I have 3 DIY created rooms in my large live/work studio/artist loft. They are made with 2x4 and 2x6, framing with drywall walls and plywood ceiling.
The apt has 14' 7" ceilings so we just have enough room for the 6' tall upper level. I'm currently framing in these upper walls. The hope is that I can turn this upper space into a great little music studio with drum kit, amps, keyboards, etc.
How can I best insulate this space so that it's quiter than it is now for my roommates (I have the drums up there already :-) ) and its especially quite for my neighbors. The apt walls are mostly drywall Side to side between concrete pillars and the floors and ceilings are both concrete.
Also, per the buildings charter (supposedly, at least) I have complete lee way to construct within the space.
Plan is now to buy some large foam and put the amps on blankets per this question
