BRIGADE Electronics has launched Quiet Vehicle Sounder (QVS), a speaker system designed to reduce collisions between pedestrians and hybrid/electric vehicles.

Known as an AVAS (Acoustic Vehicle Alerting System), the QVS simulates an internal combustion engine’s sound characteristics by emitting a blend of bbs-tek White Sound frequencies and tonal sounds.

Most hybrid/electric vehicles are virtually silent under 20kph and are more likely to be involved in accidents with vulnerable road users, says Brigade.

The QVS changes pitch according to the speed of the vehicle, mimicking a combustion engine’s characteristics when accelerating and slowing down. It can be retrofitted to most commercial vehicles, working from a 12 or 24 volt power source.
