ECTunes has developed a new and innovative technology, which provides electric and hybrid vehicles with sound. And it is not just the sound of an engine, a song or other already seen features. The new technology is unique in the way that sound is composed and designed to obviate the need for variation. When the EV moves forward, the sound is only in front of the vehicle — as a warning to vulnerable road users that a vehicle is approaching and at the same time minimizing unnecessary noise on the sidewalk. The sound from the vehicle is depending on the direction, speed and acceleration of the vehicle.
