Whats up with people going crazy with sound deadener?

i personally think its all just a misunderstanding of how people want to make their car quieter.
people dont understand that rubber mat is designed for vibrations, not sound deadening.
In many cases, I think you're right. I mostly hang out on automotive forums. One board, in particular, dedicated to an extreme performance machine sees owners covering the entire floor and body with deadener in hopes of creating a quieter environment. I've lost count how many times I've tried explaining the concept, even linking Don's site, to absolutely no avail. Worse, folks use asphalt-based materials, insisting that it's just as good as anything else, layering that crap over everything. It's like a disease that has no cure.

 
Certain deadening companies help with the spread of this disease. Many people see their employee's build logs or those they endorse slap on way more than enough CLD tiles and think they need to do the same. It's either one big marketing scheme or they do not know what they're doing, or a combo of both.

 
I just read this thread
http://www.stevemeadedesigns.com/board/index.php?showtopic=63972

Along with countless others.

What is up with these people loading shit tons of deadener all over there car? Check out some of the videos in the thread....I mean the speaker taps on the face of bare metal, and then taps on the same metal with sound deadener and exlaims how big of a difference it makes.

WOW what a breakthrough...im sure wiping the metal down 2x its original mass in liquid nails and shit would have the same effect...mass loading is mass loading.

What I dont understand is people going crazy....putting 10x the ammount that is needed all OVER there car.....killing mileage..hurting resale...costing themselves money.

Please explain to me why applying 10,0000 layers of deadener to the same spot, along with applying it to vibration dead areas will have a substantial effect over 1-2 layers spaced in strategic locations, otherwise I will continue to believe this is all a sales ploy.

I have deadener in my car BTW.
10,0000.... i love that number....

 
If you want to reduce noise, then you need some Luxury Liner, or MLV. Sound deadener is not a good noise barrier.
I did both. I did notice a huge reduction in road noise just from the deadener, but a bigger difference when I added the closed cell foam. I need to do my roof now. every time I quiet one part, a new noise pops up. :p

I hope nobody's doing that with CLD Tiles //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
