This paper highlights the 2015 state of the two parallel packages of European standards on noise barriers and related devices acting on airborne sound propagation: one for roads, the other for railways. The first package has been developed by CEN/TC226/WG6. As in the road sector noise barriers are under the CPR 305/2011, the package includes a harmonized standard (EN 14388) and a set of supporting standards for testing or calculating the relevant characteristics: sound absorption, sound insulation, effectiveness of added devices on the top edge, mechanical and safety characteristics etc. Recently, a new specific standard about fire reaction has been added; moreover, a brand new standard on the sustainability of noise reducing devices is being drafted. The second package is being developed by CEN/TC256/SC1/WG40. In the railway sector, noise barriers are considered outside CPR 305/2011 but conforming to the Technical specifications for Interoperability (TSI). While the main characteristic of noise reducing devices remains the same, WG40 adapted to railways and improved the existing standards for roads. Moreover, some specific standards have been drafted and are on the way to publication: one presenting a calculation method for the mechanical performance under dynamic loadings caused by passing trains and the other on the resistance to fatigue due to the same loadings. Some standards on the evaluation of long-term performance of noise reducing devices are also present.
