[@astanisystems]

I saw the same comment like this somewhere else lol. I put some mineral wool in my car paired with foam sheets and it helped reduce the noise. To reduce the vibrations, I used bedliner on door panels and floor, but you gotta use a lot of it to get to a good spot. I will however redo everything soon as I need to redo the wiring in my vehicle. Btw, it's a MK2 Golf

I go to bunnings and buy grunt brand flashing tape , its aluminium foil and butyl backed adhesive and costs only $8 , comes in strips about 8cm wide and about 3.5 metres long . It is really really good for the price , about 3 rolls will do doors ,parcel shelf and boot . Just tap the metal and white it sounds thin and tinny put a strip , afterwards it sounds like a solid thud . Can't beat the price or quality as its bit thicker than dynamat

[@chrispurdue5762]

Thicker doesn't mean anything. The specific formula of the butyl is the most important thing. For instance, in objective testing, Dynamat Xtreme performs significantly better than Stinger Roadkill Expert, despite Roadkill Expert being heavier, thicker, and having a thicker aluminum layer.

[@florascent9ts]

According to their website, it's bituminous flashing, not butyl. Still very effective though.

[@chrispurdue5762]

@@florascent9ts That is actually false, it is not very effective at all. I tested these kinds of flashing tapes last time I did a big run of tests with a controlled test rig and calibrated measurement microphone, and they were junk compared to even the bottom of the barrel sound deadening specific products (ignoring fatmat, which is just rebranded flashing tape). Not to mention flashing tape has poor heat resistance due to its bitumen content. Let me put this another way. Peel and Seal, a similar flashing tape, reduced the amplitude of the resonance on the test panel by less than 1 decibel, with 28.5% coverage of the panel. Dynamat Xtreme reduced the amplitude of the resonance on the test panel by 11 decibels, at that same 28.5% coverage.

Vans are horrible to start with as they actually amplify noise. Any noise coming from a bad differential will sound like live grunge band. All Diesel engine use the heat of compression to ignite diesel fuel so there are no additives for that. The bad news is it’s huge, takes a ton of material and if finish and not a bare bone work truck, you will spend hours removing plastic panels and break fasteners. Do it when it’s warm as clips will break real easy when cold. Sorry! ASE Master Tech since 1978 - Retired

[@allicks9220]

I have successfully removed a LOT of drone noise and NVH (noise, vibration and harshness) from my car after doing four things that made a big difference. (And I had like everyone else started off by trying to get things quiet using butyl mats/dynamat etc. I realised that that had a very limited effect and beginners usually end up sticking down way too much of the stuff and later regret it because you start thinking how much you’ve weighed the car down by. And a year or three down the line you end up taking two thirds of it back out - or trying to). Here in England I run a 2011 Ford Mondeo (Fusion) estate/station wagon. MY FOUR BIG TIPS for INSTANTLY reducing noise (REMEMBER - you are NOT going to get your sub-$25thousand dollar car to hush like a Bentley. BUT - you can get a LONG way towards it.) NUMBER ONE - REPLACE YOUR TYRES. If you want quiet, you need to LIFT the car further away from the ground and have less tyre in contact with the ground. So run NARROWER tyres with a TALLER SIDE WALL and if you can a SMALLER RIM SIZE. I replaced my 215 55 R17 tyres with 205 65 R16 tyres on replaced 16 inch rims. This dramatically reduced the rolling drone of the tyres on the road and gave a softer ride because the taller side wall raised the car further above the ground as well as reducing the contact with the ground. Yes you will get less of a sporty ride but I’m not interested in a sporty ride. NUMBER TWO - INSERT SURGICAL TUBING into all your door seals. You need to improve resistance to outside sounds coming in. Adding surgical tubing into all your door seals makes them nice and snug. Don’t go TOO tight though - get the right tube width - or else you won’t be able to shut the doors and you’ll feel real dumb. NUMBER THREE - Buy cheap ‘RECON FOAM’ cut it up into small cubes and shove it compacted into all the empty cavities under the trim around the console, footwells and glove compartment. You wouldn’t believe how many just open holes there are in that area doing nothing but causing sound from the engine and up from the ground to reverberate around. Foam (NEVER USE SPRAY FOAM - it will enter places you really don’t want it to get and you will never get it out in the event of a repair requirement) dampens all that NVH and contributes to the multi-pronged solution we are going for. You need to do a LOT of things to add up to removing those decibels. NUMBER FOUR - Go to the back of the car. On most cars under the rear bumper on the left and right corner areas hidden away you will find a one-way ventilation flap on each side of the car. These are interior pressure flaps that allow air to escape from the car when the doors are closed and to allow ‘used’ air to escape from the cabin as new air enters from the front air vents. BUT they usually are located behind a very large cavity that sits adjacent to the rear wheel arches. In some cars you can reach into this large empty cavity through the back hole at the rear of the small felt door/closet you find in the left or right wall of the boot/trunk - the little hidden hole you might put an emergency traffic cone or yellow jacket in for example. I discovered these cavities causes a LOT of droning noise. The noise from the rear wheel comes straight through them, reverberates and comes out through the interior rear air escape vents. FILL ONE OF THESE CAVITIES UP! Don’t fill both - you need one to maintain the ability to release the cabin air pressure remember - and often the fuel fill area prevents access to one of the cavities depending on if you have a left or right hand drive. But if you can get access to one side - fill it up tight with old rags, recon foam, old carpet that can be scrunched up - you want as much as possible to remove cavity space that creates reverb. Use anything not too heavy but DENSE. So recon foam, being more dense, is a lot better at dampening and muffling drone than, say, bubble wrap. Pack it in tight - and there’s room for a LOT of foam and rags in there. The more you stuff in the quieter you'll get. This for me REMOVED 80 to 90% of the heavy drone in the back of the car - which had been particularly irksome on long motorway journeys. NUMBER FOUR POINT ONE (!) Not essential but this improved my car dramatically - If your car is one of those that tilts down slightly towards the front end (to allow for the backend to dip slightly and the car to even out when the trunk is fully loaded) buy a pair of polyurethane lifting spacers to sit at the top of your front struts. Your garage can fit them for about $250. They again move the front end higher off the ground, away from the noise of the road. So coupled with the tyres we’re really changing how close we are to the noise of the road. Plus they make the car sit more evenly and look a lot better... SO These are my main tips for really getting to a quieter, pleasant drive. And they have really worked for me. I wish you all the best with your own particular car - every one has its quirks and every one will have slightly different solutions. It's a lot of sometimes unpleasant work, but persevere and you can get a nice result.

[@Andrew-vx2ls]

Very good tips. Most of these are also light and reversible (unlike the awfully expensive and heavy Dynamat which is a complete no-no).

[@matmichalke5734]

I use killmat, they have 2 thickness available and the thicker is a bit better and I have had really good results and I use it because I add amps and subwoofers to my car which create vibration

[@joshm340]

One thing that I've noticed making a big difference is getting the windows tinted. I'm guessing the film helps to decrease vibrations coming through the glass.

[@greenlighter6048]

I would have never in a million years imagine that

[@Ashx292]

I can’t tell if your joking or not but the material used to tint your windows is incredibly thin, there’s almost no way it could dampen or reduce any sound unless you can somehow hear sunlight. That’s like saying wearing sunglasses makes the world a bit quieter for you.

[@vipercrazy9910]

The inner seal for the glass on the bottom can get worn with age and window tint will seal up the gap again causing the air movement from the speaker to seal inside the door better.

[@robertprice9052]

The most underrated soundproofing material is spray foam insulation. I have used good stuff and DAP foam insulation inside body panels to cut down sound transfer. This works well in pillars, and wheel well areas. The foam will pernitrates into areas you cannot put peal and stick sound deadeners. In the cargo area of vehicles there are a lot of tight spaces where foam works well. I would also begin with a spray on undercoat. Most of the road noise will come from the wheels on the road and the exhaust drone along with wind noise under the car.

[@michaelsoutdoorlife]

The main thing to remember when sound deadening and sound proofing your vehicle is using more than type of material. For instance you need to use the foil backed products but also should use a similar sheet product with acoustical foam. Then you should focus on how its installed, meaning taping the seams and pressing the mats forcefully with rollers to promote adhesion and proper noise cancelation. And don't fall for name recognition you will overpay for that name, there is so many products that are the same or better than those big names at a way more affordable price. Trust that you will need lots of material to properly complete the installation process and saving money because of a name on a box will help make the process more affordable and make sure you get the results you expect.

[@JohnDoe-us1ek]

There’s a dedicated group on Facebook that does actual tests on deadening products. Dynamat actually ranks among the best out of all the products. If you think Noico and Kilmat are as good as Dynamat or ResoNix etc then maybe you ought to have a look at their tests yourself. As far as MLV & CCF products, your comment applies.

Dr. Detroit Metal treatment is one of the best products to reduce the noise from the engine. Been using it for 30 years

[@deankay4434]

Be warned that using anything in the doors will eventually hold water and accelerate rusting. Even many spray-on products get hard, crack and cause rust as well. Never used the shredded cloth type materials as they work like sponges under wet or snow covered feet on floors or inside doors. Where the glass meets the paint, if the glass moves, that is a belt mounding and are designed with a felt like material. If worn or missing, the moving window will stick bad or stop moving. These cannot seal water out completely. This is true with most floors when snow melts. Under the rocker panels and doors, you will find drain holes spaced across the panel. Without them or plugged up with debris from leaves from trees, the panel will hold water. It is the same at the backside lower section of the front fenders behind the plastic panels. In front of the windshield is a high pressure area for air while driving. It is funneled into the cabin of most vehicle when fresh air or mix is selected. Fine, but leaves, tree seeds and other material get in there and if not plugging up drainage paths, then this material collects, holds moisture and rust out the cabin corner and back side of fenders. I had a single customer who complained or water-like noise and ground the drain holes where plugged on the passengers door that was never used. It had about 30 gallons of water inside the door and drained for an hour after cleaning with small hook and compressed air to get the materials out. Hope this helps.

[@deankay4434]

Well, anything you do beyond the factory will help. “Kilmatt” I think is cheaper than most, put that on the floor and up the bulk head (Called Fire Wall by some who have thermal events) Double up over the exhaust unless you are going for duals someday. Inside the door bothers me the most, I will explain. The skin is folded over the door frame, spot welded and seam sealer apply. It get wet inside and leaves and just get in there. First, check the drain holes, blow compressed air to open. If you take the door panel off, you will find plastic water shield. (Hum, water shield) it protects wires, switches and speakers. The bottom corner to the center need vacuumed out. Those corners get no protect other that a factory dipping. Buy a yellow waxy spray-in type rust proofing. Describe it just like that. It will make door corners last 10 years longer. Same under hood at the front, rear and sides in that order. Lay plastic garbage sacks turned inside out so you can use them, to catch drips. Open trunk and pull back carpet near inner wheel arch. Do the gas cap side more because it is tricky. Spray where inner and outer meet. Gravity will help on warm days to run product completely into the corners. Gas cap sides are bad. They have a pocket for the filler neck, lid, inner metal tube for vent. (Please note; This is rust proofing while controlling sound. What is worse? A quit car or a quit car with rust along the bottom everywhere?) Materials are better but made like shingles on your roof, asphalt and butyl rubber. A laminate roller from home improvement store works great. If you can change bulbs and disconnect electrical connectors, wear rubber / latex gloves but while at home store, but a tube of dielectric grease. Apply like 1/2 tooth paste onto/into connectors or bulb sockets as this keeps water out and moisture from the air. Weather-Pack connectors are common but not perfect. Use on spark plug tips and batteries used in car, flash-light, bulbs. (Note; Do not get on headlamps bulbs or oils from skin. Clean with isopropyl if needed) I have seen spray-on rubberized super-supper-Heavy-Duty spray get hard, crack, hold water and cause rust fast but is quieter. Put on inside. Clean out vents in front of windshield as this debris ends up in the bottom of both front fenders until rust or small tree shows. Clean out by turning wheels and remove bottom fasteners (All kinds, pull-out rivet type, screws, plastic & metal) but pull out bottom 4-6” if plastic and clean with air, garden hose anything will help. Yes, sound proof clean floor, wipe with isopropyl or wire brush. If you are outside and have respirator, acetone works good as it dries very fast with no lingering oder, or outgassing. Both are flammable while being careful, disconnect negative battery cable. If your vehicle is close to 20 years old or more, you may have to reset the clock and pre-set radio stations. It will NOT clear codes set by engine or turn speedo to zero. Cut to fit the frame of the door where the plastic water shield goes. A hair dryer will help remove the plastic from rubber adhesive that is to be reused. Packing tape will hold it in place or if torn during service. Keep rust proofing off internal door locks & latches. Use an oil can dispenser to place a few drops on these parts. To keep doors from freezing to rubber seals (Found in Owners Manual) but purchase silicone paste in cans that have brush applicators and spread along lightly, spread with fingers as to coat the seal. Gently wipe off excessive silicone grease if applied too thick. This hydrates the seals and makes them last longer and never have a frozen door in the winter again. Hope this helps, a little long, but 38+ years of fixing cars teach you what works! ASE Master Tech-1978-Retired

Large roof on a '48 Ponty can get pretty scorching in July at a car show and in the winter an unheated garage can get below-10- A plastic or board type headliner may not show a loose deadener or loose heat shield--- but a cloth one would.-- another site claims only Xmat won't come loose and will stay in place with high heat.

The spray on they mention @6:45 works best for your application. That specific product Spectrum, from SecondSkin has a heat rating of 400F. That is mainly for soundproofing though, they also have a product specifically designed for thermal insulation, called Firewall Ceramic Thermal Coating, and it goes on, and feels afterward, much the same way those spray on truck bedliners do; so a much more natural oem feel to it than a bunch of sheets of butyl baking up the place.

[@TIMEtoRIDE900]

If you have a cloth headliner you could try cutting up some windshield sun blockers. They are aluminized bubble-wrap - very light weight. Use spray contact cement like headliner spray, which is designed for car heat. Also use Dynamat, but do the 1/3 rd trick instead of full coverage, you put it in the center of the roof areas.

[@tk421tt]

Soundproofing =/= sound damping. Most products in this review are damping materials and help reduce panel rattling by adding weight. This reduces the resonant frequency of the panel. They do block a small amount of noise but the material used by car manufacturers to block noise is MLV (mass loaded vinyl). It’s a thick heavy rubbery material which is typically dark grey or black. You can see it under your car’s carpet especially in the footwell area on the firewall. There are a couple sound proofing car companies that sells it. I’ve used it in a few vehicles and the results are great. Use the dampening in this video to cover 25% of your panels and then cover the areas with MLV. Your car will be much quieter.

I want to see someone experimenting with different cheap sound deadening stuff for cars - on an outdoor mini split unit (air con). I expect it could help. When I first switched mine on it made an awful racket because a component was touching the side of the case, I shoved some foam in between it and the case.

[@soundproofguide]

That’s a great idea. I’m going to make a video of just that this year at some point. I’ll probably use the Amazon basics sound deadening material.

@@soundproofguide They make "Compressor Sound Covers/Blankets" but I've only seen ones for the big American types, not the smaller rectangular types. I'm sure if you could get one of those (or same material) on the compressor that would defo help. I need to take the front panel off to see what's going on in there. There may be room to put one of the jackets on the compressor, and maybe stick some sound deadening material on the insides of the case.

Hi, if i put sound deadening material inside the door panel, does the rain water affect the performance of the material? Is the adhesive going to be affected? Thanks

People do that. The glue is pretty strong once it sets though and the material is rubber so it should be waterproof.

the 315 mil is closed cell foam for use over butyl rubber. The closed cell foam is not as effective in reducing vehicle vibrations as butyl because it’s for absorbing sound but not dampening.

[@chrisbooge2217]

There are several problems with this video. First at least four of your ten sound proofing products are just different manufacturers of the same aluminum backed butyl sheets. Second you listed flex seal as a sound dampening material its a realy sticky tape but not a sound dampening material. Three you repeatedly said that aluminum backed butyl sheets reduce sound levels in a car it does not (buy a db meter test it for your self) it does dampen the vibrations of the sheet metal helping to lower its resonance frequency down to an inaudible frequency as well as reduced the transfer of vibrations. But bang for your buck its not going to be your first choice to lower the ambient sound level in your car. Mass loaded vinyl is a good choice, high density foam is a decent choice. You mentioned using wool carpet pad and thats a good choice and is a product already used by auto manufacturers its called jute carpet padding and can be found at upholstery supply stores or Amazon.

[@nebo23]

Thanks! great content!

[@Sensecommon557]

the shit aint rocket science boys adding almost anything will help thin noisy sheetmetal.

[@burnpitcav1519]

If you want to kill sound you must have 8 mil minimum but 10 plus mil is recommended. Also, you only want butyl rubber on the floor and foam in the doors/dash/headliner. Foam cell sound deadening is far superior at stopping sound but is less durable. Soooo in the large air cavity’s you want lots of foam. My car has 18 mil of foam in the center of each door tapering out 10 mil. You want to get into the door cavity inside of both panels as well as interior facing panel and behind your Trim. I promise you that more expensive means nothing. Siless brand off Amazon is perfect. What matters most is understanding how sound is transferred in air cavity’s and through material. Also, I have 10 large puck magnets from harbor freight located through out to cut down even more.

it depends on how thick it is, and where it's placed between you and your ac

[@DataLog]

AC installers often do the job too quickly and don't put rubber dampeners on the bolts. It's a $10-20 part that must be installed to reduce vibration. Check if you have them. It's about 2-3cm thick rubber between the bolt and the AC.

In 2008 they couldn't even be bothered to add a decent radio, but now they're cutting edge etc...
