Steve - I haven't bought that "full auto" screw gun yet. I'm still a ways off from sheetrockin'. The electrical and HVAC needs to be roughed in still. And the live room wall needs to be framed up. There's also a little closet that for storage that I haven't started yet. That'll end up being part of the live room wall... and insulation needs to be placed, and... and... and...
There's SO much to be done! I spent the last day and a half hauling construction debris off to the dump! Five pick-up loads worth! It got to the point where I was moving junk from one room to another. And my yard, although hidden from any neighbors, had crap stacked up against the fence knee deep! That was REAL hard for me to deal with, because I have this "park-like" back yard. At least, I used to, before it turned into a construction site.
So, time to step back, clean up and re-group.
Re.: The walls. Fair enough.
Maybe I'm missing something though:
The staggered stud wall, with triple leaves gives an STC of 61. The double wall with triple leaves gives an STC of 63. ??
But you DO bring up a really valid point. And that is, Just HOW MUCH isolation do you need? For ANYONE contemplating ground-up studio construction, you have to answer this question before you even begin design. You could guess (not a good idea) or go with something that SEEMS reasonable (still not a real good idea) or, you could chart the noise on your site before you begin. Rent a dB meter, make sure its calibrated, and take measurements at regular intervals for a period of at least a couple of weeks. Graph the results, look for a high mean, and use that as a basis for your design.
The complexity of construction that I spoke of earlier... I forgot to mention that if your walls are not perpendicular to the trusses, which, unless they are exterior walls, they wont be, then you'll have a compound mitre at the top of the wall if you have a vaulted ceiling. Difficult to frame up unless you know what you're doing!
I JUST heard from my supplier. My front exterior door will be delivered tomorrow!!!!
Of course its a raw door and it'll have to be stained and well oiled, but, hey, its on its way!
