Quiet Vehicle Sounder – Acoustic Vehicle Alerting System (AVAS)

Known as an acoustic vehicle alerting system across the automotive market, the Quiet Vehicle Sounder warns vulnerable road users of an approaching electric/hybrid vehicle.

The problem with silence

Without an acoustic vehicle alerting system, electric and hybrid vehicles are almost silent; they are only audible once they have built up some speed (approximately 20kph) when wind and road noise generate enough sound that they can be heard. Studies have concluded that electric and hybrid vehicles pose a danger to vulnerable road users (VRU) and increase the risk of incidents with pedestrians by up to 80%. Sound is an important contributor to road safety for pedestrians, not only for the blind or visually impaired.
