Bob, I hadn't thought about the mess wet tiles would be. I actually had the thing on a couple sheets of packing foam and it was still pretty loud. I hadn't thought of Dale's bungy cord idea either, but I think the cabinet idea is a dead issue.

Setting one inside anything is going to restrict air flow to the unit and therefore efficiency. Also the tiles may collect some of the moisture and come apart. The suspension idea sounds like one to consider, but balance would worry me. The other thing you can try is putting a rug or thick rubber mat under the unit on the table it's on already. The wheels are probably vibrating against the surface causeing the extra noise. Something to cushion the wheels will take a lot of the noise away. Maybe one of those anit fatigue mats everyone is selling now. ----- Original Message ----- From: William Stephan To: blindhandyman@yahoogroups.com Sent: Monday, October 27, 2008 9:59 PM Subject: [BlindHandyMan] An Acoustics question As those of you who have them will doubtless understand, dehumidifiers are infernally noisy. The table I have mine on is delaminating. I don't know if it got wet at some point, or if the dehumidifier's just vibrating it to death. In any case, my next adventure is going to be to build a replacement table. I'm almost done with the shop vac silencing cabinet, and as usual, I bought too much acoustical tile. So, the plan is to make a table with a floor, roof, and two sides, and line all four surfaces with acoustical (or is that just acoustic) tile in the hope it will quiet things down some. So, my question: If I just have the tile on the floor of this box, the dehumidifier will very quickly vibrate it's way through it, and the wheels will touch the tabletop. So, would it be better from an acoustics standpoint to remove the wheels and have the whole surface of the bottom of the unit setting on the acoustic tile, or should I put something like a piece of ΒΌ inch plywood under the wheels, it would most likely have to be the same size as the tabletop itself to keep from sinking. I know we have some folks who know way more than I about how sound actually travels, so I'll quit now and hope they give some suggestions/answers. Thanks in advance.
