yeah tod here england i have had major problems with sound when the bubble pots fans and ballast are buzzing parranioa sets in well you want stealth go to carpet centre thick wood floor underlay and silver sound proof pack your pots underneath and your ballasts even under fans 200 mm or even less .........happy days can't hear a whistle

johnny go to bQ and buy two big rolls of thick laminte underlay then buy 1 4mtr square accoustic sound padding all your probs will be gone fold the underlay as thick as desired and put sound padding on top hope you do well tod yoda

why express lies

good idea my room is away from the house but still noisy to me when people r around def. gonna try egg crate on the one wall thanx

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

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.
