Dear Dan:
Sheetrock finished smooth will cause sound to reverberate within, and if
you can either put a very rough finish on it, or cover it with a material that
is rough in texture, or hang some oriental rugs on the wall, the sound level in
the room will be decreased, and in turn, reduce the amount of sound that
escapes to other parts of the house.
My first wife and I have just removed wall paper from a bathroom, and
painted the refinished sheetrock which was exposed, and the echo in the small
room is increased, even though the wall paper was smooth. Your shop might look
a bit dainty, but find a bargain in flocked wall paper, and apply liberally.
Yours Truly,
Clifford Wilson

Subject: [BlindHandyMan] Noise reduction.
So, in the fantasy world in which I live, one of my projects is to wall
off one end of my basement to make a shop where I can go and make dust and
noise without getting dust and noise all over the rest of the basement and
house. I realize I won't make a sound proof room, but I would like to
take some steps to reduce the amount of noise that will bleed out of the
shop area.
Here are some of my thoughts, any corrections, additions, or ridicules
will be accepted.
The wall will have a footer and header that are 2X6 instead of 2X4. Then
there will be studs staggard two one edge or the other. Thus, there will
be no stud that reaches from edge to edge, so no bridging. The cavity
will be filled with fiberglass insulation. The dry wall on the shop side
will be mounted to Z bars instead of directly to the studs.
Lots of fiberglass will be stuffed up into the joist bays overhead and
then acoustic tile as a ceiling.
One major question I have is dot dot dot.
The wall runs parallel to the joists, so should I run the top of the wall
up between two joists, but not fix it to joists or floor and then stuff
lots of fiber glass around the top edge, or do I absolutely have to fix
the top of the wall to something. Obviously, there is a rigidity issue if
I don't. The ends of the wall can be fixed to the cement walls of the
basement, if that is enough of a substitute.
Most of the sound will be high frequency sounds so doesn't fiber glass
batting and sealing up cracks take care of most of that sound?
Without trying to make a sound proof room, are there any other things I
could do to reduce the sound bleed?
