Deutsche Bahn „Infopunkt Lärmschutz“The Deutsche Bundesbahn (DB; German Rail) works on the projects ‘Focus on Noise Protection’ and ‘Infomobile Noise Protection’. In support of these DB projects, the HHI team made180° HD panoramic video recordings from moving trains of various makes (ICE, freight trains). Also the nature and level of the accompanying sounds were recorded realistically using 3-D multi-channel audio recording systems.
In these noise protection projects, the TiME Lab serves as acoustic reference location. By means of 180° HD panorama projections based on wave field synthesis, the HHI recording team was able to demonstrate the true effects of noise protection measures to larger groups.
It is the joint objective of the German Government and the German Railroad Administration to cut the noise from passing freight trains in halve until 2020. The joint project with the HHI provides data for noise protection plans.
