| RT60 and acoustic modeling
Wes Lachot ran the Sabine equations to determine that the room will have an RT60 that can be varied from 1 full second down to 1/2 second. The room is tunable via the 10 large (11' tall, 2' wide) diffusors/absorbers that will be fabricated from RPG FlutterFree-T material. Wes has spent many hours with the folks at RPG to really tune the room for a maximum balance of diffusion, absorption, and overall wonderfulness.
Another major acoustic element in the Music Room is the cloud: it will be fabricated with 30 panels of fabric over fiberglass and 30 panels of RPG BAD panels (custom fabricated to a rhomboidal rathern than rectangular shape). These 60 panels will fit 1680 sq ft of surface area into 780 sq ft of ceiling area. There are two tricks to this: (1) both sides of the cloud have acoustic properties, and (2) the cloud is articulated in 3 dimensions, giving us more than 14 sq ft per panel in 13 sq ft of 2-dimensional ceiling space. This articulation will provide additional diffusion of low frequencies to complement the diffusion of the BAD panels.
