Treatment Summary
| Room | Panels | Bass Traps | QRD | Curtain | [AC] Required? |
|---|---|---|---|---|---|
| VO Live B304 | 8 | 4 | 0 | 1 motorized | Yes — NC-12 target |
| Control Room B311 | 2 | 4 | 2 | — | Yes — first-reflection |
| Video Studio B312-1 | 13 | 4 | 2 | — | Yes — RT60 target |
| Editing Suite B312-2 | 4 | 2 | 0 | — | 4 [AC] |
| TOTALS | 31 + 4 QRD = 35 | 14 | 4 | 1 | Order: 38 (10% waste) |
[AC] Acoustic Critical — Editing Suite RT60 without panels = 0.42s, failing the 0.36s target. These 4 panels must be installed before commissioning sign-off.
Panel count logic: 27 required (8 VO + 2 CR + 13 ST + 4 ED) + 4 spares = 31 absorption panels + 4 QRD diffusers = 35 total panels. Order 38 (35 + 10% waste buffer).
Must be removable for electrical access behind panels
