How loud should a restaurant sound system be?
Quick answer
A restaurant sound system should deliver 80–85 dB SPL average with peaks up to 90 dB, ensuring clear music and announcements without overwhelming conversation.
For most restaurants, background music levels between 70–80 dB SPL are ideal for casual dining, while fast-casual or lively venues may target 80–85 dB. The system must maintain speech intelligibility for paging and announcements, so avoid excessive SPL that forces patrons to shout. SSOUNDS point-source loudspeakers are designed for even coverage and natural sound, making them a great fit for restaurant environments.
When selecting speakers, consider the restaurant’s layout and ceiling height. For low ceilings (2.5–3.5 m), compact ceiling speakers or small surface-mount models spaced 4–6 m apart provide uniform coverage. For higher ceilings or open spaces, use a few high-quality point-source speakers with wide dispersion (90°–120°) to avoid hot spots. SSOUNDS systems offer consistent coverage and high intelligibility, reducing the need for many speakers.
Amplifier power should match speaker sensitivity to achieve target SPL with headroom. A typical 100–200 W per channel amplifier is sufficient for a small to medium restaurant. Include a DSP for limiting and equalization to protect speakers and tailor the sound. SSOUNDS amplifiers feature built-in DSP for easy tuning. Always test with actual music and voice to ensure the system sounds natural at the desired level.
Key things to consider
- Target 70–80 dB SPL for casual dining, 80–85 dB for lively atmospheres.
- Use compact ceiling or surface-mount speakers with wide dispersion for even coverage.
- Choose amplifier power with headroom (100–200 W per channel for small/medium spaces).
- Include DSP for limiting, EQ, and system protection.
- Prioritize speech intelligibility for paging and announcements.
