Unless I'm missing something, these sounds only occur inside the car. Can you explain how that affects you?

Oh but they don’t! Lots of German “performance” cars now have speakers under the car to make obnoxiously loud sounds. They can’t produce them naturally because the muffler regulations prohibit unfiltered exhausts - hence speakers. AMG, Audi RS, M Power - they all do it.

Do you have an AMG example? Afaik they only play engine sounds in the interior.

Reading a lot of the comments it seems that most people here are keen to have otherwise quiet cars fitted with fake sounds. While I appreciate there's a safety aspect to making some sort of sound for pedestrians, I am actually looking forward to a future that makes cities and heavy traffic areas both quieter and cleaner. If you live in such areas, this would be a great quality of life improvement and dare I say, may…

Having lived in apartments on many busy roads in my life the main source of noise from cars is tyre noise, not engine noise.

In ICE cars, some people remove the mufflers and modify the exhaust for louder and more deeper sounds.

I wonder if they could go the other way and use loudspeakers for external active noise cancellation.

wtf is external noice cancellation

I believe they refer to something similar to this: https://youtu.be/y2RAsubSDAk?si=anuRAPCCI9Z0NQMJ&t=144

Sorry, for the obnoxious video. I couldn't find another quick example.

Try living downtown in South Florida.

Yes! I've already written NHTSA and US DOT about getting these synthetic noises banned. The more people who do the same, the more likely it'll get noticed. Now, we just have to figure out how to include motorcycles...

>> getting these synthetic noises banned.

Not possible. Db limits are one thing, but a content-based rule would be akin to banning certain types of music.

Tangentially: Does anyone know where to find a collection of the low speed sounds emitted by electric vehicles (in the US at least)? I'd be interest to hear the different approach different manufacturers have taken.

i too would be very interested in this! i am for now a petrol head but continue to be fascinated and also mildly irked by the varying EV sounds. some sound like galactic spaceships, some like weapons, some like "blurred mechanical noise", and some are almost indescribable in words. some can be semi-nightmarish. i'd love to play with a soundboard that had all the different EV manuf sounds on it.

> semi-nightmarish

There's one I hear regularly that sounds like a choir of demons.

They already do have active noise cancelling, but I believe it is to benefit the passengers.

Yes, you are missing something. Query for your favorite search engine is "active sound exhaust system". This is how it affects me.

I love that when you get to max RPM in 6th gear and then just downshift to 1st you hit comically high RPMs!

More than you ever wanted to know about this. https://youtu.be/p9SbDvMhCFs And a decent specimen. https://youtu.be/EjHMkkkLQaU

The best/worst of those videos are the ones where you can actually HEAR a bunch of metal bits hit the ground right after the shift :)
