EN 16951-1:2018 (E) 5 Introduction Noise barriers and related devices acting on sound propagation alongside railways should not only fulfil their acoustic function and structural design requirements in accordance with appropriate documents, but also maintain their performance during the required working life. The acoustic elements need to resist the actions of agents within the line side environment that could significantly degrade their performance. The acoustic characteristics of noise barriers and related devices acting on sound propagation can deteriorate significantly over the duration of their working life if they are not installed or maintained in accordance with the manufacturer’s recommendations, or if the materials are not appropriate for the line side environment. All elements in the construction of noise barriers and related devices acting on sound propagation should be resistant to electrolytic or/and chemical corrosion and embrittlement, be dimensionally stable and have generally a high ageing resistance in many differing conditions. SIST EN 16951-1:2018
