I've finally cleared out the room that is going to become my home cinema and I've got a bit of a problem, acoustics wise. It's 16'x15'6", low ceiling, in the basement with 18" thick walls to either of the neighbours so I guess that soundproofing isn't too much of an issue. At the moment the floor is tiled and it has a strange hi pitched reverberating echo (not quite sure how to describe it, but it sounds odd). All the walls are brick. I'd like to canvass some opinions on what to do. I was thinking of doing the room in a room thing, but I guess it's overkill and I'll loose a lot of space (particually height). I plan on soundproofing the ceiling by either blowing or laying insulation between the joists and adding a layer of plasterboard and green glue to the ceiling, plus I'm going to add another door on the outside of the door frame and seal the gaps (the internal walls are 10" thick so there's a nice airgap there. My wife wants a suspended ceiling that doesn't reach all the way to the edge of the room. The gap will then be illuminated - sounds odd but we a friend's flat had it done (minus the lighting) and it looked great. I'm getting pushed to lay a wooden floor, although we'll put rugs on it. I'm planning on making acoustic panels to line the side walls (btw. does anyone know where to get suede effect material that's acoutically transparent - microfibre?) and am thinking of putting skylines on the back - partially for acoustics, partially because the look cool. Anyway a few questions, I have the option of having a plastered or fabric ceiling, If I go for fabric I can put sound absorbing material beneath it - will this be of any benefit. I wasn't planning to deaden the wall behing the screen, mainly because I want to limit the number of panels I have to make - will this couse me problems? Would it be better if I did? Anything else I should do? Anything here I shouldn't?
