https://www.youtube.com/playlist?list=PLWxrK_3LlEr9WsfOL8N41... I absolutely love the reverse sound my Toyota RAV4 Prime (hybrid) makes: https://www.youtube.com/watch?v=gUT94MBt_Ao To me, it sounds like the future. Sort of a hovering UFO. People's heads definitely turn when I back out of my driveway.

Let me make sure I've got this right... According to the video, if the driver of a Toyota EV reverses through a "cross walk", and hits a pedestrian, it's the pedestrian's fault for not getting out of the way? And, in order to prove that it must be the pedestrian's fault for not noticing the vehicle reversing through said cross walk, the vehicle omits an obnoxious noise at high volume?

I didn't watch the video, but both practically and legally speaking, in the US when a car hits a pedestrian it's considered the car driver's fault, excepting some circumstances. The noise doesn't have anything to do with it- cars have to stop for pedestrians in marked crosswalks, and should stop at any formally defined crosswalk (not all "crosswalks" are directly labelled or signed as such).

God, the Hyundai sounds are terrible in Korea. They sound like a UFO and are very loud. They tried to go too hard with the future vibe and it drives me nuts living in the small streets of a very busy Seoul. Oh my god it actually sounds like a more high pitched version of the Jetsons https://www.youtube.com/watch?v=4NgSZ8sjDgU Edit: Found it, look how loud this shit is! https://www.youtube.com/watch?v=IgvUu2YZ5ps

Holy crap, is that modified or do they all sound that loud? And not just in reverse? Not the future we were promised.

They all sound like this (the newer models obviously, probably as far back as 2020)

I'm sure there's a way to hack it and turn it off... but who's going to do that?

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

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

I think you're the one missing something. I just searched that exact phrase and all the sources I can find says they play the sound through the interior sound system. Can you find me a source that says otherwise? I can't.

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.

That's incorrect. I just did some searching and they play the sounds through the interior sound system.

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

I'm aware of that. We're talking about artificial engine sounds, though.

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.

That sounds a bit theoretical in this context, I am sure auto makers would love to save the costs of external speakers, so the incentive is there to drop them if the sounds were not mandated.

This would be great to load up onto an RPi and put into a kids toy. Maybe use it to pimp up one of those toddler steering wheel sets.

Why turn your kid into a degenerate before they've even reached adolescence?

The car sounds add to the experience of playing with a steering wheel, versus some tinny soundbox?

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

Try living downtown in South Florida.

The first mistake was living in Florida

These are results from the first page. Not an endorsement.

From the descriptions it's unambiguous that these add-ons are not pumping 100dB into the car's interior.

I'm not a motorhead, so I only skimmed second hand part offerings and found this: OEM Maserati part number 670006946. For optics it's advertised as noise cancellation system, but owners' forum [0] suggests it can work either way. They also discuss a defeat mechanism.
