22/30443386 DC
This standard 22/30443386 DC BS EN 16272-3-2. Railway applications. Infrastructure. Noise barriers and related devices acting on airborne sound propagation. Test method for determining the acoustic performance is classified in these ICS categories:
93.100 Construction of railways
This European Standard specifies a normalized railway noise spectrum for the evaluation and assessment of the acoustic performance of devices designed to reduce airborne railway noise near railways. All noise reducing devices different from noise barriers and related devices acting on airborne sound propagation, e.g. devices for attenuation of ground borne vibration and on-board devices, are out of the scope of this European Standard.
