Rail Dampers, Acoustic Rail Grinding, Low Height Noise Barriers

Rail dampers: There is a large variability in the results ranging from small increases in noise to a maximum noise reduction of usually not more than 3 dB. The effects of dampers are influenced by many parameters such as construction (rail pad stiff-ness) or traffic. However for many of the results these parameters were not measured.

Effect of Rail Grinding on Rail Vibration & Groundborne Noise: Results ...

An increase in rail roughness resulting from corrugation was considered a possible cause of increased groundborne noise levels. As a result, rail grinding was conducted during October 2003. This paper presents results of detailed measurements conducted during this process, highlighting the effect of rail condition on groundborne noise levels.
