Charles de Gaulle Airport, Paris

All announcements perfectly intelligible

Charles de Gaulle Airport in Paris is France’s largest airport and one of the world's best known. Also known by its alternative name “Roissy”, the airport accommodates around 61 million passengers a year, making it Europe’s second busiest airport after London Heathrow. In order for announcements to be heard clearly by such large passenger numbers, Fohhn Focus systems have been installed in the rebuilt and extended Terminal 2E.

The terminal’s difficult acoustics have resulted in the choice of line array systems with Fohhn Beam Steering technology. These systems enable loudspeaker beams to be electronically controlled in real time via laptop, providing extremely precise sound coverage of the required area. This also ensures that the rest of the terminal space is not acoustically activated, thus minimizing reflections.

Three LFI-220 systems have been used to cover a 120 × 35 metre area with an 18 metre ceiling height. Two of the systems employ the Fohnn Two Beam Technology, where two separate beams can be generated from each loudspeaker. In this situation the two beams are used to provide simultaneous nearfield and distance coverage. The Fohhn Side Lobe Free technology also makes sure that any unwanted side lobes are suppressed. This degree of precision ensures that the systems can achieve the best possible sound results including excellent levels of speech intelligibility.

We congratulate Rock Audio Distribution on this successful project.
