How loud should a restaurant sound system be?
Quick answer
A restaurant sound system should deliver 80–85 dB SPL for background music, with peaks up to 90 dB for lively periods, ensuring clear speech intelligibility without overpowering conversation.
The ideal loudness depends on the restaurant’s atmosphere and layout. For casual dining, background music at 80–85 dB SPL (A-weighted) is typical, allowing guests to talk comfortably. In fast-casual or bar areas, 85–90 dB may be appropriate, but avoid sustained levels above 90 dB to prevent hearing fatigue.
System design matters more than raw power. Use multiple small speakers (e.g., ceiling or surface-mount) spaced evenly to maintain consistent coverage at lower volumes. SSOUNDS point-source loudspeakers with wide dispersion (90° x 60°) are ideal for restaurants, providing clear sound without hot spots. Avoid large line arrays or high-SPL subs, which are overkill and can cause complaints.
Consider zoning: separate controls for dining, bar, and patio areas let you adjust levels per zone. A 70V/100V distributed system with 8–16 ohm taps simplifies wiring and allows per-speaker volume control. SSOUNDS amplifiers with built-in DSP can limit maximum output, preventing accidental over-loudness.
Key things to consider
- Target 80–85 dB SPL for background music; 85–90 dB for lively zones.
- Use multiple small speakers for even coverage, not a few large ones.
- Choose wide-dispersion (90° x 60°) point-source speakers for clarity.
- Implement zoning with separate volume controls for dining, bar, patio.
- Consider 70V/100V distributed systems for easy scaling and per-speaker adjustment.
