I'm about half way thru a studio project, situated in an industrial building w/ concrete floor and drywall (gypsum board) in walls and ceiling.
So far we've made three separated floating floors, 45x95 mm wooden frame, 95 mm rock wool and two layers 22 mm tounge/groove particle board, floated on 40 mm thick plastic/rubber foam (kind of "ground sheet-ish"?). Separated from the floating floors is a hallway wall, w/ two leafs of 13 mm gypsum board isolated w/ 45 mm r/w. The rehearsal room to the left on the (not to scale) floor plan below is finished, walls made of 13 mm g/b and 95 mm r/wl in steel studs and two final 13 mm g/b, ceiling 45 mm r/w and two 13 mm g/b, and already in use with quite satisfying STC results.
Unfortunately there isn't a very high ceiling in this place and the concrete floor is not at all level, so we ended up with a maximum height of 2,38 meters (inside measures) for the studio and somewhat more for the control room
Anyhow, we just started the framing for the studio and due to my claustrofobic partners I think we'll be using the same construction method as for the rehearsal room and have that "disgusting" parallell wall thing
, however, I calculated the modes and don't see any major problem frequencys (but who am I to judge?). The rehearsal room is used by another band anyway, so the studio will also be used for our practising needs. Probably we'll use mobile baffles and also some kind of variable acoustic treatments to make things work also in "non electrified" situations. The control room will have a large (150x100 cm) window centered in the front end so the soffit for the Genelec 1032A's has to be angled at slightly wider angle, ca 66 deg at mixing position, to keep the sweet spot away from the rear. They will also be mounted rather high, 120-130 cm, to keep the near-fields out of the path, so it has to be tilted 7-8 deg. Would it be a good idea to slant the soffit all the way to the floor to avoid an angle just below the monitors?
I've been playing around trying to get the most out of the control room and so far theese two ideas seem to point out the direction...
Note that this is just some playing-around stuff and not considered final designs.
It also would be nice to be able to perform some mixing when there's a thrash-metal band rehearsing next door, but nothing we take for granted, just hoping for it to happen. Are there any ways of assuring this, to add some extra dB to the STC?
Any thoughts or questions on this design are welcome and I appologise my first post being so long (and full of errors, english is not my first language)
) so I guess I'm not that bad, however, some of the technical terms might be confusing, since everything has different names in different countries...
