How effective is active noise cancelling in a car?
- Thread starter jboy210

One of Tesla's partners has a concept or patent for noise cancellation. I think that coupled with double-paned windows and better insulation, noise cancellation would fix one of my biggest complaints with the Model X: wind and road noise.

Know I'm rather new to my 2021 Tesla XLR+, but outside noise is SO minimal to ANYTHING I've driven in or ridden I can't really understand need for more noise cancellation.

Very well! Most of the extraneous noise in a car is fairly constant; wind noise and the sound of the tires on the road are exactly the kinds of noise a noise canceling system is perfect at reducing or eliminating.
I bet if you went through my post history you'd find posts harping about how they don't have it. I experienced it in a 2005 Acura RL, and it was amazing, so comfortable and easy to hold a conversation, night and day compared to my vehicle at the time, which at least felt quieter than my X ever has.
It really depends on Tesla's implementation. Ventilated seats in general are awesome. Tesla's initial attempt at it in the X was awful. As with all features, the technology and manner in which it is used will determine whether it's meaningful.
I have never had any real road noise or other issues in my X. It's the quietest car I've ever driven.

Wow you got lucky. I went from a 4 series BMW with extra hard run flats to a 17 X. The X was a lot louder, squeaked and creaked inside with every bump and turn and that wasn’t even the 22”. You should have seen my family’s face when we drove it after delivery. Loved it other than that though. Nervous and excited to see what we drive off in in April.

Are you referring to headphones? I wasn’t aware that aircraft cabins have ambient noise cancellation.

Battery cells != scalable
There are several different systems for aircraft, mostly OEM some aftermarket. I bought one for a King Air that totally transformed it! Suddenly the charter customers more than doubled and my spouse was thrilled. I actually flew without a noice-cancelling headset, having never done that before.
Well done the systems are amazing, and even th mediocre ones now installed in some cars are very effective, as people report in this thread.

Hurray for Canadian aircraft. Been in a few for short flights, only complaint, size. They, crew probably, killed my Chinese Prada overnight
the Saab 340 and Saab 2000 were the first ones, I think..
I really hope they can retrofit noise cancellation tech into older Xs ?
It's doubtful that older cars could be upgraded as it would require additional sensors, microphones, speakers and possibly a new MCU.
Here's an example of how Bose QuietComfort Road Noise Control works. I assume Tesla's noise cancellation will work similarly.
These all work similarly. The three I know of are Silentium (a JLR supplier), Bose (already mentioned here, famous for cleverness, sometimes not so much for component quality) and Samsung (branded as Harman). All of these seem to work well, but Bose tends to want to package together with the Bose sound systems, while the other two are less rigid. Clearly integration with the sound system makes the entire project far more efficient.
Since Tesla describes fairly exotic sound system for the new S and X ti seems that is how they planned it. Tesla's apparent chosen partner is a Bose partner so... but somehow I imagine Tesla would not be overly excited about the Bose heavy handed approach.
This is a rapidly evolving field so we must wait to know. In the meantime there will be retrofits possible soon for an aftermarket supplier. That will be expensive and require some significant installation. I went through that for an airplane. It was obscenely expensive but worth it.
We have a 2014 Cadillac ELR plug-in hybrid with Bose active noise cancelling. It seems to work pretty well, although there is no way to toggle it on and off, so direct comparisons aren't really possible. Overall, the car is exceptionally quiet compared to our Model 3. If Tesla didn't think it was worthwhile, I doubt they'd be paying to license the technology from Bose.
That said, the Model 3's audio system sounds better at moderate and high volume than the Bose system in the Cadillac, but the Bose sounds better at low volumes due to their aggressive loudness.
