Abstract:

Performance of inclined noise barriers in railway noise mitigation is studied in this paper. At the first part, mitigation performance of a partial sound barrier is experimentally examined. Validityof the Kurze & Anderson formula is investigated in presence of a moving sound source such as alocomotive. A numerical model is then provided in SOUNDPLAN software and it is validated by the supporting experimental results. For different frequencies 500, 1K, 1.5K and 2 KHzoptimal inclination angle is obtained for various geometrical configurations. Sound spectrum is then obtained for different types of locomotives in a series of filed measurement tests. Using thereal sound data for different types of passenger and freight trains, optimal barrier configurationsare obtained. It is shown that the inclination angle can play a significant role in noise mitigation level remarkably in high height regions.
