NOISE CONTROL OF STEEL RAILWAY BRIDGES IN SHINKANSEN

The noise caused by Shinkansen, the new trunk line system of Japanese National Railways where trains are operated at a speed of 210 km per hour, has become a serious problem for the people living along and near the lines. The problem is especially acute where the trains run on nonballast open floor type steel bridges. Japanese National Railways has investigated the characteristics of the noise. Considerably effective methods were developed, which reduce the noise level under or near the bridges by no less than 25 dBA, that is, from about 105 dBA to about 80 dBA.
