Road traffic noise reducing devices. Procedures for assessing long term performance - Acoustical characteristicsBS EN 14389 1: 2007 defines the means for evaluating the acoustic durability of Road Traffic Noise Reducing Devices. Road Traffic Noise Reducing Devices alongside roads are not only required to fulfil their acoustic function and structural design requirements in accordance with appropriate standards, but also to maintain their performance for a reasonably economic working life. The acoustic elements have to resist the actions of agents within the
