DESCRIPTION

22/30452459 DC


This standard 22/30452459 DC BS EN 17936. Railway applications. Acoustics. Measurement of source terms for environmental noise calculations is classified in these ICS categories:
  • 17.140.30 Noise emitted by means of transport
  • 93.100 Construction of railways
The standard addresses the measurement of source terms for environmental noise calculation for rail traffic (including light rail). It is applicable to the measurement of in-service trains on operational tracks. It is not applicable to type acceptance testing of rolling-stock or tracks. The following rail traffic noise sources are in the scope: - Rolling noise ; - Traction noise ; - Aerodynamic noise ; - Impact noise (e.g. rail joints, switch & crossings, wheel flats) ; - Bridge noise ; - Squeal noise. Noise from rail vehicles at standstill is included e.g.: engine idling and auxiliary equipment. Noise from fixed installations (e.g.: stations, depots, electricity sub-stations) are not in the scope of this standard. Each source shall individually be characterized in terms of its frequency spectrum (up to one-third octave band details), source height and directivity. Rolling noise will then be described in terms of its generating wheel and rail roughness along with the vehicle and track transfer functions. Source terms will be specific to a vehicle and track type. The scope includes measurement procedures and conditions and sampling requirements.
