sound proofing a room.

[noworries]

I am going to be setting up a grow in my garage bay from scratch and want to do it right.


Smell and light leaks I know how to correct, but sound proofing will be a big priority for me and I know nothing about it.

I was considering using that sound proof car stuff, dynamat? i think it is.

Then I saw this on amazon Moving Blanket/Sound Dampening Blanket (Single) 72" X 80" Super Soft Premium Moving Pad (90 Lbs/doz, Black/White)

I have 0 experience regarding sound deadening so...i'm all ears =P

Acoustic foam+quietrock or some similar combo

real simple
build two walls. Use roxul fire and sound insulation. its extra dense to stop noise and fire treated. Its basically extra dense rock wool.
The interior walls should be hung on sound bar or z-track, and left 1" from the ground all the way around the base. The bottom 1" is filled with a 1 1/4 backer rod made of closed cell foam. The backer its covered, and the remainder of the gap is filled with a flexible caulking made of polyurethane or elastomeric caulking. Tool the caulking smooth and paint over it all said and done the room is moisture tight, and the bottom 1" is waterproof.

Hang fans from bungee cords. Vibrations are the sounds i hear the most. Duct mufflers. I have a central air unit, 2 ten inch fans and 2 eight inch fans. I simply laid thick moving blankets over the garage door, then built a room inside the garage. paper backed insulation. it's pretty hard to heard. central air unit is a bitch to cover up. spring im going to have the compressor moved from the outside unit into my lung room in a metal box like the xcel stealth units.

Check out insulation board like R-max, keeps heat in or out and has a great R value which will help with the sound.(its also really light and easy to cut with a sheetrock saw or razor knife. Only down side is you need to tape the edges... If your ducting is too noisy you can always double duct. For example put the 6" insulated ducting inside an 8 or a 10" insulated duct.

Bungie cords to suspend the fans helps a lot too. If your ghetto you can just carpet your lung room. I moved into a place once where it was clear there were growers before me... However it did allowed me to run my 12" exhaust fan with it being barley audible from upstairs.

Your other option is to build baffle box and line the inside with sound foam; if you have an appropriate sized hole saw for you fan. These can drop the dB down quite a bit, but make sure you get the plywood or sound insulation boards real flush with one another or the vibrations can hammer the boards.

good luck! Also keep noisy stuff 6-8" away from the corners of walls and the celing corners if possible. These parts of the room can act as Bass traps. Some times your sound can get much more absorbed in the room by moving equipment around just a couple of inches. [I use to work as a sound engineer]

Prodex is what you need. http://www.insulation4less.com/
Prodex and 2 walls. Good luck. -granger

for sound proffing first: Dual wall/Roxul insulation/Resilient bar/sonopan(green stuff)

 

[onthaherb]

So from the inside out:

Panda Plastic for reflectivity
pinned to plywood wall with roxul behind
pinned to resilient bar
plywood outwall with sonopan on the inside?

 

[overbudjet]

For me from inside out tile glued to/gysum pinned to/resilient bar to/sonopan to/first wall filled with roxul/second wall also filled with roxul/gysum on the other side pic of the tiling job if you check closely you can see the layering at the entry.

they have products foor sound proofing, buts its pricey.
go to vinyl siding/aluminum supply houses
and get the eps alum-foil lined foam panels, 2" thick.
they come in 4x12 sheets, also makes for killer top notch insulation!
