Utilising Ricardo’s in-house test facilities, we can accurately measure NHV phenomena for efficient benchmarking, development testing and validation
Facilities comprise three powertrain semi-anechoic test cells, vehicle anechoic test facility (modal analysis room, vehicle workshop and semi-anechoic chassis dyno) exterior noise track and listening room (multi-media suite).
The RAS-R system provides electronic augmentation of internal combustion or electric power unit sound quality using live streaming authentic sound sources, rich in genuine information content.
The live authentic sound linked directly to the xEV powertrain to deliver an interior driver experience in line with brand expectation, whilst ensuring exterior pedestrian safety requirements are met. The system integrates multiple authentic sound layers to build a sound signature that signals the cars operating status.
Within the rail sector, we provide clients with NVH support and analysis from early design stages through to emerging in-service issues. Previous assignments include helping a global rolling stock manufacturer comply with noise and vibration regulations in local markets, and advising the US Federal Railroad Administration on comparitive international high-speed noise reduction measures.

Why Ricardo for noise, vibration and harshness solutions?
Well defined processes
With over 40 years of NVH testing experience, Ricardo has developed well defined processes for hybrid and electrified vehicle and powertrain NVH analysis, drawing on gained experience to support the needs of clients.
Test, analysis and benchmarking
Utilising state of the art facilities, including three flexible powertrain semi-anechoic test cells, Ricardo supports testing across road - including passenger and heavy duty vehicles - aerospace, marine and rolling stock.
Extensive capabilities
Ricardo provides NVH simulation capabilities including intake and exhaust, base engine, powertrain mounting, driveline, e-machine, pass-by, road noise and gear whine
Rail sector expertise
Within the rail sector, we provide clients with NVH support and analysis from early design through to investigations of emerging in-service issues.
We offer extensive support on reducing airborne and ground-borne noise and vibrations, including onsite measurements of current noise levels, noise-reduction programmes for vehicle fleets, and mitigation responses following reports of non-compliance.
Our deep understanding of international practices has also been used by clients looking to ensure products or entire systems comply with market expectations. Recent assignments have included helping an international rolling stock manufacturer comply with local noise regulations and producing research on high-speed rail noise reduction measures.
Services for rail clients include
- Verification of (legal/client) noise and vibration requirements.
- On-site measurement and monitoring.
- Specification of appropriate mitigation measures in the event of non-compliance or formal complaints.
- Noise reduction design advisory for rolling stock.
- Applied research into noise and vibration reduction measures.
