Hello,
Does anyone have any suggestions on limiting sound transmission through suspended ceilings?
I really have two questions:
A) in a commercial setup where there is suspended ceiling in use (which means offices are just big cubicles in the building shell capped off with suspended ceiling) how do you keep noise from traveling out of a noisy room? The suspended ceiling does little to stop the noise from exiting through the ceiling and because there are no walls seperating the offices above the suspended ceiling, the noise migrates down into adjacent rooms.
B) in same scenario outlined above, if you can't stop the noise at the source can you add something to the suspended ceiling in adjacent rooms to limit migration of noise into them through the suspended ceiling?
For A) I'm wondering if I can't hang egg shell foam sheets above the walls (in plane) maybe mass loaded with carpet padding affixed to it. I don't even no how that would hold up with fire codes. I have no idea what fire codes would be like above the suspended ceiling, whether there are limitations as to what you can put above them.
For A) I'm considering rolling out insulation over top of ceiling, possibly egg shell foam properly fire rated (and I'd make sure I was allowed to do so by code). Again, I wonder if 'mass loading' with carpet padding might help? (And again, of course there's the fire code allowances to do so.
