Does anyone use wood for vibration control?

What kind of wood have you found to be best?

I built a custom rack with wood shelves using a vintage, heavy and stable welded iron frame I found at auction. The supporting brackets are simple 90 degree L bars welded to corner verticals. I needed to isolate all three shelves from direct contact with the iron frame which had a small but perceptible harmonic when hit.

The shelves are a layered concept consisting of a bottom layer of 3/4 inch Baltic plywood with an upper layer of 1 inch (finished thickness) tiger maple. The edges of the plywood cannot be seen as it is recessed into the L bars.

The two layers are isolated from the frame and from each other with Fat Dots from Herbie's Audio Lab. The decoupling is near perfect and there is little to no transmission of vibration to the maple. By using this "sandwich" design with two discrete layers of isolating/decoupling material I seem to have  eliminated the need for using 2+ inch wood stock.

Other than having to cover most of what is great looking tiger maple with equipment, I am super pleased with the results. The experiment paid off well.
