[QUOTE="squeak9798, post: 1381935, member: 555320"] There's two types of sound deadening; Mass loading and Barrier loading. Mass loading stops vibrations and resonances in panels and works via adding mass to panels. Mat based deadeners like Dynamat Extreme, Raammat, SS Damplifier & Damp Pro would fall into this category. Barrier loading is what actually absorbs and reflects airborn noise. Open and Closed cell foams such as SS Overkill, Ensolite, etc fall into this category. Liquid deadener is sort of a good combination of both. It works as an effective mass loading sound deadener (though some would argue not as effective as mat), but also has good barrier loading characteristics (much better than mat, maybe not 100% as good as foams). For the purposes you want, you would probably want to use a combination of all three. Something like a layer or two of mat deadener to cut down on any panel resonances, the follow that up with 2-3mm of liquid deadener, then 2 or so layers of foam. Honestly a very good idea would be to give Rick of Raammat and Anthony of SecondSkin a jingle on the phone and see what they suggest. I would, personally, get Raammat sound deading mat and Ensolite foam (sold by Raammat), then some SecondSkin Spectrum for the liquid deadener. [/QUOTE]
