Ok guys, my flat refub is nearly finished and I just have one last project to complete.
This project is a soundproof bed.
This might sound a bit crazy, but my flat is in a basement (windows at ground floor level), next to a nightclub, just off a main road, in an area of pubs and bars. I would struggle to think of a location that has more noise problems! I have everything from low bass from the nightclub though cars screaming past, to people singing.
It was never my intention to soundproof my whole flat, I don't care about the noise at any time other than when I need to sleep, so I always intended to basically make a soundproof booth for my bed to fit into and that time is now.
I've studied hard on soundproof booth construction, and I think I have a plan that makes sense. However it will cost me about £3k to build this thing, including all the materials, and I'd like it to work. So if any soundproof experts could give my plan the once over I'd be most grateful.
Below is a very rubbish diagram (I'm not draftsman) that is not to scale but is close enough to get the idea of what I'm going to build.
As you can see, my bed fits flush inside this box. I access it from the big opening window at the foot of the bed.
Now, this box will be free standing in my bedroom, built on a decoupled base, and not attached to the walls of the room in any way.
Because of this, am I right in thinking that I do not need to decouple again (other than the base), by using resilient channel or isolation clips and furing? My research tells me that because I'm basically building a room within a room, my main priority should be trying to lower the resonance of my walls and the best way to do that is with absorption and mass. Basically I should not decouple again (other than the base). Is that right?
My plan is to build the walls (and ceiling structure) in the following way (left is outermost layer then move inwards toward the right):
15mm gyproc > 3" stud wall + 3" rockwool > 15mm gyprocc > Green Glue>15mm gyprocc
For the base (read from bottom to top)
18mm ply
Green Glue
18mm ply
Geniemat RST10
18mm ply
3" stud frame + 3" rockwool
Geniemat RST10
Original bedroom floor (laminate on concrete)
Will this base be sufficient to decouple the structure that it is supporting? Is there anything I could/should do to improve it?
The side windows are non-opening and are there so that I can see when it's morning, and for aesthetics, a sealed box would look even more ridiculous than this. The windows will be made from laminated acoustic glass, the outer panel 12mm thick, the inner one 8mm thick. Each pane will have about 80mm of separation.
The big window at the end will need to open for me to get in and out of bed. I'm having a 'soundproof' double glazed unit made at horrendous cost, probably 8mm and 10mm laminated panes. This window is also in this place specifically, as I have a wall mounted tv and sound bar that I will be able to watch from in bed when the window is open.
The weird staggered wall arrangement at the head of the bed is there due to my existing semi-dropped ceiling that I have made to house my LED tape that lights the bedroom.
The extra box on the top is the diffuser box for the ventilation, I'm going for a push/pull arrangement with a pair of 4" whisper quest fans drawn through home made diffusers. If I have to air-con it in the summer I will, but my flat is literally underground, so the temperature is normally very stable and as long as I get air moving though the box I think it'll be fine.
The inside/underside of the ceiling, that you will see when looking up from the bed when lay down, will be a fibre optic star ceiling.
I'm going to get cracking on this next week so I'll post pics of my progress. Shouldn't take me long.
If anyone thinks a better base or wall structure would help with isolation please, please, let me know.
