Quieting a dehumidifier
« on: July 26, 2009, 04:50:21 AM »
I have a rather loud dehumidifier in my basement that runs most of the time in the summer. As a small test project for other more substantial projects, I'd love to find the best way to reduce the noise level.

The dehumidifier sits on the concrete floor of the basement. Not sure what other information might help...

Maybe putting a mat underneath (but I'm not sure there is much sound transferred through the concrete floor)?
Maybe put some MLV on the floor just around the dehumidifier?

Putting MLV on the floor under the unit will not help reduce the noise from the unit. Try using a sound blanket over the unit leaving the vents open. Or you can adhere SSP Foam mat to the unit, these will only be a slight reduction due to the fact air is still moving.
