[Rwp] Perhaps a Bit OT: Silent Fan

[Chris Belle]

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.
