Audio dampener install - Second Skin Damplifier (lots of pics!)

[jzilla]

Any updates on the Damplifier pro install? Any others that have done it? How much do you need just for the floors?
Thinking of ordering some up and doing that as I do the diesel swap.

Thanks!

i did this in my hj60, and it made a difference, i would not say enormous difference, but enough to make it worth while.
I used two packs of damplifier pro and some sheets of closed cell insulation material. It is now possible to have a normal conversation at 80kmh with the passengers in the back seat even with my loud straight pipe exhaust.

i put damplifier in all the doors, floor, firewall and in the rear quarter panels. I made a double layer over the transmission tunnel plus the foam mat as you can see in the picture.
It did not make my sixty lexus quiet, but it removed the worst of the noises and made it more civilized, also the "closing door sound" sounds much more exclusive now i would do it again.

Where did you order the closed cell blanket from? Does it look like it will hold up?

Anyone consider FLEX Seal?

Secondskin is a great choice. They are pretty much one of the best for sound deadners.

You really don't need 100% floor coverage with the butyl mat. It is designed to be a mass loader, and eliminate structure borne noise (ie. rattles).

The foil mats are best used by placing pieces in the middle of the largest panels (ie. rattle focal point... remember the rattle is from a low frequency sound wave). The more the merrier though....

These mats do very little to block higher frequency sounds (ie. wind/road noise)

For the higher frequency sounds you really need a barrier like MLV (mass loaded vinyl), or foam, or jute, or carpet or a combination of those.

Hope that makes sense.

Be cautious with what "sound deadner" you decide to use. Some name brand products are actually crap. I have tested several them and many melted over one summer.

FWIW those "in the know" use a roofing product called "peal and seal". IIRC The newer formulations are high content butyl, much like the good sound deadner products.

It's made to withstand the harshest environments (like on top of a roof). I have installed in in many vehicles, and it is still intact after several years (I live in Arizona... car temps can get up to 180* in the summer). Only problem is that it comes in 6" rolls so the install can be more work. Oh, and it does not smell, at all, like some people claim.

I will probably get flamed for that one...

A friend used "peel & seal" (the yellow 'skinned' stuff from Home Depot) in a project 510. It did have an odor when first installed, but it wasn't even close to over-bearing and it completely dissipated in a couple of weeks. It is what I've been thinking to use in Wallace.

Another friend used cut up Ensolite closed cell back-packing foam pads over the mass loader to further insulate the doors on his 4wd. Those doors close like they're some uber-spendy lux-o-boat. That stuff isn't always inexpensive, but I've seen it on sale at Campmor and Sierra Trading Post every now and then.
