Sound Insulation


I'm considering purchasing some material to mask some mechanical noise from a component in my rack.

I was considering 3/8" ultra-soft polyurethane (sorbothane) sheet, or perhaps some flexible polyimide, or flexible polyurethane (all sold at McMaster.com).

Other ideas?

Heat is not an issue. I only require about a 12"x12" piece.

Hi Tivad,

Here's another alternative from Monoprice: http://www.monoprice.com/products/search.asp?keyword=2364

You should be able to find something from here:

Tvad, Why not put some flesh on your question?

What is the noise source?
What kind of component?
How do you percieve using the materiel? Just as a pad between the component and the shelf. To enclose the component? To line a cabinet/box? etc.

BTW, if it is transformer hum, and the component sits of a shelf in the open, I have gotten little relief from putting sound absorbent materiel between the component and the shelf. I've used heavy dense sound aborbing foam as well as sorbothane. I always got the best benefit from damping the transformer itself.

FWIW.
