[Rwp] Perhaps a Bit OT: Silent Fan

Fri Mar 11 16:16:35 EST 2016

Chris,

	Everyone is telling me that the concrete walls and floors should be
sufficient to stop any outside noise; however, I still have the issue with
the window and the AC window unit. If I close off the window with that
2-inch polyfoam stuff they have at Lowes with a bit of foam on the back to
dampen the window vibrations, I might be able to achieve the soundproofing I
am trying to achieve, the remaining issue though is the window AC. Any ideas
of how to stop that noise from infiltrating my recordings without building a
separate room?we are getting a new central unit in a couple months, so I am
thinking of perhaps getting a 1/2 ton larger unit and installing a duct fan
to get a little more air flow back to that room. It gets a little warm
during the Florida summers since the room is on the south side of the house
getting direct sun for at least 8 hours daily!

Just use mineral wool anyplace instead of fiberglass.
I don't llike fiberglass, it's too light to really absorb anything, and it's
nasty stuf.
I'd even prefer that blow in stuff celulose to fiberglass.
Carpet is good anyplace,
and concrete walls you're in pretty good shape there, that's nice.
