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. 😎👍

Thanks mate. Yes, that is just one component. Good luck with your project.

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.

Thank you for the feedback 😎👍

Not really. but ok?

@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.

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.

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. 👍

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 👍

yes tyres do matters.. specially youkohama advan db

The problem is good tyres especially Performance tyres are loud.

😆 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)

Thank you for the positive feedback 🤙

Thanks Luke

“Cotton-jute carpet underlay” I had to turn captions on to figure that one out, lol

😆

Thank you for the positive feedback Michael 👍

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.

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....

Thank you 👍

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. 👍

Thanks Alex 👍

Thank you Albert 👍

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. kzfaq.info/get/bejne/qrSeoNx3tJ7Qk6s.html Good luck with the Dodge, sound like a nice ride 😎👍

You're right.

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

Those products will work together, separately they don't. Hope that answers your question.

Thank you! Cheers!

Hi mate. Yes, definitely give us a call (03 8777 0960) and we can provide some detailed advice on the Civic.👍

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/ 👍

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.

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)
