HIGH-SPEED TRAIN NOISE REDUCTION

Protecting the environment, including reducing noise and ground vibrations from railways, has a very high priority at the DB AG. Extensive noise source investigations enabled noise reductions of ICE 1, ICE 2, as well as the new German high-speed train ICE 3. Above 100 km/h most of the noise is generated by wheels and rails, and at higher speeds than 300 km/h by aerodynamic sources. This overview discusses the most recent developments of identification and means of controlling noise from high-speed lines. For the covering abstract see ITRD E107776.
