Introduction
This document presents a measurement method to collect information about the noise insulation of rail
bound vehicle gangway systems. These components need their own measurement procedure as the
geometrical sound distribution situation is not in line with the basic assumptions of general standards
about noise insulation measurements as provided for building elements, etc.
In this document, a number of different setups are described, which represent possible approaches to
the ideal test situation. As the approaches can contradict the ideal sound fields, the document includes
methods to assess the influence of reflections and other difficulties in order to reduce the uncertainties
of these test methods to an acceptable amount in Annex A.
1 Scope
This document specifies a measurement method and conditions to obtain reproducible and comparable
sound reduction indices of all kinds of rail bound vehicles’ gangway systems as specified in EN 16286-1.
The setup includes all components of the system mounted like this is done between two adjacent car
bodies within the train, so that a person will be able to use the gangway system, consisting of e.g.:
— the bridge system (footplate);
— side panels;
— flexible components (bellows);
— mounting systems;
— elements to couple parts in the case of separable gangway systems.
The method is applicable to type testing of gangways.
This method is not applicable to:
— interior noise measurements in vehicles;
— structure borne noise measurements.
The type testing procedures specified in this document are of engineering grade (grade 2) in the
frequency range from 100 Hz up to 5 000 Hz.
NOTE This is the preferred range for noise declaration purposes, as specified in EN ISO 12001. If test
conditions are relaxed, the results are no longer of engineering grade (grade 2).
