Keep me updated on how that works out, I'll be in the market for some stealthier equipment at a later date.

My friend had a hydrofarm 8" inline that was pretty well balanced. Much better than my generic.
Its got a lot to do with the mounting hardware. Some cheaper fans let the thing rock back and forth so you have to use a block of wood or something to support the fan. Or if you add some sort of support on the other side to keep things from swinging you'll notice much less noise. Bolted down on all sides if you can.
compare mounting styles of the hydro farm with brackets on both sides
versus this generic with only one side, gonna swing back in forth like a mofo.

Yea, I'm hoping to eliminate most of that by building a 2x4 frame and plywood shell that will encase the fan itself, and rest it in a tightly-packed bed of foam and insulation...to dampen out all sound or vibration.
This assembly will be hung from the ceiling by elastic bands to further isolate transmission of vibration from the wooden frame into the external beams of the room.
I downloaded a dB meter app on my phone, and did a test of the room with the bare fan running, with 8 feet of flex duct attached to the intake and exhaust of the fan as a baseline fan noise level. I did the same directly outside of the room. I will compare those measurements with the final readings once its mounted and hooked up. I have no way of knowing, but i would love to see a 10 dB reduction in noise level in the room.
