Sound Proofing and MLV

A large part of the benefits is the weight, not just the fact that it is a solid barrier. Lead is a better, thinner option, but you a) have to work with lead b) cost a lot more.

What are you trying to accomplish, and where, with a rigid product?

Check out the write up on www.sounddeadenershowdown.com, and check out http://www.mobilesoundscience.com/ for some great info. There are a couple of industry guys (past and present), and a LOT of info about what works, what doesnt, and how to improve things.

 

no. MDF or OSB will not do the same thing. Plus, how could you get that into your door or under the floor?

 

I'm not putting it under the floor or in the doors.

I removed the plastic storage bins from behind the seats. I'll be cutting off all of the tabs that are back there. This leaves me with a large, relatively flat, surface and a beam horizontally down the middle.

What I want to do is fill in the corrugations with the CCF, then run a layer of CCF across the whole surface above and below the beam. Then I'd like to make up carpeted, rigid, panels that will span from floor to beam, and from beam to top.

Hope that makes sense.

Here's an image that shows the back wall. Everything outlined in yellow or red is getting removed.

 

It should be fine, but it will not do a lot to block sound, as the weight is not there. Should definitely clean up the look though!

 

If you really want to do something right here's what I would suggest...

Get some of the 1/4" CCF and bond it to a layer (or two) of MLV. Attach this to your carpeted MDF board by spray glue or possibly a few screws. You could easily get by with 1/2" MDF. There's no need to go any thicker considering it's only there for aesthetics.

This way you'll get the sound blocking advantages and the look you want.

 

Got an email back from Don. He said he doesn't know of anything.

I think what I'm going to do is fill the voids with strips of CCF, cover the whole thing with a sheet of CCF, and then make up a board of maybe 1/8" masonite with a layer of MLV glued to the back, the carpet the face of the masonite and press the whole assembly on top of the built-up CCF.

Was hoping not to have the extra thickness of the masonite AND the MLV, but that's fine. Might just make up the whole thing the way ItalynStylion mentions as that might result in just two simple boards that I press-fit into place.
