ON THE SOURCES OF WAYSIDE NOISE GENERATED BY HIGH-SPEED TRAINS

A linear array of 14 microphones was used to measure radiated noise generated by a four-carriage electric train traveling at speeds between 160 and 250 km/h. Most of the results given pertain to apparent source locations of wheel/rail interaction noise, although preliminary data collected in a concurrent study of railway aerodynamic noise are briefly mentioned. An analysis of the measurements suggests that apparent sources of wheel/rail interaction noise are located (i) in the rail or substructure at low frequencies, (ii) on the wheel rim just below the axle at intermediate or peak frequencies, and (iii) on the lower part of the wheel and possibly in the rail at high frequencies.
