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. 😎👍

​@@carbuilders1 And if you want better insulation as well as sound deadening (like me), then covering everything makes more sense, right? 🤔

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

[@darrowfortheprosecution1404]

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.

[@Moriggia]

@@89andresp how is going? How much weight did you add? Is it worth? Thank you 😁

[@89andresp]

@@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.

[@peterdarr383]

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. 👍

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.

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.

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 👍

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

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.

[@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 👍

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

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

[@Evoandrs]

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.

Been looking for this sort of Information for ages! Subscribed :) any chance your sound deadening is lighter than most stock ones?

[@carbuilders1]

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.

Do you install certain sections in every panel? or do you have to cover entire car with this? With your cymbal example you applied a small patch and it killed the vibration....
