Webnoise at source [11]. Rail dampers are particularly effective when tracks are fitted with soft pads (low strain stiffness below 250 MN/m). Various forms of rail damper have been designed to increase the track decay rate without the need for higher pad stiffness [12-15]. Usually, such dampers are bolted or clipped onto the rail between the sleepers. WebCORE – Aggregating the world’s open access research papers
