I have recently moved to a new 'two room' apartment which I guess was formerly a one room apartment that was that was split in two by a wall whose stability I cannot really vouch for. The main problem is that this wall features a doorway. This doorway connects the living room which has a very large window that lets in a lot of light to the bedroom. We have not intention to cover the living room window because we love the light there, but we want to darken the bedroom for sleep. This, which is our main concern, I guess could be solved by a curtain. Is there any we could also put something that attenuates sound a bit? How complicated is it to install a door?
Any alternatives, either helping with the sound or not, are highly welcome.
