for best isolation consider two very heavy doors....the gap in between the
doors will greatly help to reduce the sound especially if the walls they are
attached to are designed for acoustic isolation. This is the same principle
as using two sets of walls with staggered studs to reduce sympathetic
vibration....good luck!!

the second question i had on the iso booth was the door.

i know there is a brand of door that is "the one" to get for sound-lock
purposes.

but i'm looking for something that isn't 350 pounds and doesn't cost
$900.

i'd almost be tempted to use a double-paned sliding glass door if i
could find one that wansn't too huge and had awesome "suction" on the
seals when you close it (preferably making some sort of star trek
"schhhhwit" sound when it closes fully).
