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 primary goal is speech intelligibility, not high SPL. A typical target is 75–85 dB SPL average at the farthest listener, with peaks up to 95–100 dB for emphasis. This range ensures everyone hears clearly without straining or feeling overwhelmed. SSOUNDS systems are engineered with precise coverage and DSP presets to maintain consistent levels across the room, avoiding hot spots or dead zones.

When selecting a system, consider room size, ceiling height, and acoustics. For small boardrooms (up to 50 people), compact point-source speakers like SSOUNDS’s installation series provide even coverage. For larger conference halls (100–300+ people), a distributed system with multiple smaller speakers or a line array with narrow vertical dispersion minimizes reflections. SSOUNDS’s AI-assisted acoustic modeling can predict coverage and optimize placement before installation.

Headroom is critical: choose amplifiers with at least 15 dB of headroom above average SPL to handle transient peaks without distortion. SSOUNDS amplifiers and DSP include limiter presets that protect speakers while maintaining clarity. Also, prioritize systems with speech-focused processing (e.g., automatic gain control, feedback suppression) to adapt to different presenters and room dynamics.

Key things to consider

  • Target 75–85 dB SPL average at listener positions; peaks up to 95–100 dB.
  • Use distributed speakers or line arrays for even coverage in larger rooms.
  • Ensure 15 dB headroom in amplification to avoid distortion on transients.
  • Select systems with speech-optimized DSP (AGC, feedback suppression).
  • Model acoustics with AI tools to predict and optimize system placement.
