NOISE LEVELS ASSOCIATED WITH METROPOLITAN RAILWAYS OR URBAN RAPID TRANSPORT SYSTEMS. VDI-SPECIFICATION 2716

GERAEUSCHSITUATIONEN BEI STADTBAHNEN. VID-RICHTLINIE 2716

The purpose of the specification is to provide a basis for determining the noise levels under various local operating conditions and track alignments, for use in the planning of metropolitan railway systems. The terms are first defined: metropolitan railway sound level: maximum and minimum sound levels. Both the maximum sound level for the passage of a train at a distance of 7.5 M from the track centre line under normal conditions and also the influences on the maximum level of variations in the measurements specified in the specification are described to illustrate the problems of external noise from metropolitan railway vehicles (or rapid transit vehicles) on elevated stretches. The influences covered include: speed; acceleration and braking noises; elevated construction, wheel, tires or rims; wheel construction; rails; layout of stretch; the relationship of the direction of the noise waves to the vertical plane; building development at the side of the track; acoustic screens and curves in the track. The problem of internal noise is also treated and the influences on the internal noise level caused by deviations from the specified measurement conditions of several parameters are covered: speed; tunnels; elevated construction; coach occupancy; wheel, tire or rims; construction of wheels and rails. Other factors covered are the problems of noise at underground stations, both for incoming and departing trains, the noise from moving trains in tunnels, in sections directly underneath the tracks as well as in houses near stretches of tunnel. Finally, in an appendix, mathematical formulae are developed for the calculation of maximum and median noise levels.
