8" insulated ducting is about a foot in dia once you add the insulation. Im guessing it would take 15' or so to make a nice loop exiting in the same direction as the entry to keep air flowing. It comes in 25' lengths so I'll see what happens. I'll need to get a DB meter to measure the actual noise reduction. I don't have one. Its gonna take up some space for sure.
Nice, someone doing it the right way. Just Kudos. I was just trying to explain this to someone else earlier today, it's like trying to reason with an hysterical kangaroo. Let me try this new merit thing on you. Edit: Seem like i can't send much but i did. Anyways, Good Job.
Thanks for the update. I bought some 8” insulated ducting at Home Depot last night. I’m going to do some longer runs. 8 foot or so to get the heat out of the room I have them in. I’m hoping the 8” size will allow enough flow at the longer length to keep everything cool.
An interesting test would be to do a straight run and then one with a loop to see if that could cut down on noise, but not affect cooling.

Forgot to update, I went back in and performed sound measurements. No change on the interior noise, outside at the duct exits is another story. Heat's not the only thing making it out! Now granted my run from the miner exhaust to the duct panel is very short less than 3ft. but the sound outside is approximately the same as inside. I never measure before, but I know it was not anywhere near as loud.
Interior measurements:
20' Interior Garage door closed ~ 45DB
20' @ interior door threshold ~ 65DB
10' ~70
At the miner 78-79DB
Outside at the exhaust exit ~75DB, I need to verify this again. Last night seemed to be a cacophony of airplanes, Harleys, and dogs barking

Foam board, or any foam for that matter does not "deaden" sound. It only controls echos of higher frequency sounds
(like drum cymbals or above the 12th guitar solos). Materials like mass loaded vinyl or Rock wool based insulation
"deaden" sounds. A much cheaper option is double layered drywall/rockwall. Or venting out into a box that has
a "maze" inside it. The box needs to be big enough to allow a good flow through it ofcourse.

I'll break out the decibel meter tonight, but I am pretty sure it had no impact.
Ok you may have just saved me a bunch of work for nothing lol. I thought I read something on here where they took an 8’ long piece of ducting. Looped it so it exited in the same direction the miner was pointing to help knock down the sound.
Ok I was thinking the 6” ducting would knock down the sound some. Maybe insulating the room would be a better idea.

I might have to look into getting a few of those.
Do you know of a good sound absorbing insulation board? My miners are on a 3' x 72" tall shelving unit that you can get a Menards. What I am thinking about using is 1-1/2" foam board. I would put a piece on each side and one on the front of the shelf. The front piece would have a hole in front of each miner that the ducting can come through. Now the back is close to the concrete wall in my basement. I thought if I space the shelve about 6" from the wall and put a piece of that same foam board on the concrete behind it that I would still get some good intake air flow and the board would help knock down the sound. This is all in a room in my basement. I wanted to leave the back open also for ease of access.

I have not tried to quiet mine down. I would think if you have the space just build a small room and compartmentalize the hot and cold side within that. Then just work out the appropriate intake and exhaust ducting.
My friend will be adding the duct adapter to Thingverse, so just search for Antminer. It should be there soon.

I also dump heat - (even in the winter in Wisconsin). If you only try to only provide cool air to the miner from outside - the room heat will eventually overwhelm the miners. filters are a bad idea imo they get clogged and you have a problem - you're better off having a air compressor and (carefully) blowing out the dust once a week. It's also a good idea to put some leaf/rodent proofing on the intakes - one errant leaf and mess up miner by blocking the intake - Also a 1" gap at the inlet side of the miner - instead of a direct connection allows for blockage inspection and adequate intake temp/cfm. In the case of a rainy humid day the gap helps to equalize humidity and reduce condensation - a hash board killer.
Looking forward for the 3d file if you can get with your friend.

No problem, let me ask my friend.

Very nice! I too am using the 6 inchers, on both sides though. I'm in the middle of building a Small room in my basement,
where I will draw in cool air from outside, and vent the heat into my HVAC system. In the warmer months, I will draw in the
cool basement air, and vent the HOT air out a window. On a 90 degree F day, the basement is about 65 degrees F.
Have you ,or do you, use any type of dust filter?

I am not using any filters, this is all set up in my garage so the air intake is simply inside and fairly clean. From there it is blowing in to a 3-sided carport. Long term I plan on converting a small 20' X 4' (skinny rectangle) storage room for the miners I keep at home. The thin long room looks to be a perfect setup, it's at the back of my lot well away from neighbors so I can run some large CFM exhaust fans to draw airflow over the miners. In that setup I will definitely run filters built in to the wall opposite the exhaust fans.

Can you give a more general idea of what you're doing with this? Is it just for sound or are you drawing outside air?
Me? I am just getting rid of waste heat.

I have 25 miners running in my house - I found on the outlet side a 6" flex duct goes nicely over the end of the miner with no reducer. The duct can be up to 8' w/o causing back pressure. On the inlet side I use 4" flex and leave a 1" gap away from the miners - to mix in room temp air. The differential between inlet & outlet temps can form condensation on the hash boards.
