더블린 공항에 가장 적합한 스피커는 무엇인가요?

Airports demand more than background music. They require life safety voice alarm and public address to EN 54 and BS 5839-8 standards, with clear speech in large, reverberant spaces such as check-in halls, departure lounges and baggage reclaim. The primary engineering challenge is intelligibility: achieving high STI (Speech Transmission Index) despite long reverberation times, high ambient noise and complex geometry. Zoned paging, line supervision and redundant amplifiers are also essential for both routine operations and emergency evacuation.

SSOUNDS approaches airport sound from the system level. We use predictive acoustic modelling to map coverage and intelligibility before any hardware is specified. For terminal buildings, we typically combine SSOUNDS CL6 and CL8 ceiling loudspeakers for low ceilings and offices, LC8.2 and LC16.2 slim column loudspeakers for concourses and gate areas where controlled vertical dispersion is needed, and P4, P5, P6T, P10T and P12T install loudspeakers for larger spaces. The T models operate on 70/100 V lines, simplifying long cable runs and zone switching. For very large or high-reverberation areas, M series point-source boxes and subwoofers provide higher SPL and pattern control. All loudspeakers are driven by SSOUNDS A series networked amplifiers with onboard DSP and Dante, enabling redundant amplifier paths, line monitoring and zone management.

Selection and sizing depend on room volume, reverberation time, ambient noise and required STI. As a rule, use ceiling loudspeakers in areas with ceiling heights below 4 metres, columns in spaces up to 8 metres where walls are reflective, and point-source or line array systems in large atria or long concourses. The number of loudspeakers is determined by coverage angle, SPL target and the need for overlapping coverage to maintain intelligibility. SSOUNDS engineers use AI-assisted acoustic modelling to optimise these parameters, ensuring every zone meets the required STI and SPL without excessive box count.

SSOUNDS designs and installs across Dublin. Our team works with consultants, integrators and airport technical directors to deliver compliant, intelligible and reliable sound systems. We ship and support internationally from our bases in the United Kingdom, United States, Nigeria and Ghana, and we invite you to contact us to discuss your project.
