Deutsche Bahn is the largest railway operator and infrastructure owner in Europe with nearly two billion passengers every year. Frankfurt Central Station exists as one of Germany’s largest transportation hubs. For the hub, communication is key but with large space, many reflecting surfaces, various noise sources and a vast amount of information that must be communicated, this environment is difficult to master acoustically.
Given the demanding acoustic environments of this Deutsche Bahn train station, Holoplot’s task was to improve the existing situation. The goal was to reach a satisfactory level of speech intelligibility of at least >0.5 STI (Speech Transmission Index).
“Holoplot was able to demonstrate a significant and previously unattained improvement in acoustics at the live test in Frankfurt and thus represents a very exciting technology for Deutsche Bahn.”
