Coming from an acoustics background, this kind of job is really difficult. In order to remove half of the perceived noise, you have to remove almost 90 % of the actualy acoustic energy (This is a consequence of the human hearing being logarithmic). The butyl panels are only partially for stopping sound from transmitting, but are mostly for making panels and surfaces not resonate and in effect amplify sounds. And I think very few surfaces in the Model Y are resonating meaningfully. As a Model Y owner myself (2022 from Giga Berlin), I believe most of the noise is due to stiff suspension, and the road surface roughness is simply transmitted directly through the tires, wheels and suspension to the frame. A suspension setup with more compliance at higher frequencies would likely do wonders for cabin noise. Recently, on my commute route, there was new, extremely smooth asphalt put down, and even at 110 km/h (70 mph), the cabin is really quiet. But thanks for sharing this. This is really valuable to the community.
I had the same experience with my Model S this week - when I got to the newly-laid asphalt, all noise disappeared. It was so unexpected and noticeable, that it made a strong impression on me and came to mind immediately when I read your comment. That being the case, tires will have a major impact on sound dampening. Tesla specified 45 psi for my tires, but I keep them at 35-38 and that seems to really dampen the sound a bit.
What you did was absolutely great. I am sorry it idd not help you and costed some money, however you helped many many morons like me, who would have gone in to great lengths to do the same. You absolutely saved thousands of hours of our time covering everything. We are on the same boat as you are, and after seeing your work, I have absolutely no need to strip anything. Everyone watching this, knows that you did above and beyond. Thanks again.
I have successfully dampened other cars in my past (Subaru, Mitsubishi, ...) and knew a pro who did this for a living. In those cases - great results. Also from a audiophile point of view (sealed the door hulls, built in subwoofer integrated to the car in glass fibre). I have contemplated the upgrade you did more than once, but always suspected, that the aluminum plates were more silent than the steel of my other cars to begin with, ans as others have stated, I have experienced massive sound level drops on new "acoustic" asphalt they use here around densely populated areas. You are confirming that the nois is actually mainly from the way the wheels are coupled through arms and suspension to the chassis, where no amount of dampening would be able to help. So thank you 🙏for putting in so much work and documenting it too. I put my own project on this to a final rest - I will spend the time on researching for the most silent tires in stead. ☺
Mad respect to you Willz!!! I always try and keep my content realistic. I hate people that just say "Wow its amazing" when in reality there's no change. Sucks that you wasted the money but uploading this just saved me and MANY others the hassle of wasting time and money on this.
The low frequency noise transmitted from the suspension bolted to the body is the reason for majority of road noise in unibody cars. This changes as you drive over different surfaces. If the suspension is softer, half the battle is won, if not, no matter how much sound deadening you put in, it will only help with some frequencies.
You should do the doors + front wheel arches. That should make a difference. I've done this for an old hatchback once and it made a noticeable difference.
I applaud your effort. Awesome video and editing. And admirable work going that far in pulling up all the carpet and removing all those panels. I could see and hear your sadness at the end. I know that feeling of going in expecting something and putting in all that time and effort and ultimately getting no results. But I appreciate your honesty when you could easily lie and say there was an improvement to get people to go buy a product through an affiliate link. A few thoughts: 1. Those phone app decibel meters are notoriously unreliable - at least in absolute terms - due to the limitations of the hardware, though I'd like to think it would still show a relative change if there was one. Granted, your subjective experience via your ears is the important thing at the end of the day. 2. With some hand waving, butyl rubber is more for vibration and foam is more for actual sound, which is why you'll see recommendations to layer those. Mineral wool and open cell foam like an old eggcrate mattress pad are likely superior for absorbing sound, though not ideal for an automotive application. 3. Tire choice is going to play a huge role here in perceived road noise. EV-specific tires often include foam inside them now to reduce noise. 4. I think Tesla did indeed beef up some seals and deadening to make the 2024's quieter, and they added the double paned glass for the front windows, but at the end of the day we're fighting an uphill battle with that huge glass roof that sound waves just bounce off of instead of having any sort of headliner to absorb them. :/ I just got a 2024 Model Y and I plan to experiment by attacking the exterior wheel well liners and and undercarriage splash shields, but I'm going in not expecting much.
Good comment, totally agree! Just wanted to point out that there are plenty of after market solutions that cover the ceiling, starting from around a hundred bucks.
Well we've heard from several people that doing the doors and wheel wells is where you will see the best results. We are probably gonna try it to see if we can get the Tesla more quiet.
Have you thought about a sunroof shade? I wonder if some of the 71 db is just wind noise over the roof? Do like that you were straight up about the results, I was also considering soundskins but now I’m more likely to try a roof shade instead
I lined my rear arches with 3 layers of butyl then 1 layer foam. Made a noticeable difference. One layer of sound skins butyl was never going to be enough to suppress the road noise. Thanks very much for the video,very informative.
@@willzbillzfam Yeah, realistically on the Y the arches are wheel arches are really the only place where a noticable difference will be seen on noise reduction. You are also mostly getting the deadening benefit from the buytl and layer of foam on the SoundSkins Pro. You may want to try adding some closed cell foam on top the of that to reduce sound.
Next time try some new tires like the hancook ion evo a/s. That's my plan. also replacing the suspension. Most of the noise is road noise (followed by wind). I'm surprised the seal didn't work
Replacing my model 3 suspension with highland as well. Give the highland a test drive; incredibly improved. Motortrend article covers all the changes very well. Starting with struts but might do knuckles as well
First let me say that was very ambitious of both of you taking that interior apart. It’s a shame after all of that work the results weren’t better. I installed the weather stripping on my Model 3 and what I noticed was that it made less noise when closing the doors but I still hear the road noise. I think the tires are the culprit but unless someone does a comparison of different tires that’s yet to be determined.
I did like the same stuff on my Honda. I realize that the sound deadening is meant to reduce vibration of the metal, but not blocking sound wave. So for road noise, it just won't help. I think that some type of sound isolation cushion would do that job
you only used Butyl, you had to use layers of specific materials for that. Butyl rubber, Closed cell pe foam, then maybe MLV. mainly closed cell pe foam is what well decouple the noise and then MLV will be blocking the noise.
I was about to do this same brilliant idea I had to my MYLR lol. So I had a new thought about wheel/tire areas that I have not fully looked at yet but what about spray foam in certain gaps and in the wheel liner areas as it seems to me that is where most of the noise originates from. Foam reduces the noise the best and I noticed my previous Lexus truck was exactly that, foam inserts in a lot of the paneling gaps and wheel and fender areas once I opened them up. Nothing we can do about more acoustic glass but my Lexus was extremely quiet. Figured they must know a little something with all that foam and noticeable extra carpeting and padding. Just thought I might throw that your way since you are now a pro at removing everything in the Tesla. Thanks you saved me a lot of time and money because I was about to do the same matting idea next month thinking it would be so great.
I did sound deadening on fender wheel well + A, B, C pillar + kick pad trim. I can feel the difference how quiet it's in highway speed. 1. Fender Wheel well: I used anti vibration pad + thinsulate on fender metal + wheel well cover. But, it didn't bring much difference. 2. I worked on A B C pillar + kick pad trim filling with thinsulate. This made a huge difference and I can notice the difference right away without the decibel testing. It seems like you haven't done interior trim sound deadning job and you will see the difference.
I've been reading a lot and it seems that people recommend doing the rear wheel wells with multiple layers, 1st is butyl > next is closed cell foam > and last is massive loaded vinyl, each will have different roles, anti vibrations, absorbing noise etc. I'm waiting to do that with my rear wheel wells but not sure how many layers I can do with the side that has the speaker, wondering if I put too much there the speaker will not fit.
@@willzbillzfam Yep doing that today, will let you know. Also the 5/16” OD vinyl tubing around trunk seal trick works for me, obviously reduce cabin pressure & some back noise. If you haven’t done that I highly recommend, 10 mins trick literally.
Question, did you also adjust the rear hatch stops to try and reduce low frequency vibrations as it acts like a drum. Also, if/when you are ready for new tires, it'd be great to just see the difference a different brand makes.
Thank you! We think it's mostly from the doors, wheel wells, and all the windows. Nothing we can do about the windows but we might try to do the doors and wheel wells.
Thanks for the honest video Willz Billz Fam. Making a big difference would be hard since you already have the smaller wheels, so it would take switching to Koni FSD dampers and insulating the front wheel wells along with the doors in order to make a real difference. If you have Pirellis then changing to a quieter and softer tire once you go through these ones will also be noticeable when it comes to the low frequency rumble. As for reducing high frequencies, apart from also insulating the doors... the Y has a huge glass roof which reflects most of the sound, absorbs basically none and also transmits some of it from the outside. What can be done is getting a roof sun shade and then putting some acoustic foam between that and the roof, its thickness of course depending on how much room is there. There is acoustic foam with adhesive backing available, so it wouldn't just fall down. Only putting the foam up there would be aesthetically unpleasing, that's why I'm suggesting covering it with a Y roof shade which are widely available anyways. Best of luck with your projects 👍
I test drove a MYP a week ago. I dont understand this sound noise issue i keep hearing about. It wasn't an issue in the slightest. I had radio off as well.
Thank you so much for this video! I was planning to have this done for almost a thousand bucks at a shop, but I will definitely save the money for something else. Such a shame it didn't pay off for you, but you helped thousands of people avoid the same mistake 🙏 I actually have a 21 Model 3 and it's a well known fact that the 24 M3 Highland is much much quieter. People have installed the new Highland dampers to their older models and noticed a reduction in noise, along with a much smoother ride. So I believe a suspension upgrade might do wonders. Maybe you can get the dampers from the next Y version once it's released. I've heard some rumours that the new dampers use the same tech as Koni suspension, so you might also go for that even though it's more work and more expensive.
Glad we could help! Definitely expected better results but either way, we did the video to give an honest review and find a lot of enjoyment in that. We have been researching other products and came across ResoNix. The products are very expensive but the website explains a lot about the science and what it takes to actually get results (multiple layers to reduce sound resonance, absorb sound waves, and block sound waves). If we ever win the lottery, we might try it out.
I did the same on my 22 MYLR, the best result was when I put sound mats inside the fron quarter panels. Its very tough to get as deep as you want to get in there, but it actually made a much better response. I have not done anything to the door panels yet, but I have been told that will make a noticeable difference. Overall, not as dramatic as I had hoped, but I got a very noticeable improvement overall. I used cheaper mats also, and maybe spent about $125 all in.
@chrisshinkle7224 I also applied sound skins package. There is small difference for rear passengers but not for front passengers. How to remove front quarter panels? do you have video link? I am thinking of applying sound deadening under the foot area of front passengers. This area is close to front door wells and may give better results. What are your thoughts? Thanks for sharing your experience.
As an owner, a very happy owner of a Tesla Model Y, I can only share that when I replaced the stock dampers with Koni Special Active, the road noise got NOTICEABLY lower! That actually came as an unexpected bonus, for I was aiming to improve the drive quality. I was looking for improved stability and reduced harshness. The Konis did excellent job! I wish I had the possibility to compare them with other aftermarket dampers, but there was no suck option, that is why I went directly to Koni. In my opinion, this is the first upgrade every Tesla owner should do! The effect on the Model 3 was even more pronounced.
What year Model 3 did you add the Konis to? I have a 2021 model three that I’m planning to drive 10,000 miles next spring and would really love to lower the road noise.
@@ted_jerome it would help on all models up to 2024 Highland when Tesla switched to dampers of this type. Along with that, using the smallest possible wheel size with a soft and quiet tire also helps. After that comes additionally insulating the front wheel wells. And if you're nitpicky and also like better speaker quality, insulating the doors will add something also.
Great way to void your warranty lol. Main issue with the noise in the Tesla that is overlooked and my least favorite design element of the car is the ALL GLASS roof. It lets in a lot of sound while also reflecting a lot of sound that is already in the car. Compare that to a padded ceiling in a normal car and you can see why the acoustics in the Tesla suck. Take those sticky pads and just cover the glass ceiling in the car. I bet it will make a much bigger difference in the sound.
I notice that only 2/3 of the rear wheel well has sound skin, and the other 1/3 remains with the cheap factory insulation (at 7 min 39 sec). Also, on the part of the wheel well that has sound skin, the original factory insulation was not put back on top of the sound skin. Do you think putting sound deadener on that 1/3 of the wheel well, and putting back the cheap factory insulation in all cases, would have made a difference? Would it fit or it would end up being too thick?
I spreyed about 18 boxes of silicone paint for noise deadening all under it, the plastic covers also the four wheel wells but almost nothing changed, i did there for my amarok and also ford custom it was working great but not for tesla model y for this time
Hi I know what you did wrong. There’s a sound guy over here in the UK who sells similar sound deadening products for cars. He’s done a bunch of Tesla’s with great results. It’s the doors. You didn’t do the doors. He ONLY does the doors and sometimes the wheel arches but on the outside (by removing the wheels and arch linings). Try that in another video. Guaranteed to work. Just be careful with the rear doors as there’s a lot in the way. He doesn’t move everything as it’s impossible and no need. Go for it!
A lot of your road noises coming from the front wheelWells so if you’re not soundproofing the firewall, you’re still getting noise coming in there and then also the mass load vinyl works great but it’s a thick vinyl blanket that lays over your floorboard under the carpet that’s going to help a lot from the Floor, though you still have glass that’s single pain. And then, if you don’t have any sound deadening on your roof, and I believe that once the sound gets up and starts, bouncing off the glass in the car, it’s going to be hard to deaden it unless you put some kind of window shade on the inside to help dampen the sound.
That's just on the refresh Model 3 right now. The dampers will fit my 2022 Model 3. I ordered a set at the service center and will have to get a 3rd party shop to install them.
I bought the sound skins kit a while ago. I got most of the trunk trim out but then decided to abort because it took forever for me to figure out how to unclip various small electrical cables 🤣🤣. I also found a place to do the install but I didn’t want to risk adding new interior noises due to improperly replacing the trim pieces. I also messed up one trim piece near the rear passenger seat that I need to fix. Thanks for your review. I suspect the. 2025 model y will be a lot quieter just like the 2024 model 3 , it was like being in a crypt.
@@willzbillzfam It wont mean much but I did subscribe after watching JUST for the effort and your confidence to pull this DIY off. Impressive. The reason these static noise dampeners dont work is because they tend to only dampen certain frequencies. Meanwhile that frequency may not match or vary from road conditions, to car condition, to tire condition. Hence for the same reason there is active noise cancellation in most advanced acoustic devices whether it is headphones or a Maybach.
perhaps try quiet ride tires? ...i have a 2021 toyota corolla hybrid that is just killing me on road noise. in order to save gas they cut down on car weight - probably the same with Tesla. Try teaching your kids the art of Zen car door shutting...... :)
Greatly appreciate your efforts to make a good record of your best effort to sound-deaden your MY! Sorry you weren’t able to hear a big improvement. After reading the comments, I think I’ll go after my front doors and wheel arches for my ‘21 M3SR+.
Thanks for sharing your experience here, much appreciated. Nah I wouldn’t go down that track, why? Because I have driven many cars and they each have their quirks. Road noise is a fact of life when driving anything. I have a lot of fun on a noisy tractor actually.😂
Read about a guy here in Norway that insulated the doors properly when they changed the whole speaker system to Focals. They had to remove the windows to put the insulation on both sides. But it supposedly made a huge difference.
Ive heard the front wheel kits are the most effective for road noise! They make them for Model 3 and Y and cost about 150$. Could be worth looking into!
I think the sound deadening we got did help BUT we just need to do it on the doors and wheel wells to really hear a difference. I think it would help your door issue
Had my 2024 model y for 2 months. So far we think ours is pretty quiet riding. Depending on the roads we are driving on. That was alot to go through for no glory. My BMW 530i was much more quiet riding but much more $$ also dont miss putting in premium gas . Little more noise but definitely not terrible. Great and impressive try . Thanks for being honest.
Yah definitely a quieter ride right out the gate. I imagine they'll keep getting better and better with sound deadening. We don't miss gassing up either!
You put product everywhere it didn’t need to go. Floor is pointless because you already have a massive battery there. Doors, all of them (and yes your sound will improve). Wheel wells Trunk door. Frunk bin (backside) You also need a layer of MLV or fiber sound absorber ON TOP of your first layer of sound dampening (the same stuff you guys used in this video). Tint your windows, use ceramic coating and tint your windshield too. Helps a bit with resonance and sound also. My Tesla is dead quiet.
Great experiment though! Think most of noise comes from windshield, fenders & tires. That noise reverberates w a glass roof too - sun shade may actually dampen more than insulation does. Thanks again
You didn't do the doors or the rear door, that's where the sound is coming from. Just tap on the panels and hear how tinny it sounds. I did a similar thing with ICE hyundai i30 wagon but only doors, trunk floor, so everywhere where carpet didn't have to be removed. I bought new floor mats, higher gsm than standard mats and got good results. You also didn't hold the phone in same spot and you did door close test from the back. Post installation was different No point doing tesla floor as you have batteries underneath no sound will penetrate through that from the outside.
"Loyal watcher and commentator" What was the preparation to get the leg stance on the car like that!!! Apperciate any recommended stretches or clothing ideas.
Good points. We have since found out that the doors are also one of the main ways noise gets in so by not treating those, we missed out on actual benefits.
Thanks for sharing. I was hoping with all the material you guys put in, you will achieve Rolls Royce level of quiteness.. But that was disappointing. Maybe the material chosen is simply inadequate for sound proofing. I personally was thinking if I ever carry out soundproofing ill be choosing mineral wool sound proofing.. the stuff they use in residential buildings. But then, there probably is risk of fire..
The other risk which we just found out about the other day is not putting everything back together correctly. We were pretty careful taking everything out and putting it back in but still managed to route the wiring for the driver seat incorrectly and ended up damaging the wiring. We had to pay $700 to get it fixed.
The main noise comes from the wheels, so the first thing you should always do is apply soundproofing material to the wheel arches. Additionally, you should remove the door panels and soundproof the doors, not the trunk.
@@willzbillzfam seen someone use MLV but its hard to work around with. I suggest butyl rubber and then closed cell pe foam. ua-cam.com/video/NZlqfzl5fus/v-deo.html
It sucks that you have to go through all the hassle just to get your cabin slightly quiet. Tesla should have done these in the beginning, especially at the price point..
Heres the problem, you used a phone app to measure DB its more preferably to be accurate with an apple watch DB app or an actual DB Meter, then your ears probably didn't notice anything much because you didn't add any product into the doors, start doing the doors and then the front wheel wells you'll realize.
@@willzbillzfam and also check out for the front wheel wells as those are also important to insulate that'll also decrease even more road noise that enters from there.
especially when I sound deadened my 13' CRV to the point its quieter than the 2024 hybrid touring crv with dual pane glass by 2-3db which is 50% more quieter. Also consider buying 80 mil kilmat, and then siless closed cell pe foam 150 mil and also add it to your plastic door panels for more insulation to absorb noise.
Most of the noise is road noise, insulate wheel wells will make some difference, low noise tires can also help. But the car is cheaply made from the start, it’s really difficult to quiet it down afterwards.
GOOD Work but The main reason for that much road noise for model y , is there is no acoustic glass in the rear and top and suspensions are horrible and tires no much driving comfort its just your sitting on top of a beam thats all and no proper sound insulation , the new highland 3 has acoustic glass evrywhere and newer suspensions and tires makes a huge difference , wait for the juniper to come..and save your money ..just buy basics .like floor mats ..and sunshades on top due to sun ..and nice wheel covers if your curb hitter..other than, your saving a ton of money on gas ...
Thank you for keeping it real, too many fake sponsored vids that hype these up...and ppl waste their money. I respect you did this.
Thank you!! We love a good honest review as well 👏🏼

Happy to help!
Dude, such a good video. Thanks for being so real and honest!
Appreciate it!
You’re honest. Most people would fool themselves into thinking it’s quieter.
Totally. We are hoping to do the doors and wheel wells next to see if that makes a difference.
Try a sunshade on the glass roof. I have heard good results on NVH reductions
Good idea, we will try it out!
😂
I was about to purchase kilmat butyl to be placed on the wheel arches. not anymore. thanks for the video.
Well we've heard from several people that doing the doors and wheel wells is where you will see the best results. We are probably gonna try it to see if we can get the Tesla more quiet.
thank you for doing this , your experience will benefit many people who are looking at these products.
Happy to share!
Definitely a thumbs up for testing this out on your Model Y. Appreciate the honest test results. I'll keep my Model Y stock, thanks to you.

I did like the same stuff on my Honda. I realize that the sound deadening is meant to reduce vibration of the metal, but not blocking sound wave. So for road noise, it just won't help. I think that some type of sound isolation cushion would do that job
Good to know
you only used Butyl, you had to use layers of specific materials for that. Butyl rubber, Closed cell pe foam, then maybe MLV. mainly closed cell pe foam is what well decouple the noise and then MLV will be blocking the noise.
I was about to do this same brilliant idea I had to my MYLR lol. So I had a new thought about wheel/tire areas that I have not fully looked at yet but what about spray foam in certain gaps and in the wheel liner areas as it seems to me that is where most of the noise originates from. Foam reduces the noise the best and I noticed my previous Lexus truck was exactly that, foam inserts in a lot of the paneling gaps and wheel and fender areas once I opened them up. Nothing we can do about more acoustic glass but my Lexus was extremely quiet. Figured they must know a little something with all that foam and noticeable extra carpeting and padding. Just thought I might throw that your way since you are now a pro at removing everything in the Tesla. Thanks you saved me a lot of time and money because I was about to do the same matting idea next month thinking it would be so great.
Haha, good ol UA-cam for the win! Someone else just commented that they did a liner and foam and it actually worked pretty good.
I did sound deadening on fender wheel well + A, B, C pillar + kick pad trim.
I can feel the difference how quiet it's in highway speed.
1. Fender Wheel well: I used anti vibration pad + thinsulate on fender metal + wheel well cover. But, it didn't bring much difference.
2. I worked on A B C pillar + kick pad trim filling with thinsulate. This made a huge difference and I can notice the difference right away without the decibel testing.
It seems like you haven't done interior trim sound deadning job and you will see the difference.
Good info! We'll look into this, thanks.
Probably a set of Tein comfort shocks would be a better upgrade. Maybe even take some road noise out since the stock ones are so stiff.
Will look into these, thanks!
Look up the rear hatch seal mod and hatch adjustment.
Will do, thanks!
I've been reading a lot and it seems that people recommend doing the rear wheel wells with multiple layers, 1st is butyl > next is closed cell foam > and last is massive loaded vinyl, each will have different roles, anti vibrations, absorbing noise etc. I'm waiting to do that with my rear wheel wells but not sure how many layers I can do with the side that has the speaker, wondering if I put too much there the speaker will not fit.
Interesting! You'll have to let us know if it works for you
@@willzbillzfam Yep doing that today, will let you know. Also the 5/16” OD vinyl tubing around trunk seal trick works for me, obviously reduce cabin pressure & some back noise. If you haven’t done that I highly recommend, 10 mins trick literally.
Question, did you also adjust the rear hatch stops to try and reduce low frequency vibrations as it acts like a drum.
Also, if/when you are ready for new tires, it'd be great to just see the difference a different brand makes.
No, is that a thing? Sounds interesting. Do you just loosen them and move them in a little?
Wheel wells and doors will be your most important spots to address. The floor will be minimal due to the battery and insulation of it.
We're hoping to do both of those projects next!
Thank you for a very honest opinion.
Appreciate it! Glad we could help.
Thanks for taking one for the team.
Our pleasure!
Sorry for your disappointing results. Appreciate your honest assessment. I wonder what the sources of noise are?
Thank you! We think it's mostly from the doors, wheel wells, and all the windows. Nothing we can do about the windows but we might try to do the doors and wheel wells.
Thanks for the honest video Willz Billz Fam. Making a big difference would be hard since you already have the smaller wheels, so it would take switching to Koni FSD dampers and insulating the front wheel wells along with the doors in order to make a real difference.
If you have Pirellis then changing to a quieter and softer tire once you go through these ones will also be noticeable when it comes to the low frequency rumble.
As for reducing high frequencies, apart from also insulating the doors... the Y has a huge glass roof which reflects most of the sound, absorbs basically none and also transmits some of it from the outside. What can be done is getting a roof sun shade
and then putting some acoustic foam between that and the roof, its thickness of course depending on how much room is there. There is acoustic foam with adhesive backing available, so it wouldn't just fall down.
Only putting the foam up there would be aesthetically unpleasing, that's why I'm suggesting covering it with a Y roof shade which are widely available anyways.
Best of luck with your projects 👍
Thank you! We're actually looking into the roof shade to see what results that'll give us🤞🏼
I regret that so much effort did not achieve the result. Thank you for your efforts.
Same!
Thanks!
Our pleasure!
thanks for all that hard work - i'd hire you at my company
Deal!
I test drove a MYP a week ago. I dont understand this sound noise issue i keep hearing about. It wasn't an issue in the slightest. I had radio off as well.
Agree, it's not THAT bad. We were just hoping for a slight improvement.
Didn't even realize it was you channel, just really liked the video idea. I hope you're enjoying Vegas, we all miss you a lot!
Miss you all too!!
Hi Durbs.
Buy an S. I had one for 3 years! Drive one to check out. Thanks for the work saving us the experience
We'll have to check that out!
Thank you so much for this video! I was planning to have this done for almost a thousand bucks at a shop, but I will definitely save the money for something else. Such a shame it didn't pay off for you, but you helped thousands of people avoid the same mistake 🙏
I actually have a 21 Model 3 and it's a well known fact that the 24 M3 Highland is much much quieter. People have installed the new Highland dampers to their older models and noticed a reduction in noise, along with a much smoother ride. So I believe a suspension upgrade might do wonders. Maybe you can get the dampers from the next Y version once it's released. I've heard some rumours that the new dampers use the same tech as Koni suspension, so you might also go for that even though it's more work and more expensive.
Glad we could help! Definitely expected better results but either way, we did the video to give an honest review and find a lot of enjoyment in that. We have been researching other products and came across ResoNix. The products are very expensive but the website explains a lot about the science and what it takes to actually get results (multiple layers to reduce sound resonance, absorb sound waves, and block sound waves). If we ever win the lottery, we might try it out.
I did the same on my 22 MYLR, the best result was when I put sound mats inside the fron quarter panels. Its very tough to get as deep as you want to get in there, but it actually made a much better response. I have not done anything to the door panels yet, but I have been told that will make a noticeable difference. Overall, not as dramatic as I had hoped, but I got a very noticeable improvement overall. I used cheaper mats also, and maybe spent about $125 all in.
Good to know, thank you! Sounds a lot cheaper than the route we went 😄
@chrisshinkle7224 I also applied sound skins package. There is small difference for rear passengers but not for front passengers. How to remove front quarter panels? do you have video link? I am thinking of applying sound deadening under the foot area of front passengers. This area is close to front door wells and may give better results. What are your thoughts? Thanks for sharing your experience.
As an owner, a very happy owner of a Tesla Model Y, I can only share that when I replaced the stock dampers with Koni Special Active, the road noise got NOTICEABLY lower! That actually came as an unexpected bonus, for I was aiming to improve the drive quality. I was looking for improved stability and reduced harshness. The Konis did excellent job! I wish I had the possibility to compare them with other aftermarket dampers, but there was no suck option, that is why I went directly to Koni. In my opinion, this is the first upgrade every Tesla owner should do! The effect on the Model 3 was even more pronounced.
Nice, we'll look into this! Thanks
What year Model 3 did you add the Konis to? I have a 2021 model three that I’m planning to drive 10,000 miles next spring and would really love to lower the road noise.
@@ted_jerome it would help on all models up to 2024 Highland when Tesla switched to dampers of this type. Along with that, using the smallest possible wheel size with a soft and quiet tire also helps.
After that comes additionally insulating the front wheel wells. And if you're nitpicky and also like better speaker quality, insulating the doors will add something also.
@@lukeblacksmith7422Thanks! Now to see if my budget allows for a Koni upgrade…
Great way to void your warranty lol. Main issue with the noise in the Tesla that is overlooked and my least favorite design element of the car is the ALL GLASS roof. It lets in a lot of sound while also reflecting a lot of sound that is already in the car. Compare that to a padded ceiling in a normal car and you can see why the acoustics in the Tesla suck. Take those sticky pads and just cover the glass ceiling in the car. I bet it will make a much bigger difference in the sound.
We like the look of the all glass roof but yah, not great for a quiet ride 👎🏼
I notice that only 2/3 of the rear wheel well has sound skin, and the other 1/3 remains with the cheap factory insulation (at 7 min 39 sec). Also, on the part of the wheel well that has sound skin, the original factory insulation was not put back on top of the sound skin.
Do you think putting sound deadener on that 1/3 of the wheel well, and putting back the cheap factory insulation in all cases, would have made a difference? Would it fit or it would end up being too thick?
I would think it would make a difference but only one way to find out! We want to do the doors next, and maybe some sort of screen on the roof glass.
I spreyed about 18 boxes of silicone paint for noise deadening all under it, the plastic covers also the four wheel wells but almost nothing changed, i did there for my amarok and also ford custom it was working great but not for tesla model y for this time
Bummer! That's a lot of boxes of paint!
This video saved me money. I was thinking about buying some of these products until I saw this video.
Glad we could help out!
Thank You for the honest info!❤
Anytime!
Thank you
Welcome!
Hi
I know what you did wrong. There’s a sound guy over here in the UK who sells similar sound deadening products for cars. He’s done a bunch of Tesla’s with great results. It’s the doors. You didn’t do the doors. He ONLY does the doors and sometimes the wheel arches but on the outside (by removing the wheels and arch linings). Try that in another video. Guaranteed to work. Just be careful with the rear doors as there’s a lot in the way. He doesn’t move everything as it’s impossible and no need. Go for it!
I think our next project will be the doors and the wheel wells!
Is there any information on these products from the UK? Links etc?
@@paulhodacs4235 Yes, loads. But I found this and its in the US so easier for you... ua-cam.com/video/go7_AkBc01s/v-deo.htmlsi=plNgw2gj-5Qu2vzE
I second the request for the name or link to the sound guy!
A lot of your road noises coming from the front wheelWells so if you’re not soundproofing the firewall, you’re still getting noise coming in there and then also the mass load vinyl works great but it’s a thick vinyl blanket that lays over your floorboard under the carpet that’s going to help a lot from the Floor, though you still have glass that’s single pain. And then, if you don’t have any sound deadening on your roof, and I believe that once the sound gets up and starts, bouncing off the glass in the car, it’s going to be hard to deaden it unless you put some kind of window shade on the inside to help dampen the sound.
Thanks, we're thinking of doing the wheel wells at some point!
noticed most noise come from the doors and the front wheel well.
Agreed, we might try the doors next.
Did your 2024 come with FSD shocks? Apparently the new model Teslas come with Frequency Selective Dampening shocks that make a huge difference.
I don't think ours did unfortunately. We're gonna try the doors and wheel wells next to see if that helps.
That's just on the refresh Model 3 right now. The dampers will fit my 2022 Model 3. I ordered a set at the service center and will have to get a 3rd party shop to install them.
@@That-Guy_ Best of luck! Hope you get better results than us
I’m surprised you went that far with the interior tear down and didn’t do the door panels. Most of the noise comes from there.
I know, we are kicking ourselves for not doing the doors. We plan to do them at some point though!
I like me road noice from my 2024 MYP.
MYP?
I bought the sound skins kit a while ago. I got most of the trunk trim out but then decided to abort because it took forever for me to figure out how to unclip various small electrical cables 🤣🤣. I also found a place to do the install but I didn’t want to risk adding new interior noises due to improperly replacing the trim pieces. I also messed up one trim piece near the rear passenger seat that I need to fix. Thanks for your review. I suspect the. 2025 model y will be a lot quieter just like the 2024 model 3 , it was like being in a crypt.
Haha, I want that crypt feel!
The amount of work you put in for that much noise reduction is extremely commendable.
We did it for you guys! Actually, we really expected better results but were open to a total fail just for the opportunity to make a video.
@@willzbillzfam It wont mean much but I did subscribe after watching JUST for the effort and your confidence to pull this DIY off. Impressive.
The reason these static noise dampeners dont work is because they tend to only dampen certain frequencies. Meanwhile that frequency may not match or vary from road conditions, to car condition, to tire condition. Hence for the same reason there is active noise cancellation in most advanced acoustic devices whether it is headphones or a Maybach.
Thank you! I was about to buy this snake oil.
Haha, happy to help!
perhaps try quiet ride tires? ...i have a 2021 toyota corolla hybrid that is just killing me on road noise. in order to save gas they cut down on car weight - probably the same with Tesla. Try teaching your kids the art of Zen car door shutting...... :)
Haha, they are slowly getting better!
Greatly appreciate your efforts to make a good record of your best effort to sound-deaden your MY! Sorry you weren’t able to hear a big improvement. After reading the comments, I think I’ll go after my front doors and wheel arches for my ‘21 M3SR+.
Good call! I think we're gonna attempt the same 🤞🏼
Thanks for sharing your experience here, much appreciated. Nah I wouldn’t go down that track, why? Because I have driven many cars and they each have their quirks. Road noise is a fact of life when driving anything. I have a lot of fun on a noisy tractor actually.😂
Agree 100%! We have a nice burley 2000 Chevy
Thanks for the effort 💪
You bet!
Try treating inside the doors. I mean it couldn’t hurt.
We're gonna try that next, Apparently that and the wheel wells is where most of the noise comes from 🤦🏻♀️
I think the biggest thing you can do is reduce rattles from loose clips behind plastic panels in places like the hatch and doors.
Agree, I think we're gonna tackle the doors and wheel wells next.
Read about a guy here in Norway that insulated the doors properly when they changed the whole speaker system to Focals. They had to remove the windows to put the insulation on both sides. But it supposedly made a huge difference.
The results you got were similar to people who just did the weatherstripping - “maybe a little quieter…”
For real, was quite surprised at the lack of results.
Ive heard the front wheel kits are the most effective for road noise! They make them for Model 3 and Y and cost about 150$. Could be worth looking into!
We keep hearing that, might have to look into it.
Did you try wearing earplugs?
Good idea!
So, it seems the weather seal/strip is the only thing that's worth it? I mostly have an issue with how loud my doors close on my 2024 MY
I think the sound deadening we got did help BUT we just need to do it on the doors and wheel wells to really hear a difference. I think it would help your door issue
@@willzbillzfam Thanks for the advise and an honest review!
Had my 2024 model y for 2 months. So far we think ours is pretty quiet riding. Depending on the roads we are driving on. That was alot to go through for no glory. My BMW 530i was much more quiet riding but much more $$ also dont miss putting in premium gas . Little more noise but definitely not terrible. Great and impressive try . Thanks for being honest.
Yah definitely a quieter ride right out the gate. I imagine they'll keep getting better and better with sound deadening. We don't miss gassing up either!
Lexus uses felt type liners in the wheel Wells on the outside of the car...
And it's nice and quiet? Haven't been in one in awhile
love that you buy a car that promotes it as THE ev.. and then you need to make it premium
Agree!
Great video, sorry about the results.
Thank you!
how much extra weight are you carrying, extra weight is less efficient
We're thinking all the materials are about 30-40lbs of extra weight.
You put product everywhere it didn’t need to go. Floor is pointless because you already have a massive battery there.
Doors, all of them (and yes your sound will improve).
Wheel wells
Trunk door.
Frunk bin (backside)
You also need a layer of MLV or fiber sound absorber ON TOP of your first layer of sound dampening (the same stuff you guys used in this video).
Tint your windows, use ceramic coating and tint your windshield too. Helps a bit with resonance and sound also.
My Tesla is dead quiet.
Ok, good to know! Would love to hear how quiet you got it from factory. Hoping to get ours there some day
Great experiment though! Think most of noise comes from windshield, fenders & tires. That noise reverberates w a glass roof too - sun shade may actually dampen more than insulation does. Thanks again
I didn't think about the glass roof, good thinking.
Who the hell is going to do all of that? Crazy.
Haha, us!! Results weren't as hoped for but was a fun experiment.
You didn't do the doors or the rear door, that's where the sound is coming from. Just tap on the panels and hear how tinny it sounds. I did a similar thing with ICE hyundai i30 wagon but only doors, trunk floor, so everywhere where carpet didn't have to be removed. I bought new floor mats, higher gsm than standard mats and got good results.
You also didn't hold the phone in same spot and you did door close test from the back. Post installation was different
No point doing tesla floor as you have batteries underneath no sound will penetrate through that from the outside.
Yah we're kicking ourselves for not doing the doors, hopefully gonna try it next.
"Loyal watcher and commentator" What was the preparation to get the leg stance on the car like that!!! Apperciate any recommended stretches or clothing ideas.
Haha!
It sounds like most of your noise is wind and also while testing your hvac was on that’s a lot of noise
Good points. We have since found out that the doors are also one of the main ways noise gets in so by not treating those, we missed out on actual benefits.
You didn't do the doors
That and the wheel wells is next up on our list!
Hopefully others will see this video and save themselves the time, labor and cost. They will owe you.
Results weren't as good as we had hoped, but maybe it'll help someone!
tY SURE SAVED ME FROM TRYING AT LEAST THE DOOR STRIPS.
Happy to help and appreciate the comment!
The biggest difference in noise comes from covering the groove between the front windshield and the rooftop
Good to know, thank you!
Thanks for sharing. I was hoping with all the material you guys put in, you will achieve Rolls Royce level of quiteness.. But that was disappointing. Maybe the material chosen is simply inadequate for sound proofing. I personally was thinking if I ever carry out soundproofing ill be choosing mineral wool sound proofing.. the stuff they use in residential buildings. But then, there probably is risk of fire..
The other risk which we just found out about the other day is not putting everything back together correctly. We were pretty careful taking everything out and putting it back in but still managed to route the wiring for the driver seat incorrectly and ended up damaging the wiring. We had to pay $700 to get it fixed.
There is no risk of fire with rock wool. It's completely non-flammable.
The main noise comes from the wheels, so the first thing you should always do is apply soundproofing material to the wheel arches. Additionally, you should remove the door panels and soundproof the doors, not the trunk.
Genius. What product works best for the wheel arches?
@@willzbillzfam seen someone use MLV but its hard to work around with. I suggest butyl rubber and then closed cell pe foam. ua-cam.com/video/NZlqfzl5fus/v-deo.html
Now peel it all off and return it 😂
Haha!
It sucks that you have to go through all the hassle just to get your cabin slightly quiet. Tesla should have done these in the beginning, especially at the price point..
Agreed. To be fair it is fairly quiet but we are nerds and wanted to see if we could get it even quieter!
I think the noise is because of the windows. Half the car is window.
That's is true! I always forget the entire roof is a window.
Heres the problem, you used a phone app to measure DB its more preferably to be accurate with an apple watch DB app or an actual DB Meter, then your ears probably didn't notice anything much because you didn't add any product into the doors, start doing the doors and then the front wheel wells you'll realize.
Yah the doors is gonna be our next project!
@@willzbillzfam and also check out for the front wheel wells as those are also important to insulate that'll also decrease even more road noise that enters from there.
especially when I sound deadened my 13' CRV to the point its quieter than the 2024 hybrid touring crv with dual pane glass by 2-3db which is 50% more quieter. Also consider buying 80 mil kilmat, and then siless closed cell pe foam 150 mil and also add it to your plastic door panels for more insulation to absorb noise.
Most of the noise is road noise, insulate wheel wells will make some difference, low noise tires can also help. But the car is cheaply made from the start, it’s really difficult to quiet it down afterwards.
Agree!
Go to your local Mercedes dealer but the sound proofing for an s class you can cut then yourself it costs around 1200 dollars thank me later
Go to know, thanks!
Bro, use your gym. I would be swole af if I had your gym. And i'm currently raising 2 under 2 💀. Great video though and very informative!
Our pleasure! Here's to being swole 💪🏼
GOOD Work but The main reason for that much road noise for model y , is there is no acoustic glass in the rear and top and suspensions are horrible and tires no much driving comfort its just your sitting on top of a beam thats all and no proper sound insulation , the new highland 3 has acoustic glass evrywhere and newer suspensions and tires makes a huge difference , wait for the juniper to come..and save your money ..just buy basics .like floor mats ..and sunshades on top due to sun ..and nice wheel covers if your curb hitter..other than, your saving a ton of money on gas ...
Thanks for the insight 👏🏼
PSA: watch this at 2x. Or TLDR: it was a fail
That's how I watch all video these days!
