NVH testing

Boost efficiency in every step of the noise, vibration and harshness (NVH) measurement process.

Why is noise, vibration and harshness important?

Noise, vibration and harshness are all characteristics passengers experience that shape their perception of quality in your vehicle. Too much of one of these, or the wrong “note” can mean negative reviews and impact future sales. So it’s no wonder why manufacturers devote so much time and resources towards optimizing NVH in their vehicles to improve customer perceptions. But do you have the right equipment and software for efficiently evaluating NVH performance?

Enhance productivity in your NVH measurement campaign

NVH test engineers face the dual challenge of reducing time-to-market and development costs while ensuring quality and completeness. Limited prototype availability and testing time further complicate their work, demanding increased efficiency in product validation. In this challenging environment, they must evaluate multiple test conditions and applications while still meeting the highest standards.

Simcenter provides dedicated solutions for NVH teams to optimize NVH testing campaigns. Combine scalable acquisition hardware with our measurement, processing and analysis software to make NVH assessments more cost-effective. Simcenter’s intuitive and scalable NVH testing solutions enable efficient measurement, analysis, reporting and data sharing. They support a wide range of NVH activities at different stages of the development cycle, from troubleshooting to high channel count multi-physics performance testing campaigns.
