The Goal
A conference room must support clear speech and video calls. That means controlled reverberation (RT60), low background noise, and adequate insulation from adjacent spaces (see absorption vs insulation).
Design Elements
- Absorption — ceiling and upper-wall treatment to shorten reverberation and improve speech clarity.
- Insulation — well-sealed walls, doors and glazing to keep conversations private.
- Background noise — quiet HVAC and equipment (see HVAC noise control).
- Layout — position speakers and microphones away from noisy walls and reflections.
Practical Steps
- Treat the ceiling and the wall behind the screen first (first reflections).
- Use solid-core doors with seals (see Sound Insulation for Doors).
- Verify reverberation by measurement where practical.
Relevant Standards
- ISO 3382-2 — reverberation time in ordinary rooms.
- ISO 10140 / ISO 717-1 — insulation of walls/doors.
Limitations
Target values depend on room volume and use; set them per project and confirm by measurement. Absorption alone does not provide privacy — insulation and background-noise control matter too.

Frequently Asked Questions
Why does my conference room echo on video calls? Likely excessive reverberation; add absorptive treatment and confirm the RT60.
Do I need insulation or absorption? Usually both — absorption for clarity, insulation for privacy.
