    Ear pain/Pressure help

    Yeah it wasn’t an easy decision to come to. I WANTED to love the car. In theory I DO love the Y, but in practice it just didn’t work out. It’s incredibly frustrating because it checks so many boxes I had for a vehicle (Although I want my dang ventilated seats!!) I spent quite a bit of time...

    Ear pain/Pressure help

    Well I’ve resolved this problem for myself by selling the car to Carvana. Amazingly they paid so much over list that even with sales tax and fees factored in, I only lost a few hundred bucks. Seemed like the wisest way to cut my losses and move on. Perhaps when the new 4860 battery cells with...

    Model Y road noise/rumble primary cause

    Thanks for this! It certainly does appear that the primary spikey resonance is more tamed in your "after" recording; it's still present, but no longer standing out above the rest. All other recordings I've seen/done from inside a Model Y have a very distinct low-frequency resonance clearly...

    Model Y road noise/rumble primary cause

    Would you be willing to post a video clip of driving at approx. 30MPH on less-than-perfect roads so I could do an FFT analysis on it? I’d love to see the results.

    Model Y road noise/rumble primary cause

    Musk sure seems to corroborate the OP’s sentiments in this interview with Sandy Monroe. Specifically the section discussing structural battery packs around the 22 minute mark. Musk Monroe interview He essentially admits the cars have poor torsional rigidity due to the battery packs and that...

    Ear pain/Pressure help

    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. 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...

    Ear pain/Pressure help

    Is there anyone who has solved the booming problem who would be willing to post a YouTube clip here from inside the cabin while driving roughly 30 miles an hour on a somewhat bumpy road? I’d love to evaluate the audio and see what kind of results people have gotten. iPhone or android video...

    Ear pain/Pressure help

    Here's the FFT analysis of your recording. Looks very similar to mine, with the resonant peak at around 34.5Hz

    Ear pain/Pressure help

    So the service center installed the rear hatch bumpers and extra trim on mine. It reduced LCpeak decibel readings by about 3dB but average level by only 0.5dB. So I did some before-and-after recordings while driving on slightly bumpy roads at 30MPH and looked at the FFT. Here is before...

    Model Y road noise/rumble primary cause

    Thank you very much for this. Given the fact that this issue seems to plague similarly designed EVs (Audi E-Tron, Mercedes EQC, Mustang Mach-E to lesser extent) this is clearly as yet an unresolved problem with modern EV SUV design. Ultimately very frustrating but also very enlightening. I...

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

    Consumer Reports rates the Bridgestone Turanza QuietTracks as a good bit quieter than the Veredesteins. Check them out and see what you think.

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

    When searching for the quietest possible tire option I came across the Bridgestone Turanza QuietTrack. Anyone have thoughts on these...

    Ear pain/Pressure help

    Alright time to get super-nerdy. I came across this Swiss study from 2017 about how to deal with low-frequency resonances in passenger cars. The effectiveness of the suppression of low frequency acoustic resonances with porous sound absorbing structures of multifunctional upholstery...

    Ear pain/Pressure help

    Alright everybody, time for fun with automated translations! yesman686 posted two links to videos on Weibo, in Chinese, discussing the issue. Well I played a bit on the internet and managed to create some truly horrific translations from the Chinese audio into English text. See if you can...

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

    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...
