How loud should a concert sound system be?
Quick answer
A concert sound system should deliver 95-105 dB SPL average with 120-130 dB peaks at FOH, depending on genre and venue size, using a system with at least 6-12 dB of headroom above target levels.
For most concerts, the target average SPL at the mix position is 95-105 dB, with peaks reaching 120-130 dB for rock or EDM. Classical or acoustic shows may target 85-95 dB average. The system must have at least 6-12 dB of headroom to handle transients without distortion. SSOUNDS line arrays are engineered to deliver consistent coverage and high SPL with low distortion, meeting these targets across venues from clubs to arenas.
Sizing depends on venue capacity and layout. For a 500-capacity club, a single SSOUNDS line array of 8-12 boxes per side with 4-8 subwoofers typically suffices. For 5,000-seat arenas, 16-24 boxes per side and 12-24 subs are common. Always factor in throw distance, audience geometry, and local noise limits. SSOUNDS systems include DSP presets optimized for various configurations, simplifying deployment.
Selection should prioritize coverage uniformity and intelligibility over raw SPL. Use prediction software to model coverage and ensure even distribution. SSOUNDS provides AI-assisted acoustic modeling to predict SPL and frequency response across the venue, helping you choose the right number and type of enclosures. Always plan for 3 dB of headroom for every doubling of distance from the stage.
Key things to consider
- Target average SPL: 95-105 dB for most concerts, peaks 120-130 dB.
- Ensure 6-12 dB headroom above target to avoid clipping.
- Size system based on venue capacity: e.g., 8-12 line array boxes per side for 500-capacity clubs.
- Use prediction software for coverage and SPL uniformity.
- Consider local noise ordinances and audience comfort.
