Very good thread....
Also, a good way to bring down the noise level generated from fans, is to not use old, busted down equipment...Like i have and planning to change out my old soviet union fan, that makes the noise of a soviet union tank lol:lol:





:peace:

My friend is using a caulk called "Grabber Green Acoustical Sealant." I'm not sure where to actually buy the stuff as he picked up 4 large tubes left at our last job site (you'd be amazed at what gets left behind when a building goes up). Anyway, it claims to deaden noise. He used it on all seams/corners of his room.

Building a box around your fan is a great idea. Another thing, if you have the space is to build an enclosure that your fan and filter can fit into. Line it with "egg crate" foam and remember to leave enough of an opening to allow fresh air in. The foam works well to absorb that sound.

Just wanted to add that if you are in the market for a new fan I would check out the max fans. When I compared fans I found that a 10" max fan makes about the same noise (different pitch sound though) an 8" vortec.
The 12" was much quieter than a 10" vortec. There really is more than cool looks to the Max Fan.

From on top of my head:

1. Build a fan box with foam, rockwool and plaster
2. Build a muffler like this one: http://www.icmag.com/ic/showthread.php?t=42646
3. Reduce bends and turns in the ducting as this increases noise, lowers air flow and therefore creates need for higher fan speed.
4. Use straight rather than flexi ducting. Isolated of course.
5. Put air pumps on 4 inch matress foam. It really helps a lot
6. Use more air stones on the same tubing (using T-forks) to increase resistance in the tubing. Tubing clips can also be used. Pumps makes most noise when pumping unrestrained.
7. Test several air pumps before you buy as they differ a lot.
8. Test several circulation fans as these also differ a lot. 6” clip ons are great for low sound.
9. Building a sound proof grow box with multilayer walls: Plaster-air-rockwool-plaster (plaster is very dense and great for sound reduction)
10. Get your self a big fluffy carpet.
11. Place anything vibrating like reservoir, air pump, PC fans etc. on matress foam as it kills vibration dead.
12. Use a voltage reducing fan speed controller rather than resistance increasing versions, as these can cause fan hum.
13. Keep your big fat mouth shut! Lol!

Hey, Can't you just use empty egg cartons and stick them on the wall of your grow room, shut the doors, etc.. sound' shouldn't be to much of an issue I hope. ;-)

im sure its been said several times, but just in case no one has mentioned it...

i use old bicycle innertubes to hang my fans and they work great for reducing vibrations and u can usually get them for free from the local bicycle shop...

Yeah... I'm sure the carbon filters with all that surface area are designed to USE that area to absorb odors. If you build a box around the filter, your making the fan work harder than it has to and you're defeating the purpose of the carbon filter as the CFM will be drastically limited. :wall:

i am very new at this
so bear with me ....
i live in a small apartment i am setting up a small grow (10 plants or less). I am using 400 w metal halide in the early stages and a 600 w agrosun super red sodium for the later stages. I will run it off a next gen 400w/d00w electroic ballast. I have a xtra sun air cooled reflector. I havent designed the grow box yet. I think it will be 3x3x5 (roughly). Does anyone know if i have to worry about the extra electricity drawing attention?
thanks

Ok dang it im aat work and i cant read this entire thead, although i wish i could.. anyway i have a 120CFM inline duct fan from home depot and GOD DAMN , I bet the lady upstairs feels like shes sitting on top of a rocket ship.. anyway long story short i gotta shut that thing uup QUICK... Im not a very good handy man with wood so i doubt i could make this box.. Would it make sence for me to get a more expensive, and hence quieter fan ? This inline fan is just used to cool my sealed hood for a 250W HPS...


Can i get some suggestions that dont really require too much construction, if at all.... Great thread btw

For DWC: My problem isnt at the pump, its at the end of the tubing. I have an idea on how to fix this but havent tried it yet, ill update you guys when I do. My DWC bucket is a 3gal, Im going to set it in a 5gal stuffed with foam of some kind to absorb the sound. water cant pressurize so it will move the walls of what ever it is sitting in (if it can) (concrete buckets anyone?) ... so ill let you guys know soon. also, maybe it would be possible to create a pressure stabilizing "muffler" before the airstone.

Here is another untested idea, for whooshing duct noise. Besides the fan, the noise is created by the air moving past the ribbed walls at hig speed. SO. at the fan outlet use a duct size adapter to increase the duct size, and use a larger size ducting to exhaust. You will move the same volume of air at a lower speed, thus reducing "woosh".

good luck!

Ok I just discovered something. A t valve has three connections (not what I discovered). Hook two air pumps together, run the third airline to your water and attach the air stone. Plug in only one pump. Its quiet. At least for me it is. If someone else can replicate this let me know. Note: With two different air pumps in use I didn't notice a difference if one or the other was plugged in.

maybe im just stoned but i dont get it... but i have a dual air pump (2 air lines on one pump) and the thing is pretty loud.
