SOUND-PROOF STEEL RAIL BRIDGES

SCHALLGEDAEMPFTE STAHLBRUECKEN FUER SCHIENENVERKEHR

Elastic rail support can only be used under certain conditions because permissible rail movement is limited; limiting the elasticity also reduces the sound-proofing effect. By coating the large steel sheets of the bridge with sound-proofing materials and by use of cladding, good results can be obtained. Certain thickness conditions need to be respected. All these measures are only successful for certain frequency ranges (never below 200 Hz) and within given temperature limits. The non-bearing parts of the bridge can hardly be sound-proofed. Heavy concrete slabs, hanging and floating on steel girders are very effective but they increase the weight of steel that has to be supported.
