Best intelligibility at the platform

Holoplot and Deutsche Bahn put pilot into operation in Frankfurt

Holoplot and Deutsche Bahn commissioned the pilot installation of the new PA system at Frankfurt Central Station under the theme “Best intelligibility at the platform”. From 23 January, the test installation will improve the speech intelligibility of the announcements for six months at S-Bahn platforms 103 and 104. The installation consists of 23 audio modules installed at 11 positions.

The new public address system at Frankfurt Central Station puts previous technologies in the shadows. With the audio system from Holoplot, which is based on the principle of wave field synthesis, not only the sound dispersion on both the horizontal and vertical planes can be precisely defined, but also the shape of the wave front. This controlled sound propagation allows different areas of the station to be targeted differently with sound; in addition, this degree of precision also reduces reflections and thus increases the speech intelligibility of announcements significantly.

Holoplot is actively involved in the partnership with Deutsche Bahn and the Rhein-Main-Verkehrsverbund (RMV) to improve the customer experience at the railway station. “Holoplot is a prime example of how digital technologies can improve customer service at railway stations,” explains Susanne Kosinsky, responsible at Deutsche Bahn for the stations in Hesse, Rhineland-Palatinate and Saarland. The system will be extensively tested over the next six months. In addition, customer surveys will be carried out to determine the perceptions of travelers.

“Our technology offers the effect that the negative aspects of the room, e.g. the disturbing reflections, can be avoided to a large extent and the original signal can be transmitted as pure as possible. This means that the content can be played back with high quality where it is relevant,” describes Roman Sick, CEO of Holoplot, the advantages of the system.
