Right now, it isn't a 10k hit. I got an offer from zoom 1k more than I paid for the car (before taxes and fees). I'm waiting because I want to trade it in and here in Florida, taxes are based on the price difference.Have been following this thread for a little while now. If only Tesla still had their 7-day return policy still in place. I am an existing model 3 owner who bought Model Y with out test driving with the assumption that there is a 7-day return policy. I got it delivered to my home so some rep dropped it off in my drive way and left. The car unlocks only after you accept the delivery. The very moment I got in an drove the vehicle I realized I am going to hate the noise. I have complained immediately and even took the car to service center within 100mi as suggested by the sales rep when I called in to complain about the noise. Long story short. No return. Service center thinks this Model Y is as it should be.
If it weren't COVID times or if I had waited till I could test drive it properly before ordering or if Tesla trusted their products well enough to keep the 7-day return window for those who did not test drive.... Though I feel it's totally my mistake to buy a car without test driving it, Tesla's silent changes to policies every other day doesn't help. At the end of the day this is probably the last Tesla I am going to get.
Now that I am done with my long rant... I am figuring out how to live the car for now (not quite ready to take a 10k hit less than a month after getting the car). Did anyone with a 7-seat Model Y try padding the quarter panels with butyl? Is the removal process any different than the 5-seater?
That's interesting and the opposite of what I experience, which is that the pressure increases with speed. Around town I don't feel it at all. But on highways, once I get above say 60 I feel it. I did adjust the hatch bumper stops, and it actually helped a noticeable amount. Not completely, but I can live with it. Still, glad I leased so I have a firm end date for this.I think my hatch needs a slight adjustment. I took delivery yesterday and when driving home on Atlanta's city streets, it gave me the ear pressure and a bit of a headache. Today I drove it to the PPF shop which was a long highway drive. No issues on the highway because it is a smoother drive.
Hey sorry for the delay checking these out, I'm out of town at the moment. Just got a chance to fire up my portable rig and take a peek.Been meaning to do this and finally got around to it today. Car is modified as in my old post. I wouldn't say I solved the problem but rather reduced the volume of the sound by a considerable amount.
I held my iPhone 11 Pro in my right hand in the general area of the Tesla touchscreen and made one long video recording going down three different roads, first one ~30 mph, second ~35 mph (starting at 2:00), third ~45 mph (6:00). All concrete. Then I demuxed the audio from the video losslessly and linked it below.
In the middle of my trip down the second road, starting at 3:00 and continuing for the next minute or so, there are a couple booms as I go over particularly challenging stretches of pavement. As others have noted, specific textures in the road surface really seem to bring out the sound. I suspect it's not how "rough" the surface is but rather stuff above my education level involving resonance. In any case, what I'm trying to say is that different sections of the recording may have very different spectra. I would love to see a chart of the change over the length of the recording but I don't have the experience to produce such a diagram or the time to learn how.
Even though I am leasing mine, I am getting this installed:Has anyone tried the cargo bay cover trick to reduce the space inside the trunk?
What about filling the trunk with acoustic foam or a carpet remnant just to see if it makes a difference.
The mountainpass coilover just minimizes the jar which reduces the boom but probably doesn't fix the root cause.
From what I've read so far, it sounds more like we're inside a large subwoofer.

Where on the car will you install it and who is installing it?
I have already reduced the tire pressure to ~39 (i did read the whole thread) and adjusted the hatch a bit (still needs another look). The sound improved from outright painful to just annoying.Consider dropping your tire pressure to 38 and adjust the hatch bumpers first. They may solve most of your issue.
Thanks for these results. They match up with my subjective experience pretty well. The primary benefit I got from adding insulation was not to totally shift out of the low range but rather to dampen overall (decrease perceived amplitude). Unfortunately I think most digital recording equipment today including phones have automatic gain control that you can't disable. And I don't have a recording from before I added the insulation anyway.Hey sorry for the delay checking these out, I'm out of town at the moment.

So interestingly it seems you've shifted the peak from around 35Hz to around 46Hz, but it's very much still got a loud peak at that low frequency:

At another time point in your recording it looks like this:
View attachment 669526
So the peak is very distinct at that somewhat higher frequency.
During the calmer section of your recording the more typical 36Hz is again the dominant frequency:

So the take-away seems to be that it's possible to shift the energy build-up to a somewhat higher frequency, but it's still present.
Do not do this, I did it and spent hundreds and it’s not worth it. I applied the butyl (both same products you linked) with a roller and with the foam on top in the rear quarter panels, removed the trunk carpet and box, lined it all and even the trunk cover I hot glued it. Put thick memory foam pillows in the rear wheel wells, no noticeable difference. Save your money and consider another ev if you can. While I hate Audi I test drove an etron and what a world of a difference.Even though I am leasing mine, I am getting this installed:

HI all,
i just picked up my model Y after PPF wrapping. the guy help me pull out the interior from the trunk area without success. my model Y is 7 seats which is a new case which people never se before.
it might need to take off the 3-row seats to take off the side panel on both side. The guys feel not comfortable to take off the seats since there is marks on the screw and it might void the warranty. My Y was picked up on March 2021. I have scheduled the tesla service to see can they able to take off the 3-row to let me install the deadening matt.
As you will see the 3-row seats is blocking to side panel. Any idea what should i do next? maybe just put the deadening matt on the Black under trunk box
Here are some picture.
