I'm looking to cut down on impact sounds and some radio noise from above.

I think the room is small enough (less than 5 feet) that I frame a drop ceiling from lumber that is decoupled from the above joists and only connected to the walls with 2X4s.

I think I could even double rock this with a green glue sandwich without weight or saffing issues, is this the most reasonable approach to a small room where suspended channels and such are a little overkill? I think this method limis the sound I'll get to flanking noise, is that about right?


Thanks,

Scott

Well you would get some reduction, just remember to insulate the cavity you create do not leave it empty.

Ok I'll get some insulation as well, what's the most effective for use in joist cavities then?

Is my desgn sound?, utilizing a drop ceiling construction of 2X4, it's perimeter frame tied to the walls and new 2X4 ceiling joists connected to this perimeter frame? I'd rock it twice with green glue between layers and hold the drywall a 1/4 away from the wall.

I'm a little fuzzy on the Double Tripple leaf thing, I do have an exising dry wall ceiling in this room. It has two holes currently in it that once were vents. I'm assuming they can stay, and hopefull also that they avoid the tripple leaf by not enclosing the air into the original ceiling/joist space.

Have I got that correct?

We like cotton fiber insulation from bonded logic.

Your design has a few flaws but will yield some reduction, you are still hard mounting so leaving the 1/4" gap is not necessary.

It would be better to remove the center leaf or put more holes in to open the air space.

Give me a call direct and we can get into details.
