Brigade Electronics launch Quiet Vehicle Sounder for Electric Vehicles

On March 18th 2019, Brigade Electronics launched the award-winning 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) across the automotive market, the Quiet Vehicle Sounder simulates an internal combustion engines 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 (VRU) who do not hear the vehicle approaching. Reports estimate that the odds of a hybrid/electric passenger vehicle being in a pedestrian crash are 22% greater than an internal combustion engine passenger vehicle[1].


The Quiet Vehicle Sounder changes pitch according to the speed of the vehicle, mimicking a combustion engine’s characteristics when accelerating and slowing down – a sound that is easily identified as a vehicle by a vulnerable road user.


“We are delighted to bring an award-winning solution to a growing market that will alleviate the dangers posed by quiet vehicles. Sound is an important contributor to safety on the roads, yet electric and hybrid vehicles are silent.” – Philip Hanson-Abbott, Managing Director.


The Quiet Vehicle Sounder is available worldwide and can be retrofitted to most commercial vehicles. Working from a 12 or 24 volt power source, the QVS will not drain a hybrid/electric vehicles power.

Quiet Vehicle Sounder Features and Benefits

  • Multi-Frequency bbs-tek® technology means the sound is only heard in the danger zone
  • Pitched shift tonal sound: similar characteristics of a combustion engine
  • CAM Switch and Tacograph Compatible
  • Designed in accordance with regulations UNECE R138 and NHTSA 49 CFR Part 571 and 585
  • IP68K speaker
  • 12/24 Voltage Power

Key Stats

  • 40%: How much more likely pedestrians were to be hit by a hybrid or electric car than a car with a combustion engine, according to a recent study by the UK-based Guide Dogs for the Blind Association[2]
  • 74%: That’s how much closer a group of subjects in a University of California, Riverside study needed to be to hear an electric car over a combustion engine. Those seconds could mean the difference between an accident or moving out of the way unscathed[3]
