Prediction of Community Noise from Rail Systems

Source

This paper presents a simple procedure for predicting noise in the vicinity of rail lines including intercity freight and passenger services and metropolitan systems. The procedure accounts for the effects of speed; wheel and rail condition; travel on bridges and elevated transit structures; geometrical spreading of sound energy; excess attenuation due to propagation over the ground and through the air; and barrier attenuation by sound screens, cuttings, embankments, and houses. Aweighted sound pressure level is the basic quantity predicted; equations are given to determine various noise exposure measures such as the 24-hour energy equivalent sound level (Leq (24h)), the day-night average sound level (Ldn) and the community noise equivalent level (CNEL).
