‘Chopin Airport now has a state-of-the-art public address system’
Poland - Chopin Airport in Warsaw, named after the famous Polish composer Frédéric Chopin, has recently undergone an impressive improvement in acoustic technology. The installation of an extensive Praesensa system from Bosch Building Technologies marks a turning point in the way information and music is transmitted and played in the airport building.
The new system features advanced loudspeaker technology and a high level of automation, providing outstanding sound quality and clear, crisp voice transmission, which is of great benefit to the operator, passengers and ground staff.
The new passenger information system is based on the Praesensa solution from Bosch. It uses LS1-OC100E-1 hemi-directional ceiling loudspeakers and LC1-UM12E8 built-in loudspeakers, which ensure that passengers at every gate are addressed with pinpoint accuracy and excellent intelligibility.
By integrating a text-to-speech solution from a third-party provider, the flight number, airline, destination and boarding information are automatically retrieved from the central computer at Chopin Airport and reproduced in synthesized voice information. These are output in Polish and English as well as other available languages, achieving a previously unattainable sound quality. The result is a significant reduction in the workload of airport staff.
The modernisation of the public address and voice alerting system was urgently needed, as the old analogue system had reached its limits. Information was often lost in an indistinct fog of sound, and manual announcements of boarding information were both time-consuming and labour-intensive.
The integration of the new system into the airport's existing infrastructure went smoothly, which significantly shortened the installation time. The automation and increased efficiency provided by the Praesensa system are appreciated by both staff and passengers alike. The scalability of the system ensures its suitability for future developments and requirements.
“Chopin Airport now has a state-of-the-art public address system. The fact we could build on the existing IP infrastructure significantly reduced the amount of time for the installation work,” says Józef Bycul, project manager at Bosch Building Technologies.
