PREDICTION OF COMMUNITY NOISE FROM RAIL SYSTEMS

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. A-weighted 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, the day-night average sound level and the community noise equivalent level.
