How loud should a stadium sound system be?

For stadiums, the target loudness depends on the venue size and ambient noise. Typically, you need 100-105 dB SPL continuous at the listening positions, with peaks up to 110-115 dB for impact. This ensures the system can overcome crowd noise (often 85-95 dB) and provide clear announcements and music.

Coverage uniformity is critical: the difference between the loudest and quietest seats should be no more than 6 dB. This requires a distributed system of line arrays or multiple point-source clusters, carefully aimed and delayed. SSOUNDS line arrays are designed for long throw and even coverage, reducing hot spots and dead zones.

Headroom is essential: the system should be capable of 6-10 dB above the target continuous level to handle transient peaks without distortion. For a large stadium (50,000+ seats), this might mean a total system power of 100,000-500,000 watts, but SPL and coverage are more important than raw wattage. Proper system design with DSP and amplifier matching ensures clean output.

Intelligibility is as important as loudness. Use the Speech Transmission Index (STI) target of 0.5 or higher. This requires careful speaker placement, delay towers for distant seating, and acoustic treatment if needed. SSOUNDS systems include advanced DSP for alignment and EQ to maximize clarity.
