Fan noise, sound proofing

[scott9116]

Has any one used heat/ac duct as wall covering, you know the kind that folds up into those square ducts? Mylar on one side yellow fiberglass insulation on the other about 1" thick. My grow room is completely sealed up from the rest of my house secret door etc. I do get some smell I think from opening the door. But,y problem is noise, odd fan like noise coming from a wall in the bathroom, can't hear it over the bathroom fan but when it's not on there is noticeable noise from the room. I wonder if this insulated mylar would kill enough noise.

Get some foam for the area around the fan, or insulate your grow room. Imagine your plant is a mic and make a sound proof box for it. at least a deflector. Also if your fan is mounted somewhere you may want to make a shock of some type cause it may be causing noise from vibration. The bed foam from wal-mart works I guess, the thicker the better.
Hope I helped. google sound foam to research

Thanks, Prunedale. As a musician/soundguy I know a bit about acoustics but was just wondering about that ductboard stuff and if anyone had tried it. I don't know if 3/4" of insulation would do it. The foam in the studio works great but is so expensive it ridiculous. I think if I move my cloning cabinet to another wall it would help some. I was just thiking of killing two birds with one stone; mylar and insulation in one package. I'm just cheap and wanted to use somebody's experience rather that spend the cash myself (might as well be honest).

One idea might be this stuff you can buy at HD, I have seen it used on the back of a garage door and works well for heat/noise, it's basically bubblewrap sandwiched between 2 sheets of mylar. Good stuff but I forget the name, its in the section with pink fiberglass insulation Another idea might be to get one of those light/fan combos for your bathroom...so the fan comes on with the light. People gotta be able to see what they're doing in there hehe

for fan noise there is nothing like Dynamat..its a little expensive but it works like a son of a bitch

I wouldn't use the foam acoustic insulation. It's usually pretty flammable.

If you go to Strains and Seeds, and look on Page 3 of the post Low Odor Strain Help you will see what I told Orangeman to do in order to make his fan soundproof. Build box, use foam, hang from ceiling, etc. Its too much to type out and I am entirely too lazy to go look and copy and paste.

great stuff

just spray it in all the lil nooks and cranies where the fan comes into contact with the box

**WARNING** greatstuff expands upon drying and therfore apply it sparingly and not to moving parts

Dynomat is used for vibration muffling not sound.....

Your best bet is really to buy the soundproofing foam, its like 5-15 bucks a square foot and ideally you dont need all that much of it, just enough to muffle the sound, u could use it every other square foot or u could just put it around the walls the fan is near to minimize sound deflection. If you know about sound most of the problem is the deflection and reflection of the waves, so all u need is a little bit but in the right spots good luck.

I had a similar problem all i did was moved the fan from one side of the room to the other

I know this is entirely too old of a post but to anyone whos still out there. I have a similar problem and was thinking that egg cartons, which can be used as a soundproofing substitute, might work. Any thoughts?
