Calm ambience

thanks to coherent design and optimum acoustics

Over a construction period of eleven years, a light tail tunnel was built under Karlsruhe city centre and seven stations were relocated underground.

The stations are an understated, uniform, and cohesive sequence of spaces. In addition, they provide a contrast to the visual and acoustic overload of the busy areas above ground

When constructing underground stations in Germany, the acoustic challenges primarily relate to the areas where the ticket barriers are and, in particular, the extensive waiting areas at platform level. Functioning acoustics are essential here both for public address calls during normal operation and in the event of possible evacuations.

Large-format and open-joint suspended ceilings with expanded granulate panels that can absorb high levels of humidity and thereby help prevent the potential growth of mould, plus mechanically applied acoustic flocking, ensure optimum acoustics.

Overall, the acoustic measures and the uniform design of the surfaces create a calm ambience that offsets the many stimuli and noise of the busy city.
