Optionally co-design standards:
This standard specifies the laboratory method for measuring the sound absorption of flat noise barriers or flat cladding for retaining walls or tunnels. It covers the assessment of the intrinsic
sound absorption performance of roadside noise reducing devices which can reasonably be assembled inside the testing facility described in EN 20354. The test method in EN 20354, referred to in this standard, is strictly valid only for plane absorbers and in particular excludes devices which act as weakly damped resonators. Some devices will depart significantly from these requirements and in these cases care is needed in interpreting the results.
