jpm,
Thanks! It has been no fun as you know. Took a long time to find the problem, but that should be solved two ways now!
Pez,
Hard vinyl flooring has come a long way! It is hard strips installed like wood flooring.
I have been contacting SonitusUSA about their room acousitic treatments after hearing a local person that wrote his experience up for AudioXpress with them. Sounded great to me, so trying to get them, but not sure if they have installers in the local area. Still working on it.
Right now it is a giant echo chamber with the hard drywall install. Two 1.2in pieces grain oriented, glued and screwed to the free standing studs. Got to love 15in thick STC83 style walls!
Just got some area rugs to put in to help quiet it down until the acoustic treatments get installed one way or another.
