[Rwp] Perhaps a Bit OT: Silent Fan

[Marion & Martin]

Chris,

	Thank you very much for your suggestions. I have considered creating
some duct work with a couple turns in it and insulated with foam, something
like the eg crate mattress covers, bringing the fan from the floor to a vent
in the ceiling. Lowes sells 2-inch polyfoam wallboard and I am considering
using this on both the inside and outside of the room with R-30 insulation
in the frame space. I have also considered using a double layer of carpet
padding on the floor and even floating the frame on it. Using an acoustic
caulk to attach the wallboard might be a good idea. Since the room in which
the booth will be located is a converted garage, the walls are concrete
block with an 8-inch concrete foundation. The biggest concern I have from
the room - other than the window unit, is the 5 X 8 window that acts like a
drum when a loud motorcycle or car goes by, especially when they are blaring
the bass! 

	I am thinking about making a YouTube video of the construction just
for fun. Any other ideas are greatly appreciated!

Peace!
Marion

If you go to
www.acousticalsolutions.com
that's where we got a lot of our studio treatment stuff.
The basic idea is you want larger, slow moving fans.
Also sound can't go around corners and turns and such as well, so an
insulated duct that winds around a bit will help to stop sound.
YOu can get quiet promoting bent covers as well.
When we did the studio here, we made the intake vents on our ac a lot
bigger, slowed down the fans, and made flex duct instead of those metal
ducts which are noisy as heck and transmit lots of sound.
YOu can get non-conductive flex duct and put it far away from your fan.
Of course your efficiency goes down a bit but if you insulate it, that will
help, you also might consider using that vent you pulled from the house to
cool your booth which is a lot smaller space, and you can turn off the
window unit when you are recording but not out in the control room.
That won't work when a band is in there, but if you are working yourself,
you can sort of work it that way.
Those window units are noisy, you might need to really isolate that booth to
keep all the noise out, we used resiliant channel and double sheet rock and
mass loaded vynal, and all that stuff, had I to do it over again, I think
I'd give up a little more room and do double walls all the way around, we
live right by the road and there's a whole lot of noise, and there's only so
much you can do in an old wooden house.
It's pretty good none the less, we dropped a bundle for us, but the general
idea is the more layers you have and isolating the layers from each other,
and using mass, that stops noise.
I don't know what your floor is, but you might consider floating the booth
as well.
Most commercial studios have a nice concrete or cynder block outside to
start with to isolate noise, it can get crazy expensive, and the trouble is
that most contractors don't have the first idea of how to really do this, so
but you can get no brainer products like led impregnated sheetrock, and
green glue can be put between your sheetrock layers to help isolate them
from each other, and you can do things like leave space around your edges so
nothing touches and use acoustical calk so you're cutting down transmission
to adjacent walls, I like mineral wool too, way better than fiber glass, and
don't forget about your ceiling as well, we did a bit of a dropped ceiling.
they should have some good ideas for you over at that site and good luck.
