So I actually tried my sennheiser noise-canceling headphones and they actually made things worse because they can barely do anything to cancel out frequencies so low, but in fact cancel everything else out. So the net effect is that the booming rumble seems even louder and worse since it's the only remaining audible thing.

2021 Model Y lots of road noise rumble on stock 19's - any advice for improvement?

There are no silver bullets when it comes to reducing noise levels in cars. Luxury makers can use up to 500 lbs. of sound deadening materials. Think what that would do to an EV's range. Lead is the best material because it is really dense, but obviously impractical due to the weight. Tesla's cars often weigh less than competitors EV's and maybe part of the reason is that they accept more noise rather than more weight, thus less range.
This Extech SL510 is a perfectly good professional dB meter and accurate to within 1dB. It’s not the best thing ever; I’d love something with some more modern capability like a built in FFT readout and an easy way to get records into a computer. Unfortunately meters with those features are typically thousands of dollars. But for the price it’s quite good, with the main benefit being the accuracy and reliability of the readings.
Jeez this sounds horrible. I don’t have my Tesla yet but if it was like this I would consider selling it quickly.
Hi, I found this thread and was going to make an appointment with my service center to try to get them to fix the sub in the hatch to see. I also fixed the squeak from the amplifier in the back right trunk behind the panel. I also isolated the sound from under the second row by placing felt under the seat actuators which are hooked on the same way as the amplifier and screwed down metal to metal. I have a service appointment to fix the middle seat rattle that is probably from the middle seat actuator. Fixing the amplifier and the middle row left and right seat actuator has made a world of difference. I currently keep the middle seat folded down to prevent the middle seat from rattling. Next is trying to get them to work on the sub in the hatch where I think a lot of your sound is coming from as well

Fixed Trunk Rattle
tl;dr - The source of the rattle was missing padding and insulation on the paneling around the subwoofer. Background Since receiving the Pearl White Model Y PUP I’ve had numerous SC visits for door alignment, frunk closing, wheel alignment, trim discoloration, spoiler coming off, and a...

Thanks - I used an earthworks M3 with Izotope RX in my cars but have been unable to make sense of the data. I’d be happy to process any recordings in RX.
Ordered the Extech. Will see what happens.
I’m an audio engineer. I’d be happy to evaluate any recordings you have. The main thing to understand is that a recording will not allow me to evaluate loudness in the car itself (dB SPL, or sound pressure level, the real loudness in the world). That can only be determined using a dB meter and noting the readings. But I can do spectral analysis and identify which frequencies are loudest in relative terms.
You were very savvy to get an Earthworks mic for recording; these have an extremely flat fast and accurate frequency response making them well suited to frequency analysis.
I reached out to Mountain Pass Performance and Unplugged Performance to ask if their respective Comfort Coilovers would add any improvement to this booming road noise issue. TL;DR - nope.
Here is the response from MPP:
While they improve comfort, there isn't anything special about them that would reduce the transmission of road noise into the cabin. Our kits use the same isolating parts as the OEM suspension, which is something most aftermarket kits don't do. I think the cargo tray is your best bet, and you could even try a bunch of blankets first to test my theory!
And here is the response from Unplugged:
The luxury coilover kit will definitely help with the ride quality, especially over bumps. Since we are replacing the factory shock with a new unit along with an appropriate spring, the ride will be smoother. Our shock is adjustable so we can also dial in how firm or soft you want the ride to be.
As far as the noise coming through the car, the coilovers will not fix that issue. The issue is due to a lack of noise insulating materials and with the car being electric, outside noises can seem louder when compared to a standard combustion engine car.

I have a 2021 MY LR with standard wheels/tires and am very bothered by the boominess. I’m encouraged that you report that changing the tires made that sound just go away. But I don’t understand why more people don’t seem to acknowledge that you appear to have found the silver bullet. Do you know of anyone else who has changed tires with the same result? Do you have any doubt that the issue you were experiencing was the same as the OP and that the tires fixed it? I’d happily buy a set of these tires if they would fix the problem but I’d truly hate to spend $1000 and still have the same problem. Thus my request for double-confirmation. Thanks for posting your experience and for humoring me!
EDIT: In another thread, you said this about your new tires: “Any vibration/humming over 60 mph is now gone”. Is that the noise you’re talking about? Because the boomy noise I have is at low speeds.

I changed my tires with very low miles and the boominess is still there. So it didn’t work for me. It’s the stiff suspension.
That's not true with MPP. They eliminate the rubber padding on top and bottom of the springs in their assembly, so they have worse isolation than OEM. Surprised they would make such a false claim.
When searching for the quietest possible tire option I came across the Bridgestone Turanza QuietTrack. Anyone have thoughts on these?

So possibly the Vredestein ones do better. I guess I could spend the money and find out!
Consumer Reports rates the Bridgestone Turanza QuietTracks as a good bit quieter than the Veredesteins. Check them out and see what you think.
I’m not sure it necessarily has to do with which is the quietest… maybe it is more which one transmits road bumps to the chassis less. I think in the end it is still unclear what exactly causes the boominess.
