Acoustic Doors & Window

Complete bill of materials for all acoustic doors and the observation window between Control Room and VO Live booth. Includes hardware, seals, and installation specifications.

BUILDER CUSTOMIZATION GUIDE — DOORS AND WINDOWS BOM

CUSTOMIZABLE — Door leaf surface finish (veneer, laminate, or paint colour) may reflect your branding or client preference. Handle/lever hardware style and finish are flexible provided the latch mechanism maintains the acoustic seal. Threshold cover plate finish may be customised. Door signage and room labels are at your discretion.

DO NOT ALTER — Door STC ratings (D1: STC 50, D2: STC 45, D3: STC 45, D4: STC 40), door dimensions (widths and heights as specified), perimeter seal type and compression specification, automatic door bottom drop-seal mechanism, frame construction (steel vs. timber as specified per door), core fill material and density, and observation window glass layup (6mm float + 100mm air + 10mm laminated + 75mm air + 8mm float). Each door STC is matched to its host wall — substituting a different assembly will create a flanking path.

Door Schedule

Acoustic Doors

Five acoustic doors with STC ratings matched to room isolation requirements. All doors are solid-core with perimeter acoustic seals and automatic drop seals.

Door Hardware

Hardware Per Door

Each acoustic door requires the following hardware set. Quantities shown are per door unless noted otherwise.

Observation Window

Triple-Pane Window

Control Room to VO Live observation window. Three panes at different thicknesses with asymmetric air gaps and 5-degree tilt to prevent standing waves and reflections.

Installation

Window Installation Notes

Critical Window Installation
  • Tilt direction: VO Live side (recording) panes tilt upward at 5 degrees. This prevents sound reflections back to the microphone and directs any reflections toward absorptive ceiling treatment.
  • Seal requirements: Continuous neoprene gasket around all pane edges. Frame-to-wall joint sealed with acoustic sealant (non-hardening type). No rigid contact between glass and frame (use EPDM setting blocks).
  • Condensation prevention: Air gaps must be sealed with desiccant breather strips. Use molecular sieve desiccant in bottom channel of each air gap. Install drain weeps at VO Live side base.
  • Asymmetric panes: Different glass thicknesses (6mm, 10mm, 8mm) are critical. Equal thicknesses cause resonance coincidence that degrades STC performance.
Isolation Strategy

Sound Lock Concept

Buffer Spine + Dual Door Sound Lock

The MediaVerse layout uses the central buffer spine partition wall for acoustic isolation between all acoustic rooms. No two critical rooms share a direct door; instead, each is accessed through the buffer zone.

Sound Lock Path - Plan Schematic
Entry STC 50 D1 Buffer Spine STC 55 walls Absorptive lining D2 Control NC-25 Editing NC-35 D3 D4 VO Live NC-20 Studio NC-25 Window STC 50
Sound Lock Principle

To reach any critical room (VO Live NC-20 or Studio NC-25), sound must pass through at least two acoustic doors with the absorptive buffer zone between them. This creates an effective combined isolation of STC 45 + STC 45 + buffer absorption = 70+ dB effective. The buffer spine walls (STC 55) provide lateral isolation between the north and south room pairs.
