루사카의 공항에 가장 적합한 스피커는 무엇인가요?

Airports demand intelligible voice alarm and public address that meets EN 54 and BS 5839-8 standards, especially in large reverberant halls where speech must remain clear. SSOUNDS install range covers this: ceiling loudspeakers (CL6, CL8) for low ceilings and offices, slim column loudspeakers (LC8.2, LC16.2) for spaces with high ceilings and hard surfaces, and point-source boxes (P4, P5, P6T, P10T, P12T) or M series for high-SPL areas and outdoor zones. The T models operate on 70/100 V lines for long cable runs and easy zoning.

Selection starts with the acoustic environment. In check-in halls and baggage reclaim, where reverberation times are long, column loudspeakers like the LC8.2 or LC16.2 provide tight vertical coverage and reduce unwanted reflections, improving STI. For concourses and retail areas with lower ceilings, CL6 or CL8 ceiling loudspeakers offer even coverage and discreet installation. In large open spaces or piers with high ceilings, P series or M series point-source boxes deliver higher SPL and controlled dispersion. Outdoor areas such as aprons or car parks may need weather-resistant M series boxes.

Sizing and zoning are critical. Each zone should have its own amplifier channel or networked audio channel, with SSOUNDS A series networked amplifiers providing DSP and Dante for flexible routing and redundancy. Line supervision and redundant amplifiers ensure the system remains operational during emergencies. The number of loudspeakers per zone depends on ceiling height, target SPL, and intelligibility requirements; a common approach is to use ceiling loudspeakers at 2 to 4 times the ceiling height spacing for even coverage, while columns are placed to cover specific areas without overlap. SSOUNDS engineers use AI-assisted acoustic modeling to predict coverage and STI before installation.

SSOUNDS designs and installs across Lusaka, with support from our offices in the United Kingdom, United States, Nigeria, Ghana, and West Africa. We work with system integrators, consultants, and airport technical directors to specify the right mix of SSOUNDS loudspeakers and amplifiers, ensuring compliance and performance.
