Introduction
Road Traffic Noise Reducing Devices alongside roads are not only required to fulfil their acoustic function and
structural design requirements in accordance with appropriate European 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 roadside environment that could significantly
degrade their performance.
The acoustic characteristics of a Road Traffic Noise Reducing Device can deteriorate significantly over the duration
of its working life if it is not installed or maintained in accordance with the manufacturer’s recommendations, or if
the materials are not appropriate for the roadside environment.
Until now no methods exist that could be used for the evaluation of the durability of acoustic characteristics of noise
reducing devices. Therefore new methods were introduced in CEN/TS 1793-5, which are designated in this
standard. The use of these methods may produce values for the sound reflection DL of noise reducing devices
RI
that are different from the values of sound absorption DL resulting from EN 1793-1, which are the basis for the
α
product characterisation of absorptive noise reducing devices. These differences should be dis
