Any thoughts on how to overcome the noise "bleed" problem.
Sound proofing relies on mass, air tightness and isolation - truely soundproof rooms cost a lot in part because of the air conditioning you need - to be sound proof it needs to be airtight, which can make other activities (such as breathing) complicated! ;-)
