How loud should a mosque sound system be?
Quick answer
A mosque sound system should deliver clear, intelligible speech at 75–85 dB SPL at listener positions, with peaks up to 95 dB for calls to prayer, avoiding distortion and feedback.
The primary goal in a mosque is speech intelligibility, not extreme volume. Target a consistent 75–85 dB SPL across the congregation area for sermons and prayers, with headroom for the adhan (call to prayer) reaching up to 95 dB SPL. Excessive volume causes reverberation issues and listener fatigue, especially in acoustically live spaces common in mosques.
SSOUNDS recommends a distributed system using multiple point-source loudspeakers or a compact line array, positioned to cover seating evenly. For a typical mosque (e.g., 500–1000 m²), a pair of SSOUNDS high-output point-source cabinets per zone, paired with subwoofers for low-frequency warmth, provides clean coverage. Use DSP to limit maximum output and apply EQ to reduce feedback-prone frequencies.
Key factors: room acoustics (reverberation time), speaker placement (avoiding walls/columns), and microphone technique. A well-tuned system at moderate volume outperforms a loud, poorly placed one. SSOUNDS engineers can model coverage and set safe SPL limits to protect hearing and ensure clarity.
Key things to consider
- Target 75–85 dB SPL for speech, up to 95 dB for calls to prayer.
- Use distributed speakers (point-source or compact line arrays) for even coverage.
- Apply DSP to limit maximum SPL and reduce feedback.
- Consider room acoustics; avoid over-amplification in reverberant spaces.
- Choose weather-resistant models if outdoor areas are included.
