  • The extensive NVH test facilities at Ricardo enable accurate measurement of NVH 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.
