VO Live Room

VO Live Room

The most acoustically critical space in the MediaVerse Studio Complex. Designed for professional voiceover, podcast production, Quran recitation, audiobook narration, and live acoustic recording with an NC-20 noise floor.

Use Cases & Applications

The VO Live Room is purpose-built for speech intelligibility and tonal accuracy. Its ultra-low noise floor (NC-20) and controlled RT60 (0.20s) make it suitable for the most demanding recording applications.

Floor Plan & Dimensions

Key Dimensions

Geometry Note

The VO Live Room occupies the NW quadrant of the MediaVerse zone. Its west boundary follows the concrete diagonal wall, creating a non-parallel wall geometry — a deliberate acoustic advantage. Parallel walls cause flutter echoes and standing waves at predictable frequencies; the angled west wall scatters reflections across a wider frequency range, reducing modal energy concentration. This is especially critical for voice recording where even small colorations are audible. The trapezoidal shape yields a true area of 5.12 m² (less than L×W = 6.31 m² for a rectangle).

Boundary Build-ups

Every boundary of the VO Live Room is engineered for maximum sound isolation. The room is bounded by two concrete exterior walls (STC 65), a CLD buffer partition wall (STC 55), and the partition to the Control Room (STC 53).

Silencer Run A & Airflow

Design Driver

The VO Live Room's NC-20 target is the tightest noise criterion in the complex. This room single-handedly drives the HVAC silencer specification — Silencer Run A must achieve 40 dB attenuation with a terminal velocity of 1.5 m/s.

Silencer Run A Specifications

Airflow Path

Supply: Main duct (300 x 200 mm) enters from west side of the duct band, passes through Silencer Run A (1500 mm), and terminates at a low-velocity diffuser positioned for laminar flow over the performer.

Return: Return air grille located at opposite wall, low on the wall to create gentle cross-flow without turbulence at the microphone position.

Face Velocity: 1.5 m/s maximum at diffuser face, ensuring NC contribution stays below NC-12.

Window Specifications

Design Detail

The panes are angled at 5 degrees and 8 degrees respectively to break internal reflections between glass surfaces. Non-parallel glass eliminates flutter echo within the window cavity. Dry air fill (no gas) simplifies maintenance while achieving STC 50.

Design Constraints

Locked

NC-20 is non-negotiable for professional voiceover. This noise criterion is required by broadcast standards and is the foundation of the VO Live Room's commercial viability. Any HVAC modification or adjacent noise source must be evaluated against this constraint.

Modal Note

First height mode at 62.4 Hz (2.75 m acoustic ceiling). The 9.1 Hz gap between the length mode (53.3 Hz) and height mode (62.4 Hz) provides adequate separation — no problematic coincidence exists. Four floor-to-ceiling corner bass traps are specified for general low-frequency control in this small room (volume 14.08 m³, Schroeder frequency ~238 Hz).

Info

Observation window provides visual contact without acoustic compromise. The triple-pane window (STC 50) between VO Live and Control Room enables line-of-sight communication between talent and engineer while maintaining the required isolation. Non-parallel glass angles eliminate inter-pane resonance.
