Best part of the video: the last 15 seconds. LOL
Yeah. I laughed at that as well. :D Just think about all the people who see them knocking their cars, having a laugh and slamming their doors shut every now and then. :D
it is excellent
17:35 Spongebob and Patrick having a great time together. :D
🤣🤣🤣
underrated command lmao
It does change the tone to a lower pitched hum, which is more tolerable. Also db ratings aren't like a volume knob. An increase of 3db is a doubling of sound energy, or -3db is cutting the sound energy in half. So looking at your chart with your tires, it seems to be around ~27% decrease at 80km/h, 50% decrease at 100km/h, and a 20% increase at 120km/h, with an overall decrease of 0.6db or 20%. It does work relatively well. Is it worth it is a different question.
How we perceive sound is also different than the db measurements. It's generally reported that it takes around 5db before you really notice a difference in volume, and 10db before it actually sounds like the volume has been cut in half or doubled.
Can you compare the noise leaking from music? Play in both cars the same song en compare that difference? Same with calling etc.
Yes That is what I want to hear as well.
@Bjørn Nyland
I have gotten just the rubber seals and it makes a huge difference to sound quality in the car for the sole fact that it mostly eliminates the door rattle at higher volumes.
hahaha det last 15-20 secounds was PURE CLASS. Thanks Bjorn & CO for making this type of videos.
Greetings from Sweden
Thank you Bjorn! Best sound-proofing effort, side by side research and testing yet. Interesting results. I was hoping for better outcome. And gracious gift to your friend with the referral code too.
You should now test the power usage for heating to see if it changed from 1.55kW per hour in the test you did before
There no such thing as "1.55 kW per hour".
@@bjornnyland I think he means does it need less energy to keep the car heated because of the sound proofing insulation.
Don't think so. But due to extra doorsills maybe more comfortable because of less draft in the car?
insulation affects heat flow in a linear manner, where as sound is logarithmic, I think it will be close to the X now with the main loss remaining through the un insulated windows
Sorry that's an other way of saying kWh I just re looked at your HVAC test from a week ago, it was 1.5 KW, used for 10 hour period or 15 KWH. Now that the 3 is insulated you can see if it has made a difference
Fun video. :) You also should have measured with a frequency spectrum analyzer.
You can do this using the smartphone and an oscilloscope app. Try whistling into it, higher and lower pitch, also try the fft function on it.
You can also analyze the recorded sound afterwards with a spectrum analyzer software or a plugin for professional DAW. Maybe even the sound clips from this video can be analyzed.
This type of soundproofing will only deal with the high frequency noises. To reduce the low frequency rumble you need to go for something like leaded vinyl which of cause weighs quite a lot more...total car weight of this material would probably be between 50 kg and 100 kg...
Is that what Rolls Royce use? They have the best sound deadning in the industry and I think I read somewhere about the new phantom that there is over 100kg of sound deadening material
@@supaahflyy I don't know but very possible...
@@supaahflyy I had the Lexus CT200h. It weighed 200 kgs more than its sister model the Toyota Auris. The lexus was one of the quietest cars I have ever driven!
guy just throwed 1950 euro into nothing
100kg is a bargain, my car is already 1995kg anyways. And it runs just the same with 400kg in the boot with the pneumatic suspension
It's no ideal that you have 3 variables changing between the cars, wheel size, tire type and soundproofing. Even so, it's clear that the soundproofing is more pleasant, lover frequency. Both, however sound like an idling Enterprise, which is good shit.
The reaction from the nocking on the rear quarter pannel was priceless!
Knocking on heavens doors ... 😁 Well done guys, thx for that funny and interesting video!
Nicely done. I wouldn't undervalue high frequency reduction. This makes a huge difference in long term comfort even with similar overall db levels. Can't wait for the rain and gravel test.
I did a similar sound proofing in my Ioniq, except the outer door panels, and i came to the same conclusion. But I only paid around 100€ for Material and did the work myself.
Finally! Really love all about soundproofing! Thanks! I hope you can test megahjul summer tires 19 Nereus/Winrun for example and do some noise test between them .
Yes, and the Michelin Primacy as well.
Thanks for the video. I was wondering how much sound dampening we could expect if we did this, now we know. ;)
That last bit - priceless guys! :-D
The guys around a surely asking them self what are they noking on there cars 🤣🤣 . Priceless
Thanks for the detailed table. I see what you mean by the e-tron!
Nice taking it all the way!!! I’ve tried multiple door seal kits, and I have the roof band in place. What I’ve come to the conclusion is this... the road noise that comes in just is not absorbed anywhere. Not like a car that has a roof. It’s my belief that a lot of sound deadening comes from cars that have a roof with a liner and some insulation in it, like a party in a room with carpet, vs a room with hardwood floors (just echos)... and the Model 3 has the all glass roof (no sound deadening). Further most cars have doors with a window frame that buys you more seals around the window itself.
Good video, hope you are planning to do a rust proofing as well. It should have an effect to the noise too.
That was an epic ending!! Speaks volumes!!
thanks for sharing, nice to see the comparison. I noticed that the gray car is coated with vinyl and this will also reduce the sound of touching the sheet metal, so it doesn't give such a test compared to the car that took the insulation.
great job! I'm glad I stumbled across this video, because I wanted to do the same job on my Model3, but seeing the poor result I think I won't.
it
This job is right for car-audio enthusiasts, but I only wanted to do it for acoustic comfort.
I think it's better spend my money on good tires with low Db values
great experiment... it was a waste of money ... but for you i think it was worth it ... because you educated your viewers... it adds value to your channel .... but you showed us that it is not worth it ....
Me too :-)
The difference is quite substantial.
Did you listen to it with headphones?
@@bluebikerathar Agreed.
Should be more obvious effect on the sound system
keep on knocking guys! love this test!
I had the Hankook EVO on my model S ana was very impressed with quietness, efficiency and smooth ride. EV specific foam liner, designed for efficiency.
A lot of sound comes through the frame sides that are behind the rocker panels. Not sure how to describe it. But if you fill that hollow frame on the left and right side of the vehicle with sound deadening foam, it reduces road noise significantly
I wish you could provide some pictures/links so we knew what you were talking about
Close your eyes & just listen when doing sound comparison & you can tell every time the difference
The last seconds. LOL, perfect ending guys! Two little boys playing with their big toys xD
In North America, the 18" wheels come with Continental tires that have soundproofing inside (some kind of thick white foam is glued on the inside of the tire thread). It makes a huge difference they are way more silent than my Nokian R3 winter tires. Tires soundproofing is worth investigating. I haven’t been able to find anything to soundproof my R3 tires yet.
The 18" pilot sport 4 come with the acoustic tech as well and is an amazing tire.
I would insulate the doors and rear wheel arches on the inside. Is relatively easy to do yourself and also brings benefits for the sound system. The costs are, depending on the material, between 200 and 900 €.
I think it's totally worth it but I'm planning on just paying for the materials and doing it myself. Also, looks like it could use some more heavy material to deal with low frequency sounds too. Oh this'll be a cool project!
The biggest misconception is that sound deadening "removes" the road noises. That is not the case. They simply absorb the sound waves and vibration and convert them into a different frequency that is less audible to the human ears. The noise is still there, but at a different frequency.
Exactly what I pointed out.
As usual a great video - my personal experience is trunk and door/window sills are most important to isolate. Wheel arches do not matter all that much - especially the ones in the front.
Why don't You think the wheel arcs matter?
My impression is that most of the noise is actual roadnoise, from the wheels. You can also hear the difference in the videos between the rough asphalt and the smooth one.
Both cars needed to have identical tyres to make it a valid test. I really like your videos keep up the great work.
Check the table. I did tests on the exact same car before and after soundproofing. Results were nearly identical.
@@bjornnyland Most of the noise ir tire noise. Try getting the wheel wells from inside sound deadened. Also, the bulkhead between cabin and frunk. Those are the best places so start always, don't know why this guy didn't attack those places
@@bjornnylandBut using a spectrum analyzer would've shown if there was a difference in Soundlevel at some frequency bands. Just measuring the max dB is not right.
Love the ending😂
With headphones there are clear differences in the video to hear, even with the wind noise. The lower frequencies are less annoying for me. I think most important are the wheel arches.
And yes: smaller rim, higher tires and less running noise. Audi has done a lot for the acoustics (soundproofing glass, insulation, etc.). Thanks for the information. knock knock LOL
Interestingly Tesla's passenger compartments are built directly on the frame as are the motors, so Db levels are not effected but the frequencies are when soundproofing. I think you could get the same soundproofing effect (way cheaper) by soundproofing the doors and using thicker rugs, especially against the front passenger foot wells.
Maybe wheel arch and door package would be best option and cheaper, prob only 1.5 days to fit too.?
I did a similar thing on my Passat B8 and mainly found a frequency change and interior pressure change that I initially found unpleasant. In cheaper older cars like Peugeot 206 it made a bigger difference. I have been contemplating weather stripping and soundproofing on my model 3 2022 but after seeing this video I think I will give it a miss. Switching from Hankook Ventus EVO 3 that the car was born with, to Michelin Pilot Sport 4 S and curious if that will make a noticeable difference due to the acoustic foam. Have the 19” wheels
Hi. Most noise came from the windows, thet mean you can stir way more or thicker pads it will not reduce the noise in the Car. It gives you only the felling of proper door that's it, and the knocking on the door ore fender shows only the mode of the part ist moved, NVH science. Try to replace the door Windows and you will listen the different look at the cars like mb s- klasse ore bmw 7 series the windows are twice thick an more.
Music studio soundproofing knowledge tells us that to remove low rumble the panel should be couple centimeters thick, and ideally should be similar to stone wool. But then comes the problem of the fact that vibrations are passed through the structural elements of the car, and get in though the gaps in the layers (like windows, air inlets), so there are limits
The Sentry is probably going "WTF???" with all that knocking.
You are funny and informative.
It would be interesting to see "partial" proofing. Only wheel arches - vs only front doors - wheel arches + front doors - vs MC Hammer full treating) to see where the key improvement is found (in practice).
So if Pavel is tempted - get a deal with the proofer. Testrun against MC Hammer after wheel-arches done. Then after front doors done (etc)
That would be consumer advice at peak performance.
Oh - while I am at it - I wonder how traditional rust-protection (Tectyly type) in the wheel arcs would help. Imagining how that healthy treatment (for Scandinavians) + door isolation would pan out.
When i watch you both knocking on cars that is funny but the end was the best and great that are you helping the pawel to get more referrals because you don't need it you already have 1 million km of free supercharging but for the soundprofing i dont think it is worth the problem is in the windows 👍
your car is lower frequency, more pleasant. Im currently manageing 71db with no added insulation in a 17yo 552 000 km audi a8l on old hardened continental 265/35 20inch, rough asphalt. On new asphalt i'll hit in the low 60 and even tickle in the high 50 at 100kmh. Im thinking of doing this to make it quieter. I think tires need sound deadener inside of them, just like in the maybach and some rolls royces
What they did to bjørns car was mainly to reduce resonance - the small vibrations of metal plates. They did nothing for road noise or wind noise. Seems that they used lots of time, energy and money not accomplishing much. I am astonished that people haven't taken the time to understand the challenge they want to solve. They just jump into it and make a half baked cake. To demand money for such job seems impudent. They should of course - after they removed the panels - have added Mass Loaded Vinyl to the entire cabin to block sound and also added foam to absorb sounds and vibrations. check out these guys for instance www.sounddeadenershowdown.com/
Thank you so much for this great video. I was hoping that the sound-proofing would make a much bigger difference, but it did seem to help a little. A few observations:
* I think wheels and tires are still the most effective way of reducing road noise. Hence I will not be getting the performance version of the Model Y I have ordered, since reducing road noise is more important to me than showing off with quick acceleration (and it's much cheaper, too). But I wish I could have both.
* I think the gaps on the roof are gutters to allow water to run off when it is raining. Without the gutters, I think rain will flow off the roof into the cabin when you open the doors.
* I would like to have seen a test of sound leakage with hands-free calling.
* It is too bad that Tesla does not offer a sound-proofing package as an option. This could be done so much better, cheaper, more efficiently, and more effectively, if it were engineered into the design and done at the factory while the car was being made.
More reasons to avoid the Performance version of the Model 3 (and Model Y) with its non-optional large wheels, low profile tires and lowered suspension are shown on this Engineering Explained video: czcams.com/video/H6sPc9dFsGw/video.html
In the rain it will make a huge difference too, the soundproofing!
Could you try to measure sound with/without some absorbing material against the glass roof? (Maybe your blackout/camping panels)
Great job with the video.
The only downside to soundproofing a car is spending all that money on material only to reduce sound by 3db isn't worth it to some. Cost vs diminished returns. Most people don't notice that much of an audible difference and will usually be unhappy with the results.
Pawel looking fresh with that model 3
Question: could Tesla use the multitude of speakers to create some sort of active noise cancellation? Maybe that would be a cheaper way to go for at least a small amount of sound attenuation.
Would it be more of a change had they removed the seats and carpet and placed the sound deadening material on the floor and fro my firewall? From what I can tell between the S and the 3 is a lot more noise seems to come from the windows and the floor area.
honestly think most of the noise comes through the glass, the side glass especially seems way thinner than what was on my eGolf. Any products that help that aspect?
i would like to get the soundproofing .. but i should definately get paint protection film first .. that one is more important for me since i normaly dont drive for longer than 1h at a time
The end is hilarious 😂
In your video, most of the sounds we heard came from tire noise in wheel wells, so maybe if they tried again with heavier insulation just in the wheel wells, it could cut the sound a lot.
The sound from the wheels goes via the suspension and the springs directly into the cage. Cannot really dampen this.
@@whuzzzup You are partially right, its hard to dampen yet it can be done by replacing a few steel parts with "quiet steel" parts as was done in the Lexus over 15 years ago.
It helps on higher pitched sounds but not much ,most of the sound reduction comes from windows if the glass thicker like on high end mercedes and rolls royce that use about double the thicknes of ordinary cars and all the sound damping is done at the factory,plus the weight of the cars are a lot more than ev cars that are made to reduce wieght so ev cars will always have noise issues but rhats is just the nature of ev cars good or bad .
The cost is too high but I love the results. The high frequencies that were cut are the unpleasant ones.
It sounds like the fundamental structure of the car could be better from a noise perspective. Not a lot aftermarket can do there. :/
-Do you think the glass roof is also to blame? (And if so - have you thought about a custom cover for it, like with the sun shades?)
-Curious to hear your long-term review. It sounded a little less offensive to me so I wonder if it was enough to make road trips easier on the ears.
-Acoustic glass replacement where possible? Acoustic tint/film? (sounds expensive though..)
Not worth it, but cool test nonetheless. Great entertainment as always.
The glass roof is the problem. Cover the inside with a blanket or foam and you will see.
I don't understand why Tesla doesn't make a model without the glass roof... The car doesn't suddenly become 50% more premium when you can see through the roof!
A roof curtain would help soundproofing and also isolation but you can open it when you feel like it.
Glass roofs don't add much noise, if at all, mostly because the wind over the car is very much laminar. I hope, of course, that Tesla uses laminated glass for it.
@@gvaley But as hard surface it reflects downwards sharp sounds from inside..
Glass roof doesn't change anything (except that it's stiffer than metal roof). The gaps between glass panels cause some significant noise but it's quite easy to soundproof that.
I wonder how Pawel's vinyl wrap or bjorn's ppf has on the sound. Sounds to me like it could help a slight slight amount. Also what about window tint.
dB scale is logarithmic so small changes in the dB number equate to significant differences in perceived sound. even 2-3 dB is a significant improvement. Whether its worth it is a matter of personal preference. I suspect reactive sounds (going over bumps, stone chips etc) will be much less as the panels are less resonant.
+phil watt But the problem here was that in two of my measurements, the noise went *up*.
The drop is high/mid-range noise is perceivable from the recordings. But it means low frequencies are more detectable. I think brands like Lexus use foam and other soft insulation materials to block low frequencies.
Foam doesn't block low frequencies - only the heavy butyl rubber material dampens the low frequencies.
You need mass loaded vinyl or something similar to block tire or engine noise. And you can't just slap it in but you need to try and seal as much as possible. If you open the windows of a house near a busy street even a bit you have almost all the noise, not much difference with it completely open. Of course it's the same with cars.
You can definitely hear the different but not as much as I thought it would be from the start of the video showing all you got done to the car
I hope shops start offering this in the US. I mean I think I could do it myself, but this seems like something a tint installer or clear bra installer might offer.
great start, but the trunk is missing a layer of mass loaded vinyl which should go on top of the vibration dampening material. this would help more with road noise.
They didn't use any mass loaded vinyl in the car for some reason. Dumb because it would make the largest difference in stopping sound waves over all the other material.
If you want to test same for Model X I am turning mine over to Bilkomponenter for full soundproofing next week (and LED bar addition).
Interesting data Bjorn, thanks. Sound meters are not filtered to match human sensitivities to different frequencies (which is somewhat a subjective matter between people anyway) so you may find that you like your sound-proofing more than the results indicate. Or not. Or you may be a victim of a placebo effect. Or the beneficiary of the placebo effect :-)
Seems like the soundproofing removed the high frequency sounds. It's noticable on both rough and smooth asphalt, but more so on the smooth one.
You need a second layer of sound proofing, and also the rear doors should be better , most of the noise is from the back
It would be cool if they could put some more damping panels and maybe part-fill cavities (where you don't need to access things) with some kind of foam or something.
The sound frequency is different and does make for a more muffled sound. Remember that there is a huge amount of glass in Tesla's which you can't soundproof. It should also make the car warmer in winter I would think.
You absolutely can soundproof glass. Laminated glass has been out there for decades. Construction industry has even more products available to play with.
Maybe it’s about the sound transmission from the wheels directly through the car. So bushing, ball joints, strut connections. The frequency is better in yours.
The last seconds were priceless 😂😂😂
Does anyone know if someone does this in the US? I have one of the noisy classic Model S and would be interested in soundproofing.
Just do it yourself.
Audio shop
Dynamat, Kilmat etc
Good conclusion, not etron but better.
Now that the sound deadening has taken care of the higher frequencies, next step is getting some bass trap acoustic treatments
NIAtoolkit except bass traps by definition are very large compared to a car interior due to long wavelengths.
Fill the trunk and frunk up with folded blankets would give the bass trap effect, but hardly practical
Would be interesting to see a comparison between different tires according to their dB noise specification. The standard 19" tires (Hankook S1 Evo 3 in my case) have a noise level of 72 dB but you can get ones that have a noise level of 68 dB (according to dackonline.se). F.e the Goodyear Eagle F1 tires.
You can get an idea here:
czcams.com/video/DOABLgDf3N0/video.html
And here:
czcams.com/video/kJWOyJxLCao/video.html
@@bjornnyland Thanks. Watched both these videos and i guess that the conclusion from them and the soundproofing video here is that it's better to switch to low dB rated tires then to add soundproofing material. At least if road noise is the main concern.
The most difference may come from the sound system having far less vibrations resonating throughout the car body.
i think it is big difference in sound profile.
It's really money well spent as you are more often in your car than in your bed! ;)
That's a big difference in the quality of the road noise that must add up on long trips.
The read doors seem to be a pain to access, the difference in sound insulation between front and rear door is quite noticeable.
Maybe ask one of your friends when they'll be changing tires so you can both do it at the same time with the same tires and wheels for a more accurate measurement.
By the way, I suppose you were driving both cars at the same speed, but was it at the same gear too and were both cars charged with the same kind of electrons? I am pretty sure the noisy car was driving in first and only gear... ;)
I think you’d need more than these thin soundproofing panels to make a lot of difference. And that will add weight. E-Tron is heavy for a number of reasons.
What is a shame is that an expensive car like this needs it in the first place.
Err.. Model 3 is not expensive compared to e-Tron, Model X and I-Pace.
Bjørn Nyland sure, not compared to them no but it’s not a cheap car. We are somewhat shielded from the price in Norway but in reality this is still a premium price bracket car. And how much does soundproofing at the point of manufacturing cost anyway? Much less than you paid I’m sure.
@@SeriouslyJaded Proper factory sound proofing is probably more expensive than you think. You can't just slap on some material inside the car as done here. It needs to be designed into the suspension and chassis to get a good result on rough textured assphalt.
Looks like text is wrong for 19" smooth tarmac.
Deff got rid of higher frequency noise. If it was 10k nok may be worth it.
I can hear noise reduction on MC hammer yeah no doubt the car is less noisy
at least you will not hear anything when you run something over..

Knock knock :) Maybe you have to try with Digital Sound Meter, as always great video.
My sound meter is as digital as you get it. It logs the data for me.
@@bjornnyland oh shieeeeettt, forgive me, I have not expressed myself well.
I wanted to say that for the data of Mr. Pawel with MICHELIN PILOT SPORT 4S 235/35 R20 92 AND XL (E A 71 dB) you will use the soundmeter to put the data in your noise list of all cars.
Tires of the same size but different brand may vary a lot
Thank you very much for all the tests and trips that you do for us, I do not get tired of watching your videos, good shieeeetttttt! :)
Curious to know if such service is offered in Canada.
Most of the noise comes into the cabin from under the car. The one spot it seems they didn't cover in this package. The most important spot as well if your going for reduced road noise. I have my car covered from head to toe and it not only made the ride so much quieter but much more comfortable as well. If you miss a spot but cover others it can make it where the spot that isn't covered easier to hear noise from now.
Hello. Can you describe more about your soundproofing ? How much weight it adds to your car and did you soundproofed car arches from the bottom ?
@@elbowablins5814 i think total it added over a 100 lbs. probably close to 2 if im being honest. i didnt do every last inch of the car but the full roof,floor,door and trunk. Some of the side panel areas at a later time cause i had alot of left overs and was bored one day. not sure what u mean by arches?
@@Carlossteezyblunts wow, Thats a lot of extra weight which will reduce my Tesla speed.
@@elbowablins5814 yeah its like riding around with a passenger who weight 150ish. my car still takes off just fine. lol
its them bushings, bearings, those transfer vibrations vrom wheels to chasis and thats the reason why sound proofing didnt help
You should measure the decibels inside the car while your friend knocks on different parts of the car. Then compare it to the other car and see which parts of the sound proofing is actually in your option worth the installation.
To my ears, that's a huge difference.
Also when you do test like this you shoul us C-Wight on your dB measurement .
A-Weighting cuts off the lower and higher frequencies.
The "C" weighted sound level does not discriminate against low frequencies and measures uniformly over the frequency range of 30 to 10,000 Hz. This weighting scale is useful for monitoring sources such as engines, explosions, and machinery.
More info here www.noisemeters.com/help/faq/frequency-weighting/
How much did the material and work cost?
That "rough asphalt" would still be smooth in Britain
Bjørn please be so kind and test your battery degeneration. There are some tools and devices available to read out the exact data from the battery cells.
For example: total DC-charging, total AC-charging, total recuperation, Cell voltage, cell degeneration, etc.
Hi Björn. Have you seen the automatic Frunk and Trunk opening that is sold by the guys in the Netherlands? Looks great in some CZcams Videos. Can be used via the Tesla App even. Thanks for the Video.
Yes
A Touareg is 46db on a good road - 67 mate is ridiculously loud I am assuming those are DB numbers in chart.
46 dB is way too low. I don't trust your numbers.
With headphones there is a clear difference, but that difference might be because of different tires\wheel size.
