Our EV (a Hyundai Ioniq 5) emits an artifical sound, presumably to warn pedestrians, which I find interesting.
It's an attention grabbing electronic hum, swelling, but not overtly threatening. Sounds something like a well tuned very resonant transformer. It's also not too annoying to the car owner. I'd love to know the backstory of how these sounds are created and what sort of testing goes into it.
On the same note, the light saber noise from Star Wars was allegedly inspired by an idle video projector.
“Immediately something went off in my mind and I had a feeling for what they would sound like,” Burtt said. “In the booth where we projected the films, those projectors made a hum…the motors would sit there with this magical, mysterious humming sound… I thought ‘that’s probably what a lightsaber would sound like.’”

- mc32 4y agoMaybe they can use the Logan's run solar car sound as a stand in for engine noise. Or grippier tires too but then that gets loud on the highway. Maybe a certain frequency would be noticeable (rumble) at low speeds but ultrasonic at high speeds?

- randomhodler84 4y agoI find this tone irritating. It sounds like the first part of an air raid siren. Puts me on edge. No thank you Hyundai.
- otterley 4y agoIt’s intended to get pedestrians’ attention. Sounds like it achieved its goal!
- jacquesm 4y agoIt should activate the brakes, not emit sounds to cause others to have to respond.
- RedShift1 4y agoPeople are already getting lazy and crossing streets only looking when they have already started to cross or sometimes not at all. Emitting no sound at all sounds like a terrible idea.
- jacquesm 4y agoNot where I live, but then again, here we have lots of very quiet vehicles (bikes, e-bikes, s-pedelecs and e-scooters). In a city like Amsterdam such an alarm would be going off all the time adding significantly to the noise pollution, one of the advantages of electric cars is that they are quiet and this to some extent negates that. If you are worried enough about a pedestrian that you want to make a sound to alert them to your presence then between the emission of the sound, it traveling to the pedestrian and their reaction precious time is lost. That's why I think applying the brakes to the point where everybody is kept safe is a better strategy. It also takes care of the assumption that the pedestrian will respond to the sound, especially if such sounds are not standardized between brands (engines are all recognizable as engines).
