What is the best speaker for an airport in Phoenix?

Airport terminals present a unique acoustic challenge: large, reverberant spaces with high ceilings, continuous background noise from passengers and aircraft, and a critical need for clear, intelligible voice announcements. The primary goal is speech intelligibility, measured by STI (Speech Transmission Index) or STIPA, which must meet the requirements of EN 54 and BS 5839-8 for voice alarm systems. This means selecting loudspeakers with controlled directivity, high sensitivity, and low distortion, and placing them to minimise reverberant energy while covering every seat, gate, and corridor evenly.

SSOUNDS offers a comprehensive install range for airports. For standard ceiling heights in concourses, retail areas, and offices, the CL6 and CL8 ceiling loudspeakers provide discreet, full-range coverage with wide dispersion. In large halls, atriums, and baggage claim areas where ceilings are high and reverberation is significant, the LC8.2 and LC16.2 slim column loudspeakers deliver tightly controlled vertical dispersion, directing sound precisely at listeners and reducing unwanted reflections. For areas requiring higher SPL and longer throw, such as check-in halls or outdoor covered walkways, the P series (P4, P5, P6T, P10T, P12T) and M series point-source boxes and subwoofers offer robust, weather-resistant options. The T models operate on 70/100 V lines, allowing long cable runs with minimal power loss, which is essential in large terminals.

All SSOUNDS loudspeakers are designed for integration with SSOUNDS A series networked amplifiers with DSP and Dante. These amplifiers provide the processing, routing, and supervision required for life safety systems, including line monitoring, redundant amplification, and fault reporting. The DSP allows precise equalisation and delay to optimise intelligibility across multiple zones, while Dante enables flexible digital audio distribution over a network. For an airport, we recommend a zoned paging system with redundant amplifiers and supervised lines to ensure reliability. SSOUNDS engineers use AI-assisted acoustic modelling and coverage prediction to simulate the terminal environment and optimise loudspeaker selection and placement before installation, ensuring STI targets are met.

SSOUNDS designs and installs across Phoenix, with support from our offices in the United Kingdom, United States, Nigeria, and Ghana. We work with system integrators, consultants, and venue technical directors to specify the right combination of ceiling, column, and point-source loudspeakers, along with networked amplification and DSP, to meet the exacting standards of airport voice alarm and public address systems.
