NOISE ABATEMENT ON BRIDGES. NOISE MEASUREMENTS ON THE ROSENHEIM BRIDGE

The influence of two variants of direct rail laying, on a steel bridge with orthotropic decking, on the excitation of the structure-borne noise of the bridge and the airborne sound radiation are analysed. In the case of a continuous rail laying on the decking plate, the level of the airborne noise radiated by the bridge increases by about 7 dB(A), whilst it remains unchanged on an average in the case of the laying of rails on so-called "elastic" sleepers. This negative finding implies a continuation of the theoretical practical investigations for developing a ballast-free track-laying system for steel bridges which, from the acoustic aspect, can replace the wooden-sleepered track on ballast bed with its high overall construction depth requirements.
