Sound Reduction of the high-speed railroad noise by the deck plate of the Bridge

Railroad noise is one of the main causes of environmental impact. Whenever a new railroad line is planned or a housing project near an existing railroad is proposed, an estimate of the relevant noise levels is usually required. For this, it is necessary to quantify those parameters that affect the railroad noise. This paper deals with an estimation of railroad noise by the barrier and deck plate of the bridge.
