What is the best speaker for an airport in Portugal?

Airports demand a life safety and public address system that is intelligible, reliable and zoned. The primary challenge is speech intelligibility in large, reverberant spaces such as check-in halls, departure lounges and baggage reclaim. To meet EN 54 and BS 5839-8, the system must provide clear voice alarm messages, line supervision, redundant amplification and zoned paging. SSOUNDS engineers approach this by modelling the acoustic environment, selecting loudspeakers with controlled directivity and using DSP to optimise coverage and STI.

For ceiling heights up to around 4 metres, SSOUNDS CL6 and CL8 ceiling loudspeakers offer discreet, full-range reproduction with wide coverage. In spaces with high ceilings or significant reverberation, such as security halls or retail areas, SSOUNDS LC8.2 and LC16.2 slim column loudspeakers provide tight vertical directivity to keep sound on the audience and off reflective surfaces. For very large volumes or long-throw applications, SSOUNDS P4, P5, P6T, P10T and P12T install loudspeakers (T models for 70/100 V line) deliver higher SPL and controlled coverage. M series point-source boxes and subwoofers can reinforce low frequencies where needed, though speech remains the priority.

Sizing and selection follow a simple process: define the zones, calculate the required SPL and intelligibility (STI) for each space, then choose loudspeaker types and quantities to achieve even coverage. SSOUNDS A series networked amplifiers with DSP and Dante provide the processing, routing and supervision required for EN 54 compliance. Redundant amplifiers and line supervision ensure the system remains operational during an emergency. SSOUNDS designs and installs across Portugal, working with local partners to deliver projects that meet both regulatory and acoustic requirements.
