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....!

[@carbuilders1]

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. 😎👍

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.

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.

[@carbuilders1]

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. 👍

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

How about just driving the car and taking decibel measurements before and after applying the insulation material?

[@chrispurdue5762]

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.

[@gymkhanadog]

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.

[@chrispurdue5762]

@@gymkhanadog Taking short measurements before and after are misleading. Too many variables. Just a difference in temp changes air density and therefore noise levels.

[@gymkhanadog]

@@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.

[@chrispurdue5762]

@@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.

@@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.

that cymbal trick btw, you will get similar effect with any random blanket

[@Chris.Davies]

You failed to communicate the most important thing in sound insulation in a car: THE RULE OF 25%! This means that if you have covered 25% of a panel in your sound deadening material (whatever it may be) then you have done 95% of all the sound deadening you can ever do to that panel. Covering the other 75% is pointless, as all it does is add weight, and huge cost and inconvenience. The Rule of 25% is a godsend to motorists, and a "bunch of bullshit" if you happen to be in the game of selling sound deadening, or installing it professionally. :P

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.

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?

[@carbuilders1]

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 👍

My car should be so loud that you have to shout, no muffler no cats just straight pipe exhaust coming out under the doors. The V8 should literally shake the cabin apart and the AC should be totally broken so that you have to open the quarter panels to get some air but then the engine sound will overwhelm you if you open them. Thats my idea of a perfect mans car, also it should be 50 years old. Not some last years air conditioned model plastic bucket with heated seats and gadgets and 1.5 liter hybrid. That is a womens car.

[@AsAngelsFall221]

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.

[@carbuilders1]

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. 👍

[@gymkhanadog]

Does your foam product have a mold inhibitor like some of your competitors? I don't see that listed on the website. It's nice that there's a closed-cell topper, but unless you intend to blanket your entire vehicle and seal every little seam and joint, moisture will still get down into the open-cell underlayment and mold. It may not rot the material like jute, but it will mold. What happens if you have a leak inside the vehicle? What happens if you spill a realistic amount of drink, as in, an entire cup of it (12-24oz)? It's going to soak through your carpet and the first seam in the insulation it it finds it's going to seep down through capillary action. Just because it isn't jute doesn't mean it can't or won't mold. This is still a very real concern for modern insulation.

[@Set_your_handle77]

Any danger of moisture getting trapped when placing the materials down? Or am I overthinking it?...

[@carbuilders1]

No, good question. The butyl facing the metal on the stage 1 sound deadening mats is water proof. We have a video where we pour liquid into a pocket of sound deadener to illustrate this. This type of material is used in plumbing applications to create water proof seals. It is important that you rust-treat the surface before applying the mats and that you roll the mats down without leaving air pockets. The sound deadener will act as a rust barrier. Around the mats you may still want to treat the metal with an anti-rust wax. Please free to call us to discuss further 03 8777 0960 👍

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/ 👍

Great 👍

[@carbuilders1]

Thank you! Cheers!

Seems like a good product, but your leaving money on the table by not adding links in the description to direct people to your website or a credible site like Amazon.

[@carbuilders1]

Thank you for the feedback

Don't radiant barriers require an air gap? If you're putting a radiant barrier in contact with with the material, it's just going to conduct heat from one surface to the next.

Hi Samm. Your right, we don't recommend the sound deadening to be used as a heat shield, its purpose is to stop vibration generated noise. We have videos on heat shield products that are heat facing. 👍

When i close my car doors they make a terrible bong noise, its sounds so cheep, whats best type of insulation to stop the bong? Thanks

[@jeanchardonnay5627]

Hi thete, I can not see the "premium carpet underlay" that you presentind as third product on this video , in your website.....

[@simonw2631]

Great video ! Now i need to find the same or similar stuff in europe. Cause i’m not gonna ship sound deadener from fucking australia thats insane 😂

[@Mietas2]

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)?

[@carbuilders1]

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

[@univerz0]

What would you use for a dash that rattles on bumpy roads? The most distracting noise in my car seems to come from the glove box door rattling.

[@mhaas281]

I used Weather Strip window seal on my car for that. Seems to work well. Just run it along the few key areas to reduce vibration.

[@thomshere]

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!

[@carbuilders1]

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. kzbin.info/www/bejne/qn_Rnqx8hJ2fmdk Good luck with the Dodge, sound like a nice ride 😎👍

[@Maid3n]

So how many rolls do you think I’d need for a Datsun Wagon? I’m too lazy to measure the car.

[@carbuilders1]

Hey Keks. Did you want just stage 1 deadener or underlay too (stage 2). If you give us a call 03 8777 0960, we can give you all the answers (even if you don't measure up 😆 ) 👍

[@gregmakridis]

I have a question about which exeact product to use in my case. So i have removed the sound deadening of my gear selector since i replaced it for a bigger one but the oem one does no fit. What do you recommend?

[@carbuilders1]

Hi Greg. Please send this question with a photo to [e-mail] so that we can best advise 👍

[@aph1555]

Do you install as well?

[@carbuilders1]

Hi ap h. Yes, we also do installs. Feel free to call us to discuss 👍

[@alexl2174]

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.

[@carbuilders1]

Thanks Alex 👍

[@artman102]

I'm thinking about filling fender cavities with expanding foam. What do you think?

[@MrCareerplanning]

Just wondering if the car ever had a dent on the door and someone used a welded nail gun to pull the dent, will the sound deadener catch on fire?

[@carbuilders1]

Hi Ramiro. No, but you will destroy the product.

[@superdupertrooper6732]

Damnit I thought this was Hondaprojason still watched tho

[@carbuilders1]

Haha.. thanks for the watch 👍

[@rovercoupe7104]

Where would one get the best results from the least amount of sound deadening? In the doors? M.

[@carbuilders1]

This is a difficult one to answer as it depends on various factors such as the make, year, existing deadening, environment (off road) etc however the deadening will have the best results when it is applied to large, single-skinned, sheet metal areas particularly where mechanical noise is found. For Stage 1 vibration noise, the dampening sheets do get great results in the doors however, if you are trying to cut down on external noise by using a Stage 2 product (sound blanket) then locating the source of the noise e.g. firewall, engine noise, will get the best result. Sorry for the vague answer as it really depends on what you are trying to achieve/purpose ( e.g. off-road) and the vehicle.

[@rovercoupe7104]

Thank you. Your reply was very helpful. M.

[@wazid0122]

lookin for a video like this for a long time especially on what to do to get rid of heat comin into the car

[@carbuilders1]

Hi firefox01 Glad that you have found the information you have been looking for here 😎👍

[@sergiodoordie319]

It's good but puts more weight to the car right

[@carbuilders1]

Hi Sergio. Yes, it will. If you do 4 doors it will be 6kg but even our large 4x4 vehicle packs covering all areas of the vehicle in Stage 1 and 2 will only add a teenager passenger in weight

[@jdigitalseven7]

As an American I have no concept of what 4 kg/sq m is 😂😂😂😂😂

[@carbuilders1]

😆8.8 pounds 👍

[@im_Spade_]

Love your accent my friend

[@carbuilders1]

😆😆😎👍

[@washout04]

I'm getting this. The road noise on coarse chipseal in Australia is so bad.

[@donealable]

Wish you would link some of those products.

[@carbuilders1]

Sorry, we need to start adding this to our videos. You can find these products at www.carbuilders.com.au 👍
