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.

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??

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…

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.

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

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

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$.

I want to deaden the doors in my Escape so you can't hear the door speakers outside. Currently there is a factory deadener/insulation behind the plastic door panel, so that would come out and be replaced. What should I use to replace that and then what should I use to cancel noise from leaving the cabin? And how much of each for four doors.

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…

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…

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'm about to sound deaden my 1998 gmc jimmy. Has anyone every used the product b-queit ultimate? Also how much should i use. I've heard that only 25% coverage works perfect. I'm not going for insane spl numbers i simply want to stop rattles, and make it sound better on the highway? Any suggestions on better products around the same price? How much to use??

so my second skin came into day. 67 pound of HUSHHING furry lol. i got a bulk pack 36 SQFT of damplifier pro 4 sheets 36 SQFT of luxury liner pro maybe too much! and a pack of speaker tweekers ... started on it today.. lincoln doors are very hard to get in, only 1 small opening . i can say so far.. the damp pro goes on nicer then other products, is sticking well, and it looks good.. ok back to work!!

This has probably gone over HUNDREDS of times but the search function didnt give me the results I was looking for. From what I have read sound deadening will make you lose spl? Well I like my sub being loud but I hate the rattle from my trunk. What is the best way to apply Second Skin (Seemed to be the best) without losing the loud boom that I am going for? Any help would be appreciated. Sorry to those I anger with this post. Thanks, Jeremy Also....Has anyone ever tried Spectrum? Seems easy enough.....

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…

So yeah basically about 2 yrs I installed Rattle Trap extreme in my car. Over the past few weeks its been extremely hot in san antonio and I noticed that there was something leaking out the side of my door. Doing further investigation i discovered it was the rattle trap extreme melting from the inside of the door through the drain holes in my door. So i decided i might as well remove this crap and then i noticed quickly it was too easy to remove it off the outside of my door panel. But as I was about to begin removing it on the inside of the door i realized it was way too hard using physical strength. Anybody know the best way to remove the rattle trap extreme and clean o…

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.

Ive searched and searched for any info about how to decrease the noise created by my Thule 686XT Atlantis 1600 Roof Box to no avail. Is that because its simply a silly thing to try since it just makes so much noise? I have done no sound damping to my Subaru Impreza, but plan to address noise coming through the floor, hood, doors and roof. my question is this: Is there something I can do to the box to get it to resonate less? Or do i simply focus on the roof and possibly, load bars and rails? Thank you very much for any help you may offer. Noah

So i was curious on some of the responses of the murder mat. The MDK and the BL series. I am really gonna need deadener after i get my seccond gcon in my van coz it already rattles enough hahahaha.

I'm ordering new carpet. Will soon be outfitting the truck with SDS, but want to know if I should buy the mass-backed carpet for an extra $50 or not?

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?

After googling around and not having any luck I decided to post here because of the "vibration control" topic in this forum. I would like to mount my amplifier on the back of my box without rattling it to death. I have looked at some youtube videos ( and it looked like he has only a mdf board between his amp and box. I was looking and found several things on the net but lots of them are expensive:Silicone Anti-Shock mats Rubber Screws Anti - Shock pads Anti vibration mats I do have some of the foam they use to sound deaden recording studios so I was thinking just putting three or four mats of that sandwiched between either a soft or hard piece of wood to mount my amp on…
