Sound proofing an automobile
« on: October 28, 2012, 12:06:00 AM »
Looking for a forum that deal with auto soundproofing! Assuming I have come to the right place I have a few questions. # 1. Sound absorption or sound deadning or something else? # 2. Weight, looking for lightweight materials # 3. Any help I can get! Thanks, Bill

1) sound deadening is a better bang for buck but it will add some weight (about 1.25lbs per sqft.)

2) you can use our lightweight ssp foam mat for head liner and side panels and even under the hood.

3) we also have sound dampening paint for the under body as well.

I am new to soundproofing as well and had a few questions of my own about sound proofing my car.  I was thinking of using 1/4'' of CCF and on top of that 1/4" MLV.  My question is would this be the best way to arrange the material?  Another way I thought I'd attempt it is 1/8" CCF + 1/8" MLV on top + 1/8" CCF on top of the MLV + 1/8" MLV on top of that.  Essentially, you have alternating layers of 1/8" CCF and 1/8" MLV.  I was thinking that in this configuration, you would be providing some isolation for the two different layers of MLV so this way, they can block out more sound since each isolated from the other.  Any ideas on which configuration might be the better one to use?

Just use the 1/8" MLV bonded to 1/4" ccf one layer is fine. with 2 layers you are most likely already past the diminishing point of return do to the sound blocking value of your windows.
