Acoustic assessment of the Acoustic Vehicle Alerting System (AVAS)

Electric and hybrid vehicles have many advantages. One of them is their contribution to the reduction of road traffic noise, which disturbs a considerable part of the population in Germany.

Due to the lack of a combustion engine, vehicles with electric drive can be driven almost noiselessly up to a speed of about 30km/h. When driving faster, the rolling noises of the vehicle tires usually dominate to such an extent that electric vehicles are as loud as vehicles with conventional combustion engine.
