인디애나의 공항에 가장 적합한 스피커는 무엇인가요?

Airport terminals demand a life safety and public address system that delivers clear speech in large, reverberant spaces such as check-in halls, departure lounges and baggage claim. The system must meet EN 54 and BS 5839-8 standards for voice alarm, with line supervision, redundant amplifiers and zoned paging. Intelligibility is measured by STI, and achieving high STI requires careful selection of loudspeaker type, placement and processing.

For ceiling heights up to 4 metres, SSOUNDS CL6 and CL8 ceiling loudspeakers provide even coverage and are ideal for offices, corridors and smaller rooms. In areas with higher ceilings or where ceiling mounting is impractical, LC8.2 and LC16.2 slim column loudspeakers offer controlled vertical dispersion to direct sound at listeners and reduce reverberant energy. For large open spaces like departure lounges, P series install loudspeakers (P4, P5, P6T, P10T, P12T) deliver high SPL and pattern control. The T models operate on 70/100 V lines for long cable runs and multiple speakers per zone. M series point-source boxes and subwoofers can reinforce low frequencies for background music or paging chimes, but speech clarity remains the priority.

Zoning is critical: separate zones for check-in, security, gates, baggage claim and outside areas allow targeted messaging. SSOUNDS A series networked amplifiers with DSP and Dante provide flexible routing, equalisation and delay to optimise intelligibility. Redundant amplifiers ensure continued operation if one fails. All loudspeakers and lines are supervised to detect faults, meeting EN 54 requirements. SSOUNDS engineers use AI-assisted acoustic modelling to predict coverage and STI before installation, ensuring the design meets the project's performance criteria.
