The part of my tracking room where my mics live looks
about like this:

The part where I live, looks about like three of these:

joined in a 1/2 hexagon.

I hang 2' X 4' laminations of 2.5" foam (from here:

layered with this:

in the center, and this:

in between, for a total thickness of about 5.5".

For looks, mostly, I slip the laminated 2' x 4'
pieces in these:

I sit with the 1/2 hex wrapped around behind me,
and the mic enclosure in front.

I can record with a window air conditioner running,
six feet away, with no detectable noise recorded.
