You perfectly showed with the cymbal, that a small patch on a large surface area is enough to stop waves in a material aka sound. So there is absolutely no need to cover your whole floor with sound deadening material....!
Hi PJ. You're right. Moderate amounts of deadener make a significant difference. Once the middle of a panel has been covered, the additional deadener covering the panel has diminshing results. Auto manufacturer's will engineer sound proofing to a dollar point, researching the optimal positioning for deadening to just meet consumer expectations. Vibration dampening mats are most effective on single skin metallic surfaces. It is unnecessary to apply deadener to over-lapped metal sections, top hat, chassis sections etc as these areas don't resonant. To engineer a car it takes some skill and technical analysis to pin point key areas, in reality most people will cover everything as they don't mind spending a bit more to ensure they have achieved the desired results. With paying customers, most people want everything covered. Keep in mind that this is one stage in controlling sound in your vehicle. 😎👍
Glad people are making videos explaining this. It's so annoying when I'm looking for sound insulation and everyone just shows me butyl deadener lol
Thanks mate. Yes, that is just one component. Good luck with your project.
Love the fact that you put t on the cymbal as an example. A few of us did this to the underside of them in our music class at school, needless to say, the band were rather concerned before they looked underneath
😆👍
Very well stated and presented. Most newer vehicles do not have an issue with the single most annoying source of noise in a vehicle, engine noise coming from sheetmetal openings. If you are doing an older vehicle blocking airborne noise can be tricky but the tiniest of holes will tank an otherwise good installation of sound deadening material.
Don't forget to check and change door seals on older cars. That includes window seals
What an EXCELLENT description of the different types of materials. This helps me out a ton as I'm working on dealing with some resonance in my MX-5 this week.
Thanks again, I really appreciate it.
Bedline it inner floor and bottom...
Stone chip proof and its sealed from elements... loose the carpet... is the car a house from 1970?
@@octaneartllc If you don't have carpet, what would you have instead?
Same, I am here to learn and work on sound and heatproffing better my MX-5. Trying to do it with the least weight adding possible with the biggest return on sound and heat proofing
@@89andresp how is going? How much weight did you add? Is it worth? Thank you 😁
@@Moriggia Hi. Good and you? I haven't done this. It requires quite some free time that I don't have yet, or at least not desiring to spend it on my Miata. I have a few other things to install it plus repairing a scooter and I have had 0 rush on doing any of that. I work remotely and have been using my car only about one day a week in the past 10 mo. But if I happen to do this, changing the tube from the intake before the separator seems to help with engine noise (not removing the duct for the noise but changing the big section for a different material that is harder and transmits less outside undesired noise), plus sound proofing maybe mainly on top of the back wheels is something I will definitely do, just not sure when. I would like to heat proof the doors and the whole cabin wherever possible but I haven't found what to use that isn't heavy, is durable, not that costly, and is not a disaster/big problem to install as the weather in south FL is definitely one to consider. I installed window tinting in the front windshield, the clearest one one found and a good quality one $150 in Miami, and it made a big difference in temperature and glare (more comfortable driving) and no issues driving at night. Also, no issues with police as it doesn't even appear it has window tint in the windshield. My favorite simple mod so far.
Great demo on the cymbal! That stuff is the real deal.
Great explanation. Teaching and sharing information (not emotions) was what the internet was originally created for.
Thank you for the feedback 😎👍
Not really. but ok?
I thought after porn went from beta-max, VHS, DVD, that the internet was the next medium for porn.
@Captain Buff The Third Sorry dude, but those feelings are nonsense. Logic, reason and understanding are the real answers.
@Captain Buff The Third You're not understanding. Logic, reason and basic events are all that need to be communicated. Beyond that is manipulation.
Thank you so much. What a great introduction! Now, to pick my deadener...
Thank you Haylee 😎👍

So useful I watched it twice. Thanks!
A great video! What about a video on common areas to insulate. Spare wheel wheels, under seats, wheel arches etc etc?
Wow. I was pretty skeptical of not needing 100% coverage, but I'm a believer after watching this.
Best video on the subject. Thank you very much.
Thank you Hung Pham 😎👍
Great video, very thorough explanations and very knowledgeable

Great video, just what I was looking for.
Thanks DJ. Good luck with your project.
lookin for a video like this for a long time especially on what to do to get rid of heat comin into the car
Hi firefox01 Glad that you have found the information you have been looking for here 😎👍
How about just driving the car and taking decibel measurements before and after applying the insulation material?
Its not that easy. You would have to average HUNDREDS of miles over the same roads in the same conditions (traffic/temps/weather/etc) and then do it again with the treatments in place. I know. I've tried. Ive also tested vibration damping products in a controlled envinronment. While I dont agree 100% with everything here, this is one of the most accurate descriptions on youtube on how to fully treat a vehicle.
People have done it. Insulation, depending on the vehicle, is good for between 5-20dB of sound reduction. Really dependent on vehicle and how much you use.
@@gymkhanadog Taking short measurements before and after are misleading. Too many variables. Just a difference in temp changes air density and therefore noise levels.
@@chrispurdue5762 I'm not looking to argue, but saying that subjective testing, even short term, is worthless is also misleading... We aren't talking about putting a used vehicle in an anechoic and doing before and after measurements. That would actually be good science. We're talking about subjective testing in the real world. Which is why I said 5-20, which is a pretty big sound range. The difference of 5 dB could mean damaged hearing or just a very uncomfortably loud sound. Remember, sound is measured in a base 10 log unit. Factor of 10 to make it easier.
@@gymkhanadog I can agree with most of that. I simply feel its important to make sure people understand that these tests need to be done in as controlled of a manor as possible before making claims. Having worked on objectively testing vehicle sound treatments for the last 8 years, ive fought for the entire time to discredit claims that products such as peel n seal are equivalent to products like Dynamat based on other peoples subjective "knock" tests, etc.
Fantastic information. Really well explained
Thanks for the feedback Paul 👍
Great explanation man. I Will do this way in my Xterra. Greetings from Brazil!
Thank you! Good luck with your project 😎🤙
I've watched this and truly appreciate the explanation. I will order from them, they have earned my business and I had a helpful email as well. Nice, quality people
Thank you so much! Good luck with the install 👍
I use 10mm cork pannel on my van... works ok, great for sleeping inside
Also very reasonable prices and finally some mass loaded vinyl carpet underlay replacements you guys really have covered all areas of Sound treatment and turning a tin can into a luxury feeling vehicle super impressed I see a comment from five years ago well bugger me no one told me lol although I did find some cool stuff at Jaycar that was also reasonably price and came in rolls like a poster which is far better than saying stinger roadkill sound treatment in a flat box where it's all stuck together. Wish I had known about this ages ago lol

I was a courier and once had to deliver bank bags that were vinyl and cloth in a Sentra. I had 300 pounds of sound deadening for a half hour - it was amazingly quiet, then back to "noisy".
Try it yourself : pack your floorboards and trunk with towels and clothes about a foot deep and go for a ride.
Hi Peter. The effect was two-fold. You stopped vibration in the panels by adding weight and you also created a sound blanket for externally generated noise. 👍
Excellent!!!
I appreciate how you showed the dampening on the cymbal. Also, about how a sound curtain behind seats is enough, instead of everywhere. That was a great video, very clear and easy to see how it all works together. Thanks.
Thank you for the positive feedback 🤙
Great video mate, just wanted to clarify if improved stereo sound is covered in general sound deadening or would you look at something specific for that purpose?
Hi Steve. All of this sound deadening is going to stop speaker panel vibration and improve stereo quality. Car audio guys will skin both the outer and inner doors if there are speakers in them to avoid the rear sound waves cancelling out with the front sound waves. It will also make the door act as a speaker enclosure, maximising sound pressure 👍
Great video explaining the basics!
My first car that I put sound deadener in was a 99 grandam gt 2 door. 100% coverage. It dropped decibels readings up to 15db. It was a massive improvement to the cabin quality. I spent a lot of money on it too, but it was worth it cause I had the car 10 years. Now the cars I buy don't really need it to be honest. If I were to spend that amount of money again on material the diminished returns wouldn't justify the cost. My Acura TL is already quiet for the type of driving I do now. Plus I spend good money on tires and it shows. Finding a quality tire made a world difference in the cabin.
yes tyres do matters.. specially youkohama advan db
The problem is good tyres especially Performance tyres are loud.
When going over bumps there is more resonating thump from the back, will soundproofing the trunk and spare tire space help reduce that noise that sounds like bass speaker.
thanks for the advice
Great explanation.. love from india! Thank you🙏
Glad it was helpful!
that cymbal demonstration shows really well how little of the vibration deadener you need for vibrations. now i assume you still want good coverage for stuff like blocking your exhaust because even though its vibration deadener it is also a sound deadener with butyl rubber
Using the symbol as a demo is brilliant
Thanks for a clear explanation of the different materials / applications!
Thank you for the positive feedback Michael 👍
I lined the interior walls and door of my clothes dryer while I was replacing the blower/fan. Now it's better than any dryer I've ever used! Did the same thing on a noisy steel drafting table too.
😆 nice work 👍
That is genius!
@@willfinney6598 Thanks! Similarly, I filled my 3-ton floor jack handle with spray foam. No more clanky handle!😀 AH... and maybe I'll put some sound deadening on my 4-way lug wrench... Just though of that!
Not a bad time to replace the bearing axle for the dryer drum while it's all apart. No more squeaking! Much easier to do than the blower in my opinion. (if your blower wheel is stuck on)
Been looking for this sort of Information for ages! Subscribed :) any chance your sound deadening is lighter than most stock ones?
Thank you Charlie Bishop. 😎👍 Sadly no. The problem is that you need to add mass to the panel to reduce the vibration. In saying that though, the mass loaded paints can be lighter depending on how thickly you apply it. Keep in mind, if you go too thin it won't have the required mass to deaden the panel.
Hello, nice video. What are your thoughts on Tecsound 50 Acoustic Membrane? Some say it works even better then MLV?
Very informative
Thanks Jason
Brilliant explanation of the importance of understanding the science of insulation and moisture
Ideal products for campervan conversation
Thank you for the positive feedback Mohammed 👍
Curious to hear how crucial the added Stage 2 foam layers are to reducing road noise? I’m in the process of applying the stage 1 butyl and now a bit concerned that I’ll have to also buy and install some MLV or something of that nature to reap the full benefits of it?
I liked the mention of running the MLV/CCF treatment on the rear seat backs since that was the method I plan to do in my car, to save weight and material. However, I was wondering, with a subwoofer in the trunk would this affect the low frequency bass coming into the cabin? I have 1 10" subwoofer in an Integra, aimed at the rear glass, and the removeable rear deck shelf will likely not be treated. If no one has an answer for me, I'll try out both ways in the coming week starting with treating the seat backs and follow up if I remember! My main goal is to kill road noise, something the Integra is plagued by being a cheaper 90's vehicle.
Hi Tom, if you had a sedan with a closed off trunk/boot and you lined the back of the back seat with MLV it would reduce the amount of bass coming through to the cabin. Because you have a hatch, the bass will be reflecting off the back window/hatch and going back to the cabin. Your removable parcel shelf panel will be the largest factor that will be blocking the bass from coming through. If you want to reduce road noise we would recommend applying MLV or Insulayer to your trunk floor, wheel arches and trunk side walls. 👍
Nice explaining then i was outside took my interior apart and now need a big welder some metal then sound deadning lol thats how it is to have an old jeep cherokee from 95
Nice video friend.
Thank you Albert 👍
Helpful vid..
Cheers mate 🤙
You guys should do one specifically for the Tesla Model 3. Everyone is complaining about the noise. You'd do really well.
😆
Would be nice to see some links to these products, or others like them in the description
Hi Singh. You can find all of our products here www.carbuilders.com.au/ 😎👍
You should consider providing links to where we can purchase the product and set it up as an affiliate so You get a little kick back for the referral. Great info, I had no idea there is even this many options.
Thanks Alex 👍
that cymbal trick btw, you will get similar effect with any random blanket
Nice Love from PUNJAB...
Thank you 👍
Concrete works best hehe.... I like your two layer foam and mass loaded vinyl. Using all three..deadener, foam and vinyl makes a big difference especially in boot floor and under rear seat.
I'm using Butyl + Sound Bar(MLV) + Felt ..each for different purpose, Butyl to reduce vibrations, Sound Bar to block the sound and Felt to absorb sound :D
EvroNetwork That is the way to go. I dynamatted a car and was dissapointed in the results so I used foam as well...and it still wasnt good enough...only when I added Mass loaded Vinyl did I finally get a quiet car..I was driving over 1000kms per week on rough asphalt...you know when your car is well sound proofed when you hear that Ssshhhh sound at high speed....
Thanks mate. You just saved me a lot of research 👍
Thank you for the positive feedback MegaSkyline69 😎👍
When I close my driver's door, strangely, sounds like a hollow tin can, but the other doors sound fine when I close it. I seriously need to add this to my car, sometimes its small things like this that make me feel my car is complete if that makes sense.
The noisiest thing in my car is the engine, even with new engine mounts, I hope when I buy this I will get a huge noise level improvement, and the insulation as an added bonus.
If a small section kills the resonance noise, could you just put small sections throughout and then use foam for outside noise?
Hey this stuff looks like a great option, just wondering how it would be removed down the track if ever needed?
Great video, very informative. I need to find one this like this in English.
Thanks Luke
“Cotton-jute carpet underlay” I had to turn captions on to figure that one out, lol
😆
I've met Aussies here in the USA. It's kind of like meeting cousins, especially if they're from the rural parts.
You guys are big on self-reliance, you got killer critters (I wish we had Kangaroos!), and like US you got started by running afoul of the English authorities!
😆🤙
Mazda 3 models BM / BN needs this....
Yes, I do have a question.
How thick shoukd I use the deadening mats. They varries around 1-4 mm in thickness.
I was thinking around 3.0mm will be a good choise.
They look like great products! Can you get the 1st. (rubber) layer off if you choose to later? Also, is there ever a chance of water getting under it and eventually rusting the metal under it? Just making sure because I would be putting this on my 34 year old Dodge D150 truck with only 26 thousand original miles on it. It's like new so I am extremely careful what I do to it.
The reason for my concern is the aftermarket rustproofing that is installed the most in the northern part of the country is a "rubberized" coating that is sprayed into the doors and the undercarriage and in time it pulls back enough to let in water and salt and the moisture stays there and just rots everything right through! I have seen frames of new trucks so rotten after less than 10 years old because of this issue that they are totalled!
Hi thoms_here I understand your concern. Yes, you can remove the butyl rubber once applied. It takes some elbow grease but can be done. We replace it once a year in our demonstration half car that we take to shows (to freshen up the display as it get constantly touched and rubbed). Unlike the old bitumen deadener, which would crack and allow moisture underneath it butyl doesn't harden and actually becomes tackier in warmer weather. Butyl is used in plumbing applications and you can see in another video we did that it creates a water proof barrier even when in a vertical application. ua-cam.com/video/tNnmyFO8lcw/v-deo.html Good luck with the Dodge, sound like a nice ride 😎👍
I'm thinking about filling fender cavities with expanding foam. What do you think?
Just subscribed to your channel,I just wanted to know if you are just a spokesperson for this company or if you will do other things then sound deadening? Thanks just asking because you sound very knowledgeable.

link for car builders sound deadening material?. Subscribed
carbuilders.com.au
I'm getting this. The road noise on coarse chipseal in Australia is so bad.
you probably won't see this but I am planning on reducing the car and street noise in my '95 Miatas cabin. I was wondering how much sound deadening you would recommend, since the car is relatively light and I wanna keep it that way, so the premium 2nd stage material is out of question. Should i just cover the entire floor with the first two materials?
Great 👍
Thank you! Cheers!
Thanks.
😎👍
who makes that thick mat? nice video also what's the mm thickness
Hi ALL KNOWING BILLY. This is a Car Builders Mass Noise Liner. You can see them here www.carbuilders.com.au/interior/ 👍
Great stuff
Trying to design insulation to suit a 25 yr old Civic track car that I still want insulated well enough to take the missus for a fast, not so noisy/drone weekend blast.
Should I just give you a call? (I’m in Oz)
Hi mate. Yes, definitely give us a call (03 8777 0960) and we can provide some detailed advice on the Civic.👍
This is a great video. I am doing a complete rebuild of 1966 International Travelall (like a suburban). I have used Lizard Skin as my primary sound layer of sound deadening and heat protection. In other projects, I have then installed Dynamat Extreme on top of the ceramic sound deadening. This car is so big I was wondering for the roof if I could install strips of a sound deadening instead of completely covering the entire roof ceramic coated with Dynamat or your product if sold in the US. Thanks~P.
Hi Peer. Have you used the Dynamat on Lizard Skin? You will find that it (or any butyl product) doesn't stick well. Lizard Skin is water based acrylic, which is porous like your residential wall paint. If you are going to do the same thing on the roof, adhesive is crucial. Therefore paint over the Lizard Skin with a solvent based automotive acrylic, which will further seal the LS and make the deadener stick far more effectively.
Yes, you can use strips throughout the roof. Look to cover the middle of the single sheet metal panels.
The Car Builders brand is looking to come over to the US. We just need to team up with the right retailers over there 👍
Good luck with your project
@@carbuilders1 cool- thanks- I usually paint it to get rid of the porousness. (if that's a word)
I've got Vauxhall/Opel Mokka (Buick Encore). I get that cost/weight cutting made this car an empty tin with thin metal all-around. Do you think that a few patches of this rubber sheet would help with overall road noise (and vibration throughout the thin sheets of steel around)?
Hi Mieczyslaw. Yes, you will achieve results by adding Stage 1 pads to single sheet metal panels and the Stage 2 Foams or Mass Loaded Vinyls will act to reduce external road noise. Good luck
Hi thete,
I can not see the "premium carpet underlay" that you presentind as third product on this video , in your website.....
Very informative! How much weight is added for a 4 door sedan?
Thank you Florin. The weight really depends on where you are going to cover and what stage 2 product (foam or vinyl weigh significantly different). The Sound Deadener is 6.5kg per box and you need two for the floor, one box for the doors and less than one for the roof. It would need two boxes of Acoustic Liner as underlay, it weighs less than 4kg in total. If you wanted the premium underlay (Mass Noise Liner Lite), you would also need two sheets and they weigh 7kg each. The second stage on the room is Insul layer and this is a foam (1.5kg). Feel free to contact us (03 8777 0960) to chat further about your install 👍
just saw this video when I'm researching to sound dampening on my car
I got a question about the 2nd stage vinyl foam
I saw different method of installing the foam , the method in this video show foam down vinyl up drop in method
But in some other video, they do the opposite site way instead , so even stick the vinyl face to the second layer and made the 3rd layer foam facing the cabin instea
So which is more functional in terms of reducing noice from out side
Bcoz in still thinking whether to get the 3rd foam layer or butyl and 2nd layer foam are enough
I saw that butyl alone eliminated alot of high pitch noise, but will it made the whole car low tone drony
Should have a link to your shop mate
Thanks mate. I will add.www.carbuilders.com.au/
That cymbal example is absolutely genius! So simple, so effective. Anyway... I am looking for help. I'd like to treat door on my Audi TT 8N (MK1) but the door speakers mount is kinda weird. The speaker is not attached to the door frame (metal) but to the door panel instead (plastic). There's a foam layer between the speaker and the metal frame of the door. The metal frame of the door itself has huge opening throughout it. How would you treat this particular door? To have better idea please check few seconds from this video: @qgIg Hope to get a reply. Thanks a lot!
Great video.
It would be great if you link the product names ?
Thank you for the feedback. We need to do this 👍All the products can be found here www.carbuilders.com.au/interior/
What would be the best product for noise reduction front my transmission? I need to put something under the boot of my shift stick. Mass noise reduction liner + something else maybe?
Hi Doobiez. The mass loaded vinyl range is best. The next thing to work out is how much tolerance or space you have under the factory carpet or vinyl. You may only be able to use a 2mm mass loaded vinyl or the thicker (8mm or 13mm) versions that have a closed cell backing foam www.carbuilders.com.au/interior/mass-loaded-vinyl/ 👍
Hello, great explenation. Sorry mayby the question is asked already. But how or were can i buy these products in my country Holland?
Hi Tonnie. We aren't currently in that part of the world, we have been delayed by covid but hopefully in Europe next year. We do ship from Australia. If you want to email sales@carbuilders.com.au what you are after with all of your shipping details we can send you a quote.
I'm redoing a NA Miata. Heat and sound deadening is a must. Hopefully it won't add to much weight.
Hi Travis. If heat is the greater issue, you can use heat shields or peel and stick peel shields to dramatically reduce heat within the car with very little additional weight.
@@carbuilders1 nice thanks
Honestly, I am not concerned about the noise. Im looking more for the insulation properties.
Should I still put on the first layer or should I just skip that?
If space allows for it, I would also add some wool insulation into the bigger gaps
Those products will work together, separately they don't. Hope that answers your question.
Oh man, now I regret coating most of the front door area in the butyl mat, the roof I have zero regrets for, since I'd rather have too much "just in case", but the doors are unnecessarily heavy now, when just couple of pieces would have probably done the trick, considering the butyl mat is just there to reduce resonance... I picked up on that when doing the trunk, placing small pieces strategically instead of covering the whole area, but at that point most of the car has already been done.
Is that mass loaded vinyl paired with a closed cell or an open cell foam?
Hi Carl. A closed cell foam
