Active Road Noise Cancellation

[Hayseed_MS]

Interesting in that on the OEM 21's I had a consistently marked improvement.

I put the aftermarket 20" Pilot Sport A/S back on. It is now hit or miss. About 50% it is a marked improvement. 25% no notice. 25% worse echoing sound.

I turned it off yesterday on a steady highway cruise at 70 mph and heard a difference at very low frequencies

But if someone had turned it off without you noticing would you even have known?

The echo sound bug is an abomination, and they all do it at some point (I’ve tested on multiple cars). I guess like the vibration issue most people are just oblivious.

no. you have to really listen for a difference for sure.....

Yes. I have blind tested passengers and they could tell.

Bet you anything if you turned it off before they got in the car and didn’t draw attention to it they’d never notice. I sure as heck notice the echo thrum though!

No and yes.

Right. I get the feeling this feature was meant to be more baked, and then the team realized they couldn’t do much with it (thus the name change from ANC to ARNR) and it not ever being talked about by absolutely any publication or Tesla. I wouldn’t be surprised if Tesla removes it from future cars. It’s a waste of money and components.

 

[Hayseed_MS]

Surprised someone is not on here whining about the yoke causing the issues with ARNR...

My Active Noise went whacko over the weekend.

It happened just as the speed limit reduced which forced the car to slowdown in AutoPilot.

Horrible screeching sound. No idea what it was and thought I blew a motor or something. Pulled over and it stopped. No errors on the dash. Started to drive again and the noise started again.

Then I had a hunch it was noise cancelation. Turn it off and it stopped. Only thing I did.

Most owners know volumes of things are pretty messed up. Sometimes blinkers are loud, sometimes soft, sometimes normal. Nav level can jump around too.

What I think happened is the noise cancelation was suddenly excessively loud.

A Little later, turned it back on and it was fine.

That’s nuts. I’d leave it off. Not worth the hassle. In my experience it either does marginal-to-no-good or introduces noise. @jebinc

To update, I'm now on 2022.40.4.1. Figured it was worth trying Active Road Noise Reduction to see if Tesla has made any improvements.

NOPE!

Still an absolute abomination. Turned it on while going 60mph, - it calibrated over the next couple of minutes and then introduced MORE tire noise echo, easily reproducible by toggling it on and off. How does Tesla get away with this crap?

Because they can (until there is more competition). How do they get away with the years worth of BS on FSD? All of the software that has been in beta state for many years? Rhetorical.

Yep. It's really ridiculous...

I suspect ANC is not really possible in a vehicle. ANC works great with headphones or earbuds, where you can separate your hearing from the outside noise to reject. With vehicle ANC, over the entire frequency range, with multiple sound sources and various sound phases trying to reduce noise at multiple moving spots in the car (i.e. your ears) does not seem possible. Great idea, but not practical in my opinion. I give Tesla a couple of brownie points for trying, but as others have concluded, it's a dead feature and I wouldn't expect to see it ever really working.

While my esteemed colleagues @jebinc and @WilliamG would disagree, I have success with the ARNR more times than not. That is why I say it works but not consistently. I feel it is not ridiculous but not perfect either.

Had a chance for a nice drive with my new P Zero Winter in the OEM size 21". These are the T0 marked so they have the foam and EV designation. The tires took the road noise down considerably over the Pilot Sport All Seasons I was running. During the drive on side streets and interstate, it definitely made a difference toggling the switch. It subdued a few tones enough to be noticeable.

Keep in mind this is no longer thought of a ANC but ARNR so they have admitted their defeat to an ANC level of reduction.

Still a work in progress but leaps ahead of it when it first came out in the car. It has improved to the point that I leave it turned on 100% of the time.

I find that truly fascinating. I’ve tried ARNR on 3 or 4 new S and it’s awful in all of them. I can’t fathom it…

Would let you drive it but you are too far and you jinx every car you drive/ride.

Na. I just see what’s already there.

No kidding! I’m doing my best to keep him away from my PoS Plaid and new R1T!
