Sound absorption panels for unside stand??

[kwirky]

i've used them in computers. Don't bother, I think. Our pumps produce similar noise signatures to computer fans and that noise proofing doesn't solve it. It only made computer cases super heavy.

kwirky, was it the fiber glass panels or the cellulose type?

i use celfort. the hard pink styrofoam from revy or windsor. it comes in 2+8 sheets. works decent

is your outlest pipe submerged into your sump? that may help

Ian, Ya both pipes are submerged. My setup is one drain from Tank, into two sump lines. One at each end of the sump. Skimmer>pump<Refugeum Is my plan, but dont think I'll have enough room in 10g sump. Quite a bit of air comes down the Durso drain. I have small air holes drilled into the top of the Durso too, 6 .045" holes. Just enough to stop the water in the overflow from surging. Most my noise is from Durso gurgling too.

i've used DynaMat. It's like a compressed tar material. Didn't work on computers very well.

Dynamat is more for deep, low frequency sounds. Not fans and Pumps. I have installed many pounds of Dynamat in my vehicles
