Odd question: Would it be possible to build a usable room where you can have two mixing positions? One for music and TV, where the mix position would be a third in the room from the front and one actually a third from the back, using LCR behind a perforated screen and surrounds on the wall (mini dubstage for premixing cinema). ANY thoughts on construction and treatment appreciated!
For acoustic treatment I recommend something that not have different front and back treatment like MyRoom Design. Basic principles are that you need to have a heavy LF wideband apsorption treatment at all surfaces excluding floor, and also air transparent diffusion over all absorption surfaces. Less expensive version may be without air transparent diffusers based on Schroeder formula, but with binary diffusers over LF absorption treatment.
Any layman reading regarding the Schroeder formula?
How long did it take to treat the room and cost per m2?
What do you mean by the binary diffusors?
The Schroeder Quadratic-Residue Diffusor: Design Theory and Application , P. D'Antonio, J. Konnert, 74th AES Convention, New York, 1983.
Also we don't have our workers, we are a designers only.
We usually do three different layers of treatment, basic wooden frame next to wall, with first layer of absorption (surface dependent), Hidley/Newell panels in the middle (volume dependent) and diffusion layer with his wooden frame (surface dependent), in front of all this.
3a. QRD based air transparent diffuser costs about 80EUR/m2 for very basic version (lacquered OSB) with frame for supporting and some aesthetic (wooden) covering for it... using veneered particle board for building diffusers is better but it is more expensive and price depends also on type of veneer and finishing.
3b. For binary diffusion with slats built from fir or linden/tilia (real wood) costs about 30EUR/m2 with frame for supporting, some fabric, lacquering and some aesthetic wooden covering.
In price isn't included labor, design and support, but I hope that you can build some picture about costs.
All listed here didn't include spending room volume, money and time for sound and vibration isolation. Only acoustical treatment is described.
When I wrote "binary diffuser" I mean amplitude grating diffusion structure where absorption and reflection regions alternate following random or pseudo-random binary sequence where "0" may be absorption and "1" reflection. Structure may be one dimensional or two dimensional. One of two dimensional structures is commercial product called BAD panel from RPG Inc (patent).
Can bamboo wall treatment help dead room?
