Known as an acoustic vehicle alerting system across the automotive market, the Quiet Vehicle Sounder warns vulnerable road users of an approaching electric or hybrid vehicle.
The Quiet Vehicle Sounder is designed to emit a blend of Brigade’s bbs-tek® White Sound® frequencies and tonal sounds. This mix of frequencies ensures the QVS is only ever heard in the danger zone, is instantly detectable and locatable.
Studies conclude slow moving electric and hybrid vehicles increase the risk of incidents with pedestrians by up to 80%.
Government Legislation in Effect
