plugging windows to keep out traffic noise
« on: April 01, 2001, 10:45:04 PM »
I want to make a temporary plug to completely block traffic noise from
getting in my windows, so that I can tell how much noise is getting in through
the walls -- I'm doing the walls first.  There are about 50-55 dBA getting
through the windows.  I have about 2" of frame space I can fill up on the
inside, 1.5" on the outside.  
What would work best?  I tried 3 layers of 1/2" drywall on the outside -- no
caulking, it's just stuck in there pretty tightly.  That helps some but there
is still noise getting through.
Would homasote panels, say 7 thick, work?  Or how about
alternating 1/2" soundproofing mat with homasote or
drywall?
Does homasote keep out traffic noise better than drywall does?
Thanks

Why not use the proper material:  foam: see the link below!
