What is the best speaker for an airport in Dakar?

Airports demand a life safety and public address system that delivers clear speech in challenging acoustic environments. In large halls with glass, stone and metal surfaces, reverberation can destroy intelligibility. The system must achieve a Speech Transmission Index (STI) that meets or exceeds the requirements of EN 54 and BS 5839-8 for voice alarm. Zoned paging, line supervision and redundant amplification are also essential. SSOUNDS designs and installs complete airport sound systems across Dakar, using our install range of loudspeakers and networked amplifiers.

For most airport spaces, the selection depends on ceiling height and room volume. In concourses, check-in areas, offices and corridors with standard ceilings, SSOUNDS CL6 and CL8 ceiling loudspeakers provide even coverage and discreet installation. In large reverberant halls such as baggage claim or departure lounges, where ceiling height is greater and speech clarity is critical, SSOUNDS LC8.2 and LC16.2 slim column loudspeakers offer controlled vertical dispersion to direct sound at listeners and reduce unwanted reflections. For very high ceilings, atriums or outdoor covered areas, SSOUNDS P4, P5, P6T, P10T and P12T install loudspeakers deliver higher SPL and longer throw. The T models operate on 70 V or 100 V lines for constant voltage distribution, which simplifies long cable runs and allows many loudspeakers on one amplifier channel.

Sizing and selection follow a few practical steps. First, define the coverage area and required SPL for each zone, typically 10 to 15 dB above ambient noise for paging, with higher levels for voice alarm. Second, calculate the number of loudspeakers needed based on ceiling height, dispersion angle and desired uniformity. Third, choose the appropriate model: ceiling loudspeakers for low ceilings, columns for reverberant halls, and point-source boxes for high or long-throw applications. Fourth, specify SSOUNDS A series networked amplifiers with DSP and Dante to provide zoning, equalisation, delay and redundancy. These amplifiers support line supervision and can be configured for failover, meeting the requirements of EN 54 and BS 5839-8 when integrated with a compliant voice alarm system.

SSOUNDS engineers use AI-assisted acoustic modelling and coverage prediction to optimise every system before it ships. This ensures that the specified loudspeakers and amplifiers will achieve the required intelligibility and coverage in the actual airport environment. We work with system integrators, consultants and venue technical directors to design and install systems that are reliable, intelligible and fully compliant. For an airport in Dakar, SSOUNDS provides design and installation support from our offices in the United Kingdom, the United States, Nigeria, Ghana and West Africa.
