Seville Airport launches LDA Audio Tech voice evacuation and public address system

The Spanish company has deployed in this airport installation a complete system, with equipment certified according to international EN standards 54.

Work of the architect Rafael Moneo and inspired by the traditional Andalusian culture and architecture, The Seville Airport receives each year more than 6 millions of passengers, Performed 58.000 operations and sum 12.500 tons of cargo transported, which makes it one of the main airport facilities in Spain.

After renovating its facilities on several occasions (the most important was held on the occasion of the Seville Expo in 1992), the airport has had regular updates of its technological systems to offer the best service to its passengers and maximum security in the terminal.

One of the latest renovations has had the public address system and voice evacuation as the protagonist, that has been entrusted to equipment certified according to international standards EN 54 manufactured by LDA Audio Tech.

In order to know in depth the needs of the enclosure before the installation of this system, a previous acoustic study was prepared with measurements of the sound pressure level (Spl) and intelligibility (STI), as well as another subsequent study to verify the installation and make the necessary adjustments so that the electroacoustic system complies with the requirements established by these parameters.

Thanks to this, the main points to be improved and the areas of special interest for the installation have been precisely known., providing them with the ideal equipment to achieve the best response of the public address system in any type of acoustic situation.

This public address and voice evacuation system, EN certificate 54 and designed by LDA Audio Tech for Seville Airport, allows the use of up to 64 simultaneous audio channels and unlimited audio sources, in addition to its integration with remote evacuation panel, facilitating phased evacuation throughout the enclosure.

The installed equipment is complemented by a commissioning service, configuration and training of the specialized AENA personnel who will be in charge of the operation of the system at the airport. LDA's engineering and support team has extensive experience in this type of complex environment for optimal operation of the installation.
