Railway applications - Infrastructure - Noise barriers and related devices acting on airborne sound propagation - Test method for determining the acoustic performance (series; anchored on Part 1 - sound absorption)

Scope

Multi-part CEN series of laboratory and in-situ test methods for the acoustic performance of railway noise barriers and related devices acting on airborne sound propagation. This entry anchors on Part 1, covering sound absorption under diffuse sound-field conditions; companion parts cover airborne sound insulation, normalised railway noise spectra and direct-field measurement. It is used by infrastructure managers and noise-barrier manufacturers for product qualification against noise-mitigation requirements.
