I think a good artificial noise for electric cars to generate, so they are audible enough for pedestrians and others to be aware of them nearby, would be the synths from Darude's Sandstorm.
the beauty is how this gets proportionately better as more EVs are on the road and using it.
@jackdaw_ruiz singular tone or all doing it speed dependant
@IntrepidVector @jackdaw_ruiz a chevy bolt screamin by at 90 mph playing Sandstorm at 2.5x speed
@coriander @jackdaw_ruiz see that's just a safety feature

@IntrepidVector @coriander @jackdaw_ruiz I think above some speed it needs to switch to another song...

Deja Vu, I've just been in this place before
Higher on the street, and I know it's my time to go
Calling you, and the search is a mystery
Standing on my feet, it's so hard when I try to be me

@jackdaw_ruiz In all seriousness though, have you ever been in a parking lot or slow traffic when a car is approaching you from behind? What do you hear? It's not engine noise, even if it's a gas-powered vehicle, unless it's got straight pipes or they're revving their engine to deliberately make obnoxious noise. What you hear is tire noise, and at slightly higher speeds wind noise.

All the nonsense about "I got hit by an electric car because I couldn't hear it" is oil company propaganda.

@callisto

mmm electric cars are seriously like 1/10th the noise (obvs depending on variables at any moment like if it's accelerating or idling, etc...) and the difference ends up being are they loud enough to be noticeable above other ambient sound, or not?

like. I am posting this from a parking lot in Portland right now. EVs gliding past me as I type. the petro industry is godawful but asking someone to disregard their own sensory input and chalk it up to conspiracy is a fridge too far.

@jackdaw_ruiz OK, I'll concede your hearing is a lot more sensitive than mine (and I've been tested recently, my hearing is average or better for someone in their 60s). As a runner, I've MANY times had a standard gas powered car follow me politely on a narrow small town street, and I had no idea they were even there until they beeped. If I hear anything, it's always the tires.
@jackdaw_ruiz @callisto now, I don’t drive and I don’t know car breeds *at all*, but any time I’m walking and I hear a weird whirring or swishing noise or whatever I know there’s an electric car near. The volume is not linearly proportional to speed, it starts off loud enough that you can hear it even at a crawl, at least assuming your hearing is ok. ā€œDisregard[ing] their own sensory inputā€ is not the same thing as ā€œlacking situational awareness.ā€
@jackdaw_ruiz @callisto I like how EVs don’t sound like anything else. You know what it is, because nothing else sounds like that.
@jackdaw_ruiz instead of the current Tesla backup noise that sounds like a robot approaching climax?

@jackdaw_ruiz
Maybe a selection of tracks, like your cellphone...

Except for Tesla's, which are hard coded for Julius Fucik - Entry of the Gladiators

@jackdaw_ruiz I'm going to get an EV that plays "Hamburger Lady" by Throbbing Gristle.
@jackdaw_ruiz @mattgrayyes If it was a standard, I'd agree - issue with it at the moment is from a visual impairment issue: each maker chooses their own noise, so unless you know "this is X's noise for a car", it doesn't sound like a car. The one thing ICE vehicles all do is sound roughly the same. *nods*
@jackdaw_ruiz what about a continuous farting sound that gets louder and more violent with speed
@jackdaw_ruiz I wonder if rather than making electric cars noisier we should have regulations on vehicles that are too noisy?
@Workshopshed @jackdaw_ruiz We most definitely should, since noise pollution is no small issue, affecting the collective environment and individual health: https://electrek.co/2023/03/20/we-require-noisy-evs-for-safety-but-lets-stop-the-real-killers-suvs-gas/
We require noisy EVs for safety, but let’s stop the real killers: SUVs & gas

Noisy, gas-guzzling trucks & SUVs kill pedestrians (and everyone else) at vastly higher rates than EVs. Why do they get a free pass?

Personally, I feel the only acceptable artificial noise for a car to produce is this:
