Sound Deadening

Close to half the vibration damping/noise mitigation threads on other forums are debates about using asphalt based materials as a vibration damper. I’ve spent way too much time during the last 5 years typing and re-typing responses to these questions. Let’s keep it in one place to reduce litter and redundancy. This topic was my introduction to aftermarket “sound deadening”. I had a noisy car, wanted to quiet it down and started to do research. This was 2005. Several respected “authorities” were vocal advocates for asphalt. Part of this came from the belief that products like Dynamat Xtreme were part of a conspiracy to fleece consumers. Part of it was the often repeated “f…

I spoke with Don of SDS and we thought this would be a nice addition. As we have a dedicated Sound Deadening section here, this topic is meant for technical questions you want to ask Don directly to help add to the resource of this section. No, this is not a topic about SDS product pricing and such, that is what Don's email is for. Hopefully this will be a nice focused discussion to help people understand the concepts and purpose behind different materials and products available.

If the stuff comes on a roll is that a dead give away that it's asphalt based? Recently a new player has come on the market claiming butyl based sound deadener. Audio Technix is the place. Their claim is a 60mil thick sound deadener / 4mil aluminum with butyl adhesive, Their introductory offer seems good, but their stuff comes on a roll. Should I stay away? Thanks.

I've always just wonderd this, what would happen, or what effect would it have to put sound deadening or Mass Loaded Vinyl inside of your box? I know it sounds stupid, but just curious I guess lol

I am going to be tearing up my car for a wall build and I want to sound deaden as well. What material can I use so I have similar effects as MLV (Mass Loaded Vinyl)? Basically I will be looking for a heavy, flexible material, that is on sheets and does not smell awful. I'll be going through our big shops for construction and whatnot, but you guys can suggest other things and places I can look into.

So being on a budget I was looking for some affordable options for sound deadener. I found these: JC Whitney (Yes! JC Whitney) here: http://www.jcwhitney.com/ultra-silver-vibration-damping-floor/dash-kit/p2020613.jcwx?filterid=c2663j5 JC actually has quite a few variations. And bonus if I order before tomorrow night I have a 20% off coupon. Eastwood: http://www.eastwood.com/eastwood-thermocoustic-material.html And also b-quiet.com Does anyone have any info on these products? Any good? The Ultimate stuff from b-quiet looks promising. In my current install I tried using the asphalt roof repair stuff with the aluminum backing from Lowes but it didn't seem to work all that w…

It worked for a short period of time. Really Nice. I had two layer on entire trunk lid. but as far as adhesive, its horrible. So would I recommend it?? HELLLLL NOOO lol I now have DynaMat Extreme sitting in my room. Here's a couple pictures of it falling off, it was worse than this, i pushed it back up though.

Is peel and seal a good alternative to dynamat or any other name brand sound deadener? It comes in 6"x25" rolls for less than 20$.

Hey guys. I'm looking to deaden my Jeep Cherokee the right way. But just like anyone else, I still want a quality product for a good price. I have heard tons of good things about quality and price of Second Skin, But I also found this site: http://www.sounddeadenershowdown.com/products/cld very useful. I Understand the fundamentals of sound deadening and only want to do this one time with the greatest results possible. Please no arguing about asphalt or using low quality products or any of that other stuff they do on lame forums. My questions: 1. According to Sound Deadener Showdown, more than 25% coverage is a waste. I don't want to waste anything whether is be t…

Okay so for those of you who don't know what vehicle I have, It's a 1997 2door jeep wrangler hardtop. The hardtop is made of polycarbonate, plastic, something you get the idea. So it flexes a good bit and wanted to hear what you guys would suggest for fixing it. Would cld tiles soak up some of the flex? just trying to brace the plastic so my sound output isn't wasted Heres some pics:

Sweet build going on in Corona, CA using Second Skin sound and heat insulation to give the driver some relief from that HUGE engine on his back. Damplifier Pro (CLD) to kill the vibration and Luxury Liner Pro (MLV) to help tame down some of that engine noise and thermally insulate. Can you guess what vehicle is being built here?

any one tried it i just did the whole trunk,the back quarter panels and the rear seats.didnt want to do the floor because i got too lazy sound deadening is a b,paid $160 with shipping for 100 sq ft. 80 mil has any one had any bad experiences if i have a problem im gonna guess its when it gets hot as hell and the asphalt gets soft but night and day diffrence in bass so much cleaner and deeper i havent done the roof yet if i do that will i notice i diffrence in bass or no??

So after installing my Cs60CF, I could not believe how bad the woofers sound It sounds as if they were distorting, and thats with all EQs off, no bass boost or anything. So I talked to denim and we concluded it could be the doors. They are not deadened. I just replaced factory speakers and place the new ones (i know, i know, but i didnt think it was gonna sound this bad). So I came to the conclusion that to enjoy my midbass and not have to lower the 125hz band to -3, I need to (just learned this) seal the doors. Seriously, my midbass is dead cause I cant rise the volume or else the woofers will start to sound nasty, kinda distorted. Even with EQ on flat. I always have to …

Just seeing if I'm the only one who would love to have Don (SDS) have his own dedicated forum.

Trying to get some ideas on how much I need to complete my Mercedes C230 coupe. If I have a lil bit extra left over that is ok too. I have two other cars that could use some. I wanted to use spectrum instead of CLD but I'm kinda worried about the over spray. Kinda why I was leaning towards the sludge instead which can be applied with a brush. I've seen a few vids that show it isn't that much but I would need to completely tape off my dash and all the windows for the spray. Plus i have quite a few plastic parts inside that spectrum wont adhere to. I also had thot about using luxury liner pro instead of buying the MLV/CCF seperate but it was cheaper this way. Th…

has anyone ever used rattle trap from flatmat is it anygood and if so how does it compare to dynamat and damplifier

So I'm a complete newbie when it comes to sound deadening. I know of the materials used and such after reading on SDS and such years ago. I was recommended to just use CLD tiles when I queired don years ago, but as far as the process of applying it and using it properly I'm not very knowledgeable and have no experience. I've been running my SSD 18 for almost 4 years now without any sound deadening. However, I'm looking for the cheapest solution to my problem. My system is in my signature. I just added the two new amps to my build, and my sub is receiving a lot more power. More power = louder = more rattles. It's very unfortunate, and my cars an 89' so it's pretty easy t…

I am very interested in this topic and after a google search I kept being redirected here, so i signed up. i read don's forst pinned post ashphalt vs sound deadener. i must say my opinion was the same as the examples "well it worked good till it fell off on the second hot day" and i was "that guy" saying stuff like "hey you can get that stuff from home depot" well i am willing to conceed and try a different aproach for this new project. my vehicle is a commercial truck, a 5 ton like a moving truck you probably see making deliveries in your city. i have no hood, it is a tilt cab so i sit directly overtop the engine and cooling fan. after a HP upgrade and a 2nd turbo charge…

I will be gettin 50sq ft of deadner, I have a 2000gmc sierra ext cab. How much would that do me for? Has anyone ever deadened this body style? I will be doing the roof, back wall, and floor. Also the doors if I have any left over.

Anyone tried this stuff? I probably should have asked before using it, but just curious if anyone else has and hearing opinions on it. I feel like its worked to some extent, but I also still have a fair amount of rattles. I know i need more of it to place on my inner panels, but my main focus has been on the trunk area. http://www.thermotec.com/products/14600-suppressor-acoustical-heat-control-mat.html http://www.amazon.com/gp/product/B004PILLZG/ref=oh_details_o01_s00_i00?ie=UTF8&psc=1

See alot of people using this product.. its cheaper than second skin.. how does it perform compared to second skin? Im considering deadening my tahoe so ill need alot... this stuff just seems cheap lol... but what do I know im just goin off pictures. anybody use it that can give me some sort of review? appreciate any help.

Well on the hunt for sound damping material I came across a ton of manufactures and I am not sure which ones are good these days. Please let me know who makes a good one. Dynamat Hushmat Rockford Fosgate [not sure if they still make their own] Second Skin Stinger Roadkill That is the only ones I heard of. Thank you.

Good morning ladies! I just wanted to inform you that I am now a proud owner of B-Stock CLD Tiles straight from Don @ SDS.... I skipped using the forum since I had some random questions for him... (a/s/l) kind of stuff... Not really? Anyway, so I ordered a bunch and if all goes well I will be not only doing my 2003 Camry but the lady's 2010 Honda as well... Give it some quietness... I will post some pictures when I receive my packages.. Another thing I'd like to mention, Don is awesome... Mentioned my license plate problems on the trunk lid and he immediately got back to me and offered a sample CCF for the plate to create a barrier between the two metals... What an amazi…

Hey all, i just bought a shop pack of damplifier pro 80ft, hoping it will be well worth it since it cost me around 540$ for the pack (shipping/us-cad). I just wanted to know if i should deaden the whole car which would require prob another 80ft and im also thinking of ordering a pack of mlv/ccf. I will be running around 1200rms, and the car is a lexus so it is pretty quiet from start. What do u guys think? Im thinkin if i need another 80ft will jus go with regular damplifer instead of the pro to save some $. Also, getting it installed is another huge cost. Theres this shop that i know do an amazing job 100% of the time but they are charging around 1000$. Another shop whi…

Sup, My sunroof is clapping pretty bad with my current setup and I'm planning on doubling it, so I wanted to know if anyone has been relatively successful controlling sunroof clap. I only have problems when giving demos and competing, since I don't bump it (full tilt) on the daily. I use my sunroof, so I have no plans to glue it shut or permantly disable it.
