Audience members report that the system sounds clear at the front but becomes uneven and unclear toward the rear seating, with noticeable level jumps when walking between sections."

Commissioning Focus

Coverage uniformity, tonal consistency, delay optimization, and gain structure stability.

After Commissioning
Coverage is balanced across all audience zones, tonal response is consistent, and delays are aligned so speech and program audio remain stable throughout the hall.

The imam’s voice is audible near the mihrab but becomes muffled or unstable in other prayer zones, with frequent feedback occurring whenever volume is increased for larger congregations.

Commissioning Focus

Speech intelligibility focus, feedback margin, zoning logic, and consistent voice projection.

After Commissioning
Speech remains clear and natural across all prayer zones, feedback is controlled, and voice projection is consistent without excessive volume.

Remote participants complain about echo and inconsistent voice levels, while in-room microphones intermittently trigger sudden volume changes or cut-offs during discussions.

Commissioning Focus

Microphone-to-loudspeaker integration, echo/AGC behaviour, DSP voice optimization, usability.

After Commissioning
Microphones, loudspeakers, and conferencing platforms function as a unified system, delivering consistent voice levels, natural speech, and reliable user operation.

Students seated at the sides or back struggle to understand the instructor, even though the lecturer hears themselves clearly on stage

Commissioning Focus

Speech reinforcement clarity, instructor mic reliability, audience coverage, and system headroom.

After Commissioning
Speech is intelligible across the entire room, instructors can move freely, and the system maintains clarity without pushing volume limits.

Announcements are loud but difficult to understand, with noticeable timing differences between speaker zones that cause echo and listener fatigue during events.

Commissioning Focus

Zoning strategy validation, high-SPL stability, protection settings, delay timing for large areas.

After Commissioning
Zoned systems are time-aligned, announcements are clear and controlled, and the system operates reliably even at higher sound levels.

Speech and announcements become inconsistent depending on weather and crowd noise, requiring operators to continuously adjust levels to maintain intelligibility without triggering system faults.

Commissioning Focus

Environmental constraints, wind/noise effects, coverage control, power and protection verification.

After Commissioning
Zoned systems are time-aligned, announcements are clear and controlled, and the system operates reliably even at higher sound levels.
