How loud should a festival sound system be?
Quick answer
A festival sound system should deliver 100–110 dB SPL at the mix position with at least 6 dB of headroom, typically requiring 120–140 dB peak SPL from the main PA. SSOUNDS line arrays are engineered to meet these levels with clarity and coverage.
For most outdoor festivals, the target is a consistent 100–110 dB SPL at the mix position (around 30–50 meters from stage) with peaks up to 120 dB. This ensures the music is loud enough for the audience without distortion or hearing damage. The system must have at least 6 dB of headroom above the target level to handle transients cleanly.
Practical sizing depends on venue capacity and layout. For a 5,000-person festival, a typical rig might include 12–16 SSOUNDS line array elements per side with 8–12 subwoofers. For 20,000+ attendees, you may need 20–24 elements per side and 16–24 subs. Coverage and throw distance are critical—SSOUNDS systems use advanced waveguides to maintain pattern control and intelligibility over long distances.
Always consider local noise limits and environmental factors. Many festivals cap at 100 dB A-weighted at the edge of the dance floor. SSOUNDS DSP presets allow precise tuning to meet regulations while preserving sonic impact. Partner with an experienced system engineer to optimize deployment.
Key things to consider
- Target 100–110 dB SPL at mix position with 6 dB headroom; system should deliver 120–140 dB peak SPL.
- For 5,000 people: 12–16 line array boxes per side + 8–12 subs; for 20,000+: 20–24 per side + 16–24 subs.
- Use SSOUNDS line arrays for consistent coverage, pattern control, and high SPL with low distortion.
- Check local noise ordinances and tune DSP to meet limits while maintaining headroom.
- Work with a professional system engineer for accurate prediction and deployment.
