I have one of these portable air conditioners with a 3D printed intake cover for a second hose and it works fairly well in terms of cooling but it is quite noisy. I was planning on constructing a frame from scrap wood or cardboard and place some kind of sound insulating material around the AC, with possibly a second layer and an air gap in-between. What would be a good and affordable material for this kind of purpose and do you have any other tips to reduce the noise? I read that some have used mineral wool, fiberglass, acoustic panels or even towels.



Also, I might try to insulate the hoses with aluminium foil and towels as I read that it might help somewhat with the efficiency of the AC. Perhaps it would be best to just buy an already insulated hose.

Bubble wrap is better.

For sound heavy is better, I would use Melanie for the frame and some heavy old rug inside to deaden the ecco. As for insulation for the hoses, bouble wrap works the best. Combine with one of those cheap artificial fleece blankets for near perfect insulation.

I think I will not use melanime since it's easier to just get some scrap MDF from my university's workkshop since I will be making this there and avoid carrying that back and forth. As for the rug, I don't have anything like that thicker than a towel, which is why I'd like to buy some kind of foam/tile material. I will be using bubble wrap and fleece blankets for the hose though.

Yeah OP just cover it up, its a magical cold air producing machine, it doesn't need intake. And insulating the hoses will have a negligible effect. Kudos
