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.
