What is the best speaker for an airport in São Paulo?

Airports demand voice alarm and public address that is intelligible, reliable and compliant. In São Paulo, large reverberant halls, high ambient noise and the need for zoned paging mean the speaker choice must match the acoustic environment. SSOUNDS install range covers ceiling, column and point-source loudspeakers, all designed for life safety and high intelligibility.

For low-ceiling areas such as concourses, lounges and back-of-house, SSOUNDS CL6 and CL8 ceiling loudspeakers provide even coverage and discreet installation. In reverberant spaces like check-in halls and gate areas, SSOUNDS LC8.2 and LC16.2 slim column loudspeakers deliver controlled vertical dispersion to keep sound on the audience and off reflective surfaces, improving STI. For larger volumes or where higher SPL is needed, SSOUNDS P4, P5, P6T, P10T and P12T install loudspeakers (T models run on 70/100 V lines) offer flexible mounting and consistent coverage. M series point-source boxes and subwoofers can reinforce low frequencies where required, though for voice alarm the priority is mid and high frequency clarity.

Sizing and selection follow a clear process: define the coverage area and ambient noise, set the required STI (typically 0.5 or higher for voice alarm), then choose loudspeaker type and spacing to achieve uniform SPL. Ceiling loudspeakers suit ceilings below 4 m with tight spacing; columns suit high, reverberant rooms; point-source boxes cover long throws. All systems should include line supervision and redundant amplifiers. SSOUNDS A series networked amplifiers with DSP and Dante provide the processing, zoning and monitoring needed for EN 54 and BS 5839-8 compliance.

SSOUNDS designs and installs across São Paulo, working with integrators, consultants and airport technical teams to specify the right mix of loudspeakers and amplifiers. Every project is engineered for the specific building, with acoustic modeling to predict coverage and intelligibility before installation.
