Description

This document specifies a method for the determination of characteristics of rail traffic noise in the near field on open track in order to determine the development of traffic noise emissions in an automated and unobserved manner (usually longer than four weeks). These measurement data are collected at a specified location near the track . The method has three different quality levels for the acquisition and characterisation of sound events caused by railway traffic. The quality levels differ in the effort involved and in their significance. The user selects the quality level suitable to the respective task at hand. In all quality levels, measuring equipment is used that can record the sound pressure level and other parameters for each sound event. The measurement data are stored on site and/or transmitted to a central data collection point. Using a standardized evaluation method, characteristic values are determined from the measurement data. In this way, both the measured individual sound events at the various measuring stations and their development over time are documented and presented in a uniform and comprehensible manner according to defined criteria.
