Enclosed is a file with a rough drawing of the treament I am thinking of for "sjoko's studio" tracking room roof.
Room dimensions: 31' long, 24" wide, 22" high, American Barn style with 20 degree angled walls.
For visual - see pictures on John Sayers' website: http://www.lis.net.au/~johnsay/
Room construction:
Floor to 3' height - 2' block and stone, concrete filled wall on concrete and rock foundation.
Floor, rebar reinforced 2' thick concrete poored within the walls - measured no resonance at any frequency. Side walls and roof (above the block / stone base wall), 2 x 6 Douglas Fir frame, 3/4" external siding. Frame filled with 6" Cocoon cellulose, closed off with 1/2" soundboard and 3/4" high density fire-rated drywall.
Rear wall, 2 x 4 external frame, 2 x 4 internal frame with 2" spacing between the frames. Internal wall "floating", resting on heavy duty neoprene strip, connected to rear wall and side frame by means of Samson galvinized steel strips.
Acoustics:
Measurements were undertaken prior to stripping the previous internal cladding, with the cladding removed, and in its current state, with walls filled with insulation and closed with soundboard. The room has a rarely found outstanding, natural sound and , due to its American barn shape, a very low level of standing waves. It also has a long, natural decay time. The decay cannot be measured accurately in its current state (soundboard), but is expected to increase once the drywall has been fitted.
Low frequency build-up was detected around the control room wall and in the corners of the rear wall. By the control room wall this will be counteracted by means of a 14' long, 4' deep and average 2' high (112 cubic feet) trap, with a top made from 2 1/4" thick straw batt, internally fitted with glasswool insulation sides and hanging panels. (basically it will look like a thatched roof). A rear wall - a small room will be build running diagonally from the loading-in door to the side wall, providing for a 2nd. loading-in door (air-lock) with next to it a small room for microphone and cable storage. This room will also have an angle straw roof with build in insulation and acoustic hangers.
Objectives:
The objectives for the room are to:
1) Create a live sounding room which lends itself to recording with a lot of natural ambiance. In other words, a room perfect for recording drums, percussion, grand piano, and other acoustic instruments.
2) Create a space where the ambiance of the room is controllable, from live with a long decay, to relatively dead with a short decay.
The means by which I plan to achieve this is described in the enclosed file. I would very much welcome your opinion and suggestions!! Gottagetitright!!!
Hey John? How do you manage to post drawings direct into this?????
