Why do all EVs make the same quiet hovering sound when they drive ?
In: Engineering
People have gotten very used to listening out for the sound of a vehicle approaching. Although the motors of an EV do make noise, it’s not a lot of noise. For safety, external speakers play the hovering noise at low speeds so that there’s *something* for people to listen for, but isn’t an obnoxious back-up beep or horn. The futuristic hover-whoosh sound is just what manufacturers have settled on as something that sounds scifi and modern and appropriate for an electric vehicle.
