The purpose of this research project is first to collect the literature on the anti-noise measures taken by railroad operators around the world. German. Denmark, Switzerland, US and Japan are among the countries that have been surveyed. The anti-noise measures used by these country are concentrated on traction noise and wheel and rail interaction noise. The counter measures taken by the operator in Taiwan are concentrated on the speed control, construction of sound barrier and the improvement of rail condition. Secondly, the understand the effectiveness of anti-noise measures, 20 locations along the TaiRail system where the noise complaint has been filed and Anti-noise measure was carried out were selected for test the effectiveness of these anti-noise measures. ISO standard 3095 and 10847 were used to measure the railway noise and the insertion loss of the noise barrier. Also24 hours noise level monitoring were carried out at these locations to determine if the noise from the rail system complies to the noise limit set by Taiwan EPA. Finally, the effectiveness of these counter measures were compiled together with theSOP for carrying out these counter measured. The counter measures include abatement for noise source, transmission path and for the receivers. And a procedure for carrying out noise abatement project were also proposed in the project.
