is that a duct muffler sitting on top of the of the inline fan, if so how does it work? sorry if i missed the answer along the way...
really digging your tissue culture thread as well bro!
it is a duct muffler. there like $100 in the stores therefore i make them my self for about $25 each. they do a good job
i recorded how much noise the scrubber makes with/ without the muffler and at 5 and feet away. with everything in the room shut off
full blast@5 feet way
+ muffler 64.5 dBa
+ no muffler 69 dBa
fullblast@ 10 feet away
+muffler 64.1 dBa
+no muffler 67.5 dBa
this means the muffler reduces the sound pressure created by the fan to less than half of what it would be otherwise. as a 3Db drop causes the
sound to be precieved as half as loud.
