요하네스버그 공항에 가장 적합한 스피커는 무엇인가요?

Airports demand intelligible voice alarm and public address that meets EN 54 and BS 5839-8 standards, with zoned paging, line supervision and redundant amplification. The best speaker is not one model but a system matched to each acoustic zone. In large reverberant halls, such as check-in and baggage reclaim, column loudspeakers like the SSOUNDS LC8.2 and LC16.2 provide controlled vertical coverage to keep sound off reflective ceilings and floors, raising STI. In concourses, lounges and back-of-house areas, SSOUNDS CL6 and CL8 ceiling loudspeakers deliver even coverage with low visual impact. For high-SPL areas like gate hold rooms and external forecourts, SSOUNDS P4, P5, P6T, P10T and P12T install loudspeakers (T models on 70/100 V lines) offer the required output and weather resistance. M series point-source boxes and subwoofers handle larger spaces or special effects where needed.

Selection and sizing start with the acoustic model. SSOUNDS engineers use AI-assisted prediction to map STI across the terminal, then choose loudspeaker types, quantities and positions to meet the required coverage and intelligibility. Ceiling loudspeakers are spaced for overlapping coverage at ear height, typically 3 to 6 metres apart depending on ceiling height and ambient noise. Column loudspeakers are mounted at 2.5 to 4 metres, aimed to cover the listener plane without excessive rear spill. For 70/100 V line systems, tap settings are chosen to balance SPL and amplifier load, with supervision to detect line faults. Redundant A series amplifiers with DSP and Dante provide zoned paging, failover and networked audio distribution.

SSOUNDS designs and installs across Johannesburg, with support from our African HQ in Abuja, Nigeria, and our UK and US operations. We work with system integrators, consultants and airport technical directors to deliver compliant, intelligible and reliable sound systems.
