Top 10 Car Soundproofing Products That Actually Work! DIY

Just crank up the stereo volume up.

Which one you think would be the best one?

Anyone actually made a Jeep gladiator sound proof

A question for you guys or anyone who knows about this stuff, my new car makes a booming low frequency noise (like a subwoofer) when driving over cracks and rough surfaces, and I have noticed that the noise appears only when the rear tires hit the road imperfection, the front is fine. What is causing that, it is a new hatchback car, the service says its normal but the noise is too much. What needs to be soundproofed in the rear to make it better? I did only the trunk floor so far , nothing changed.

I really enjoyed the mentioning of temperature control being important and a second later the little kid is being held hostage in the car and it shows how much the little tyke is enjoying the moment!

Also, I want to mention the oil changing in the first few minutes of this video. I can’t remember another sound deadening video that includes this priceless moment of real and effective means to make every possible effort to keep the cars external sounds to a minimum. Bravo!

And using as much of the product as the manufacturer was able to produce in a full shift, that assured that the company would continue to grow into the next fiscal quarter!

I can imagine Kidnappers be watching this for Vans

Pretty informative video and well edited, i have a Kia K8 which already have pretty good sound insulation but it has 19 inch wheels with low profile tires, what is the best solution to reduce or remove floor vibrations?

Butyl rubber vs asphalt based which ones the best one for car deadening material?

What about the sound dampening qualities of KBS INDUSTRIAL RUBBERIZED UNDERCOATING and RUST-OLEUM PROFESSIONAL RUBBERIZED UNDERCOATING???

And Besides the cell Foam, like other Honeycomb Foams, other Foam insulations?

could i use engine insulation liner for indoor soundproofing? i have some extra in hand, but i'm not sure if it's recommendable.

Would a butyl deadener like dynamat work well over bedliner for rust protection and sound insulation

Just a gentle correction: using the word “proofing” would be incorrect here. Noise/sound control/reduction would be appropriate. “Sound proofing” a car would be an incredible feat

Not POSSIBLE. A reduction of 50% is incredible IN A VAN and will WIN AWARDS at SEMA auto sound contests. The BEST on RECORD was a 66% (33 dB) reduction in noise level IN A MOTORCOACH so where's your Guinness Million Pound Prize and plaque??? Oh, same place THRUST's World Record for Breaking the Sound on Land! IT DIDN'T HAPPEN!!!

Why are so few people talking about noise inside the car when you drive?? It is also an important thing when it comes to driving comfort!

Many car factories are very lazy in this area and do a very poor job.
MUCH easier to get a car that is too noisy than it is to get a quiet car!

Some examples.

1. passat 1998 1.6l sedan manual transmission. very quiet car while driving.

2. Ford Mondeo Titanium CC. 2012, too much noise inside while driving.

3. Subaru Forester 2006. Very noisy when driving!

4. volvo xc70 2011. too noisy inside and too much tire noise no matter which tires you used. Not the worst but not good either . This is not a wv polo but a volvo xc70.

I think one of the most impactful thing you can do to reduce the noise is changing all the windows into laminated glass and use double rubber insulation on door crevices.

Isn't there any material you can install on top of the carpet but below the mat? Like it doesn't have to be adhesive, just absorb sound

Thanks for the review, be good and may you live long and Prosper!!!

Here are some to add to your list.

Acoustiblok Blok16 and Blok32 sound isolation material. Use to soundproofing recording studios, buildings and car, or whatever.

Lizardskin spray with Sound Control and/or Ceramic Insulation.

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.

I think second skin still the best out there

Why was there footage of an oil change? 😂 Need it to be quiet so that the driver wont be able to hear the work being done at a quick oil change shop?

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.

Best video yet

Thanks

Can i put it on the engine?
I don't think it'll over heat since it has a radiator.

do you think studio sound proof would work better?

‘

Tires can be a significent noise generator.

People spend thousands to the reduce weight of their car, how’s much do these solutions weigh?

There is only one way to sound proof an Idaho truck. Don't start it.

To reduce the most noise, don't let your mother in law in the car. 😂😂😂

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.

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.

Oh, I usually don’t let tire noise bother me. But if I go on a long ride, I use a pair of orange earplugs that I get from Home Depot for construction sites, that’s right for five cents. I could have the quietest car in the world. I definitely use it when I go from New York to Carolina.

Wich one beter and cheap?

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.

So, what about eliminating the sources of the noise? For instance, your tires, exhaust, wind under and around the vehicle? Did you create those noises for others but don't want to have to live with them yourself?

ResoNix is the best of the best.

Your list is ok but not the best.

I use floor underlayment

$159 AirPods Pro, noise cancellation works but not quite safe sometimes.

What is the best heat and shield absorber for vans where engine is under the driver's seat?

lol I’m on my another account😊😊😊

Can any of nowadays construction spray foams be used on car's noise cancelation? How's the sound proofing ability 😮😊 just curious about the possibility as it looks pretty light.

Please how to clean the car and remove grease to stick the sound deadening so it would stick perfectly! 🙏
Please a DIY because I live in Africa (Ivory Coast) 🙏🙏🙏

What works best for the trunk so you can’t hear anyone screaming? 🆘🤫

Foil is toxic unfortunately

Lightweight mats are pretty useless.

Great Video! Thank you 🔥👏💪🫶

When i was a youth i worked in a paintshop where we offered an undersealing service. This involved spraying the whole of the underside of the vehicle at low pressure with a heavy coating of a rubbery material. It made a big difference to the cabin noise.

I noted only 9 products; not 10. Could you print a list for copy? Thanks! Very resourceful/useful to vehicle owner.
