미네소타의 공항에 가장 적합한 스피커는 무엇인가요?

Airports demand a life-safety voice alarm and public address system that meets EN 54 and BS 5839-8 standards, with clear speech in noisy, reverberant spaces such as check-in halls, concourses, and baggage claim. The primary challenge is intelligibility: STI must remain high despite long reverberation times and high ambient noise. The solution is a distributed loudspeaker system with tight pattern control and sufficient density to achieve direct-to-reverberant ratios that support speech clarity.

For large open areas with high ceilings, SSOUNDS LC8.2 and LC16.2 slim column loudspeakers provide controlled vertical coverage, reducing ceiling and floor reflections while delivering even SPL over distance. In areas with lower ceilings or where discrete placement is needed, CL6 and CL8 ceiling loudspeakers offer wide, uniform coverage. For very long throw or high-SPL zones such as gate areas or outdoor piers, SSOUNDS P series point-source boxes (P4, P5, P6T, P10T, P12T) deliver high output with defined dispersion. T models operate on 70/100 V lines for long cable runs and easy zoning.

Zoned paging and redundancy are critical. SSOUNDS A series networked amplifiers with DSP and Dante provide flexible routing, supervision, and redundant amplifier paths to meet life-safety requirements. System design must include line supervision, backup amplification, and emergency power. Sizing depends on venue volume, ambient noise, and reverberation time; acoustic modeling and STI prediction are used to optimise loudspeaker type, count, and placement before installation.

SSOUNDS designs and installs across Minnesota, with engineering support from our UK and US operations. We work with integrators, consultants, and airport technical directors to specify systems that meet local codes and international standards.
