combining it with specialist competencies within SEEL and RISE, such as solar simulation, EMC testing and advanced environmental testing.

As an independent actor, we deliver objective and reliable results in modern laboratories where every test is performed in a controlled and repeatable environment. This gives you secure, comparable and decision‑supporting data that drives development forward.

Our strategic location on Hisingen in Gothenburg also provides fast and convenient access to the region’s strong automotive and industrial cluster. This means shorter lead times, proximity to the right expertise and a partner who can support you throughout the entire development chain – from concept to verified solution.
