Hey Folks-
I just finished building a number of new rehearsal studios at my facility. I had originally spec'd heavy, solid core exterior doors in equally solid wood frames. Unfortunately, at some point in the project, the city demanded that my lovely open hallways (with 20 ft ceilings and skylights) be covered to make a 1 hour rated fire exit. With the hallway in place, I was also no longer allowed to use the wood door frames, and had to use fire rated metal ones.
I find myself dealing with one of those "weakest link" moments. We used double stud construction, multiple layers of sheetrock, caulk, etc., and the sound transmission from room to room is damn good. The hallways, however, are horribly loud, due (I believe) to these hollow metal door frames. The contractor did backfill the frames with fiberglass, but I'm wondering if there is anything else I can do to quiet these assemblies down, or if I am going to have to rip out all of the frames and re-install the doors with proper, solid wood ones. It would be a heck of a lot of work, and I may be circumventing code, which I am not anxious to do.
Any thoughts would be greatly appreciated!
Cheers,
Ryan
