In the following pic, it is hard to see, but the ceiling of the building is about 20 feet or so above that AC duct. You can see the metal studs on the right side of the pic. They end just below that duct.
The ceiling of our two rooms will be about 4 feet and 2 feet below that where the metal studs end.
The problem is this:
It is next to impossible to build a barrier the can be completely sealed from sound coming from the other rooms and the street noise ABOVE our studio ceiling and those ducts. In other words, except for drop ceilings in all the other rooms of this commercial building the ceilings are wide open!
Of course the ceiling of our rooms will be double dry walled and sealed air tight.
Questions:
Might the one leaf ceilings of our studio room ceilings be enough to stop sounds coming from the other rooms from above?
We CAN build a barier that has 2' gaps all around. Is a barier with gaps like that worthless?
Any other ideas and thoughts about what we can do?
Help Kendale, or anyone!

Aloha,
Have you taken any measurements to see how many dB's you need to block? This may be frequency dependent.Might the one leaf ceilings of our studio room ceilings be enough to stop sounds coming from the other rooms from above?
I'm not sure what you are describing here. Can you do a quick sketchup to clarify? Aloha 8)We CAN build a barier that has 2' gaps all around. Is a barier with gaps like that worthless?
No. But, I thought of something. If you can see in the pic the frame for the drop ceiling that is there. (Should be a beige color.)We can cut squares of 5/8 gypsum and seal them in. Each one of those squares has a rim. If we caulk the perimiter of the rim and drop a peice of gypsum cut to fit in each one then caulk more around for insurance, then maybe that will work. Then we can glue some insulation or some acustical foam to the bottom. That frame goes completely across both our rooms on top and can be completely sealed. What do you think about that? I hung on those things yesterday with all my weight. They are very stong and I believe they will support the weight of the drywall.Have you taken any measurements to see how many dB's you need to block? This may be frequency dependent.
