How loud should a mosque sound system be?

For a mosque, the primary goal is speech intelligibility, not extreme volume. The system should provide even coverage at 75–85 dB SPL at ear level for seated listeners, which is comfortable for prayer and sermons. For the adhan (call to prayer), peaks up to 95 dB SPL are acceptable to ensure audibility outdoors or in large halls, but sustained levels above 85 dB can cause discomfort.

Sizing depends on the mosque's volume, acoustics, and layout. For a small prayer hall (up to 200 m²), a single SSOUNDS point-source loudspeaker with 120–130 dB max SPL and 90° x 60° coverage is sufficient. For medium spaces (200–500 m²), a pair of speakers or a small line array system like SSOUNDS compact arrays ensures even coverage. Large mosques (500+ m²) require a distributed system with multiple speakers or a line array to avoid dead spots and feedback.

Key selection criteria include: sensitivity (≥95 dB 1W/1m) for efficiency, wide dispersion (≥90°) for coverage, and high feedback rejection. SSOUNDS systems feature advanced DSP and beam steering to optimize coverage and minimize reflections. Always include a feedback suppressor and use directional microphones. For outdoor areas, weather-rated speakers with 100V line distribution are recommended.

Consult an acoustic engineer for precise SPL and coverage predictions. SSOUNDS provides free system design support to ensure your mosque achieves clear, balanced sound without excessive volume.
