Yes it drops the sound in half easily from outside the grow room window u can hear a faint humming from the actual inline fans I have bungeed in the air to reduce noise vibration. I duct the actual duct muffler into my hall way quieter then an oscillating fan I paid 50ish $Dannoo93 - just a straight answer, please, as I need your help and have already poked around for info. It looks as though you have experience using duct mufflers. Do they work as advertised? Is there a specific configuration that works better than others? Big ups in advance.
Imho somethings are better to pay for rather then trying to build
