just did the stomp test on the wood floor - they're covered with a thick pad and wall to wall carpet so the hollow sound is not so bad, especially compared to stomping on the kitchen floor w/ no carpet. What I noticed more in the carpeted room were little shakes from items on the end tables. The floors have 18" of crawlspace underneath and are supported by 4'on center 4x6 joists covered with 2x6 fir and then with 1/4" oak hardwood. I am doomed?
