I have a 6 inch 400cfm centrifugal fan with a speed controller. Even with the speed turned all the way down it sounds like I have a dryer vent exhausting out of my bedroom. I have a carbon filter inside the tent with about 2 feet of rigid flex tubing connecting to the fan and another 3 feet of the same ducting connecting to the exhaust point. The noise is still noticeable from over 15 feet away.
It sounds like my best option are a duct muffler and insulated ducting. My question is, is this going to eliminate the "whooshing" sound or at least bring it to point where you have to be standing within a few feet? And, is it any help to increase the length of my ducting?
I want to maintain a quality air exchange, but stealth is definitely a gold key and right now there is just too much noise from the exhausting air.
Thanks!
Are my expectations unrealistic?
