Method of damping railroad noise and railroad noise damping members

摘要

A method for reducing noises produced from a railroad when trains travel on rails. A vibration/noise damping member made of lead is fixed to the vertical rib portion of a rail, one side of a wheel, a joint bar for rails, or one side of a railroad overpass or iron bridge. The damper may have a plate shape or any other sectional shape. The vibration/noise damper effectively absorb and damp vibration energy and noises produced when trains travel on rails.
