Sound Dampening

Postby PXRdriFT » Tue Jan 31, 2012 9:14

Anyone do any research into sound dampening? I've looked at different things from spray/roll-on applications to dampening material you lay down. Any opinions out there?

I've only ever used DynaMat, but I've seen Lizard Skin applications and I'm pretty impressed with the product: http://www.lizardskin.com/sound-control-insulation.html

Much better than DynaMat IMO
:eek:

you can do:
http://www.dynamat.com/
http://www.fatmat.com/ I've heard is good.

I've read about quite a few RX-7 people removing the factory rubber sound deadening and replacing it with something like dynamat.

Also check out Raamat by RAAMaudio.

I used this on my scion tc and the difference in audio as well as hearing road noise/rattles/bumps, was night and day.

I have lots of pics I took during the install that i think i have up here but will try and find them and post tonight.

I've used Fatmat and Dynomat. Fatmat appears the same, but is tar-based and stinks for awhile. It is cheaper, but I wouldn't do it again. It also will get a little stinky in the sun.

Dynomat is fine, doesn't smell and is very reputable. There are certainly cheaper alternatives, just make sure it's not a rebadged product from Home Depot, like fatmat...unless you enjoy that "fresh pavement" smell.

Raamat A+++ Stuff is awesome. I used 2 rolls that weighed approx. 24 lbs each, along with the roll of foam which was very minimal in weight. This brand came recommended from an Audi S4 owner who used to compete in car audio competitions.

Here is one search you could check out just to see people's opinions.

The road noise as well as the awful wheel-well noise, was loud before and was beautifully quiet afterwards. Plus the music sounded better. I applied it in the doors, behind the speakers, everywhere.

You cut it into strips, depending on how tricky the area you are working with, and then heat-gun the stuff and lay it down. Run a roller on it, clean up the goopy residue (if you want a clean looking job) and then let dry. Afterwards, you apply the foam stuff on top with a sticky adhesive from a spray can. Looks good, sounds even better.

I am now thinking about doing this to my mazda too. You'll need a few warm days to do it all right.
