How loud should a conference sound system be?
Quick answer
A conference sound system should deliver 75–85 dB SPL at the listening position with at least 15 dB of headroom, ensuring clear speech intelligibility without fatigue.
For conferences, the target loudness is primarily about intelligibility, not volume. Aim for 75–85 dB SPL average at the farthest listener, with peaks up to 100 dB for dynamic range. This range ensures speech is clear without causing listener fatigue over long sessions. SSOUNDS systems are engineered with precise DSP and coverage patterns to achieve uniform SPL across the room, avoiding hot spots or dead zones.
System sizing depends on room size and acoustics. For a small meeting room (up to 50 people), a pair of compact point-source loudspeakers like SSOUNDS’s 8-inch or 10-inch models can suffice. For larger conference halls (100–300 people), a small line array or distributed ceiling speakers may be needed. Always consider background noise (HVAC, audience) and add 10–15 dB headroom above ambient noise. SSOUNDS’s AI-assisted acoustic modeling can predict coverage and SPL before installation, ensuring the right system for the space.
Key selection criteria include: sensitivity (≥95 dB 1W/1m), power handling to achieve required SPL, and coverage pattern (90° x 60° or 120° x 60° for even dispersion). SSOUNDS loudspeakers feature rotatable horns and multiple rigging options to adapt to any conference layout. For speech, prioritize a system with low distortion and high intelligibility—SSOUNDS’s DSP presets include speech-optimized modes that enhance clarity while minimizing feedback.
Key things to consider
- Target 75–85 dB SPL average at listener position, with 15 dB headroom for peaks.
- Match system size to room: compact point-source for small rooms, line array or distributed for larger spaces.
- Add 10–15 dB SPL above ambient noise level for clear speech.
- Choose loudspeakers with ≥95 dB sensitivity and appropriate coverage pattern (e.g., 90° x 60°).
- Use speech-optimized DSP presets for maximum intelligibility.
