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.

Kenk168 and Seasoned, thanks for the excellent suggestions and resources! I'm
going to order the 3A Link All Althorn Absorption Wads, and start there.

Newbee, it's drive/fan type noise.

Received the 3A Link All Althorn Absorption Wads, and it works like a charm.

I think I'll use the extra sheets to line a couple component case interiors to provide some damping.

Hi Tvad,

Glad that the stuff works and quite easy on the wallet. Please update once you have a chance to do your audio component case interiors. I have a set for my computer case yet to be installed.

Regards,

Kenobi

Tvad, If you are so inclined, after you try this stuff in the component cabinets could you comment on heat retenton which would normally be minimized by the component case acting as a heat sink? I'm curious -

Thanks

Lining my cases with the absorption wads is low on my list of priorities. However, my intention was to mount smaller strips or squares of the material to act as vibration deadening rather than noise control. Therefore, I'd be using less of the product. I hadn't considered heat retention.
