Abstract

In the framework of the economic stimulus plan “Konjunkturprogramm II” of the German government new measures for noise and vibration mitigation have been tested. The analyses of the measurements on 82 measurement sites shows as result, that in the case of rail dampers, a noise mitigation of about 2 dB(A) dependent on the type of train is possible. The effect of rail shields showed a little bit better results of about 3 dB(A) in summary. The effect of low noise barriers was modeled with regard to the German calculation method with the position of the noise source of rolling noise on the top of the rail. In this case, the shielding - effect of the low noise barrier is reduced comparable with a reduction of the height of the barrier of 30 %.
