I have a stealth grow in two closets in my room. It's way too loud though and there are people in my room often. My veg room has a DWC system running on a big air pump and a drip system running on a small air pump. These pumps get pretty loud. The big one has a knob that controls the amount of air pushed. Should I lower it to its lowest, and quietest setting? I was thinking of putting some foam under the pumps to lower the volume. Is foam a good idea or is there anything better, like that mat stuff? I could also build a fan box type device and stick the pumps in there. As far as the flower closet goes I have a squirrel fan thats a little loud, an inline that's not that noisy and an oscillating fan that is WAY too noisy. Im going to attach a carbon filter to the squirrel fan which should lower the noise. Im also going to put the inline on bungie cords, not gonna build a box. The one thing I have no idea what to do about is the oscillating fan. Any suggestions? Pictures to come later as I am currently at a friends house.

Anyone try noise cancellation like in the bose headphones?
This is setting up a mic in your room and having speakers on the outside or facing the area needing to be quiet. The speakers play an inverted signal and cancels audible noise.

Well, its impossible to see in this picture, but the 8" fan mounted to the ceiling for the filter was extremely loud - like you could hear it throughout the house. I cut off a couple pieces of this thick rubber mat, drilled holes where the mounting screws would go thru them, and put a piece under each foot of the fan. Quiet as can be. You can hear it on the other side of the un-insulated wall, but that's it. Cannot be heard outside, or anywhere past the adjoining room.
For the both of the 6" fans ventilating the lights, I had originally set the lights up with the fans near an exterior wall, and it was very loud as you walked past the window outside. The other end of the system went to a window that is near the middle of the back of the house. So, I reversed the system, and it is nearly impossible to hear when walking past the outside window.
Hope this helps someone! Happy Growing!

Just a hi-tech solution. Maybe its unnecessary but I thought it would be cool and possibly quite effective. Plus, it would take into account all the noises - not just a single piece of equipment. You might be able to seriously stand and talk by the mic in your room and no one would be able to hear you outside.
Maybe I'll get it down and start a business
thanks guys.In summary:
1)cover the fan with wood (put the fan in a wooden box ) @ thanks to one2threeBUDS4
2)
cover the box and if it possibe,cover the all your grow room with Fatman or daynamat nosiy reducer
thanks again.good topic!

Another way to reduce fan noise is to use rubber feet either side of the fixing plate and screw through them, using a suitable washer on the screw head side.
Also car acoustic deadening rubber will help with general vibration. Not sure if I'd put it in a tank, but underneath on the floor it should help. Example: eBay Store - Sounds Great: Dynamat Cascade: 10115 DYNAMAT Original 2-Sheet Speaker Kit Brand New
Also beware of corners in a room, these act like a trumpet and increase noise. If you can mount fans / ballasts away from wall and ceiling corners, or 1/3 way between small walls this should help.
John - ballasts will make more noise over time, if your's is a few years old, it may be worth replacing. Try mounting it on rubber feet, or a foam/ rubber base and aim your circulating fan towards it. A high density foam block, like a yoga block should help.
thanks.but i wonder these methods are dangerous ? is there fire or explosion risk ?
thanks again.good topic!

Two things I've found that help a lot: speed control for the inline fans and insulated ducting on the outflow side. After determining how much air i needed to move, I put in an oversized inline fan. i then added speed control. Cutting RPM's on an oversized fan dramatically reduces noise while still moving the right amount of air. The other trick was to add about 6" of insulated duct on the outflow side. Pick up at Home Depot or Lowes. The duct is fiberglass insulation within a mylar jacket. this really cuts the noise from airflow itself. Like the poster above, I wrapped my fan in a fiberglass jacket held in with duct tape - not very pretty, but cuts the vibration noise eminating from the fan. The enclosed box is much more elegant of a solution. S.G.

just came up with an idea ,it works a treat .cheap ,quick way to reduce noise from inline fan.i just took my fan out measured it if it is 300mm /1ft add 50mm /2in to overall size then measure the thickness mine was 300mm x 150mm/1ftx6in found a cardboard box similar size, bigger is better ,then cut two holes out of both large sides mine was 100mm/4in cut two circles out of box on opposite sides, then wrapped my fan with clingfilm or similar taped two bungee cords underneath the fan ,looped these back to top then filled with expanding foam left to set for 24 hrs, cost me £4.00 for foam ,took ten mins the bungee is to hang it up with, and reduces vibration a good deal.ps tape box back up to reduce foam leaks then leave 24 hrs.it adds no extra weight at all pps i think this forum is great hope this helps someone .

Squirrel caqge fans are louder in my opinion and don't move as much air. I've built boxes for all of my fans except one (4inch). I run a ten inch fan, so if you think a 6 inch fan is loud... my ten inch can fan max sounds like the prop on a fan boat in the Bayou. The cool thing about Can Fan Max fans is that they fit into insulated ducting. The key to quieting fans is the air going out of the fan. The boxes help but most of the noise comes from the movement of it going out. They make a few "silencers" I'm sure that they can be made by hand quite a bit cheaper than they sell for in stores or online.

Sounds like a great idea!
Any chance for the cardboard to mold or catch on fire?

I made friends with mt neighbor, he's this 50 year old dude who's really into whiskey so sometimes we have a drink. When I'm at his place I always listen to see if I can hear anything, and I can't. If you can find an excuse to visit your neighbors, why not check for yourself if it's too loud.
One thing I do wonder about is if he can hear it at night, when everything is quite, especially since his bed unknowingly shares a wall with my grow room...
Either way I'm not too worried, he said he likes to smoke every year or so, and we've become good enough friends that he wouldn't rat me out. Get your neighbors to be friends, but don't share your secret with them unless you'd trust them with your life, cause that's kind of what you would be doing.

The only problem with that is if you go over to your neighbor's house and spend an afternoon with them, and you find out you CAN hear your grow room from his place, then it's too late and they can and probably have already heard it.
Odds are that they don't know what it is, or think it's a big freezer or something, but who knows.
The whole point of sound control is to stop it BEFORE someone takes notice. If you only control the sound AFTER someone notices it, then it defeats the purpose. You arn't doing sound CONTROL, just playing sound CATCH UP.
