They are very quiet but I've never herd them without the insulated flexduct hooked to them. I've had other inline fans with noise reduction mufflers on them and even tried those week ass panasonic whisper fans and nothing comes close. My owners books says the td-350 uses only 22 watts and has a sound pressure level of 33db. Hard to get better than that Most other 6 inch inline fans use 100 or more watts and db's are in the 80's so that should tell you what your looking at. Not sure what brand you have so may want to research your info and see to compare. I that do know they underate the cfm flow on the S&P fans because my 6 inch cools the same as my old 6 inch vortex used to with a lower cfm rating. I tested this buy the light temp on the reflector glass.

Tony did you have the insulated flex duct on your vortex? I've heard manuf. underrating fans but that seems like a lot of CFMs to make up.
Ive got two of these...a 800m3 and a 500m3 fan.
Both require silencers if you want ultra quiet. Ive two 900mm silencers on the 800m3 and two 300mm silencers on the 500m3 fans
They are ultra quiet and brilliant purchases! No question Id buy them again without hesitation!
One thing I would say is that You need a larger silencer on the output, so really I should have gone with a larger one on the 500m3 fan but it still is quiet especially when you use acoustic ducting, which I also use
