As you can see it's a very modest studio space compared to most, measuring 20' x 12' externally and 18' x 10' now the soundproofing is in (with the outer leaf constructed from 44mm timbre). However we're currently a bit unsure of what to do with the floor. It's been suggested that we lay down squares of neoprene pads, with gaps between them, across the entire floor and then put down a layer of plywood then a sheet of rubber matting (5mm-9mm thick) and another layer of plywood before adding the final surface layer (which I'd like to ask about in a minute!). Does this sound right and if not what would be the best construction?
Interestingly, we've seen a lot of threads where people say not to use carpet to finish it (our original plan), but to go for a reflective material: wood if funds allow or linoleum etc if going for the cheaper option e.g. http://www.gearslutz.com/board/studio-building-acoustics/146717-wood-floor -carpet.html Quoting from that page:
Carpet typically absorbs high frequencies and some midrange, but does nothing for bass and lower midrange. Using carpet as an acoustic treatment, in most rooms, results in a room that is dull and boomy. Most of the time you need a thicker absorber such as 4-inch or, better, 6-inch fiberglass, or acoustic tile, and you can't walk around on either of those. Hence the general recommendation that you avoid carpet on the floor and use broadband absorbers elsewhere.
However, the room is small and the ceiling is low so would a reflective floor be right for this particular build? There will be an acoustic drum kit set-up in one corner and this is another factor that's got us thinking. Will the flooring need to be done differently to cope? Should we add a drum riser? Sorry for all the questions, I just don't want to make an error this far down the track!
