There is a set of glass doors between my room and my roommate. It's not ideal, but it's San Francisco - what can you do! I do, however, need a way to cover the doors so we can't see through them and, more importantly, somehow block sound from filtering through as much as possible. We put up light curtains so far and I was considering acoustic foam. Any thoughts?
I've spent a lot of time sound proofing walls. In your current set up there's not much you can do easily that will be effective without causing damage to the walls. Maybe remove the doors off the hinges and put up a piece of plywood with some insulation on one side and 2 layers of dense fabric curtains on each side (e.g 4 layers) may be the simplest. Sheet Lead over the plywood would also kill a lot of noise. It will never be remotely sound proof tho.
