EUROLAB, with its state-of-the-art accredited laboratories and expert team, offers precise and rapid testing services within the scope of EN 16272-1 test. This European Standard specifies a laboratory method for measuring the sound absorption of flat noise barriers or flat coverings used in retaining walls or tunnels.
It covers the evaluation of the intrinsic sound absorption performance of noise barriers and related devices affecting airborne sound propagation designed for railways, which can be reasonably installed within the test facility described in EN ISO 354. The test method in EN ISO 354, This European Standard is strictly valid for flat absorbers only and specifically excludes devices acting as slightly damped resonators. Some devices may deviate significantly from these requirements, and in these cases caution is warranted in interpreting the results.
All noise-reducing devices other than noise barriers and related devices affecting airborne sound propagation, e.g. devices for reducing ground-borne vibration and devices on board, are outside the scope of this European Standard.
It is not concerned with the on-site determination of sound absorption performance or the acoustic efficiency (insertion loss) at receiver locations, which also depends on factors unrelated to the product itself; dimensions of the barrier and the quality of the installation work and site geometry, ground impedance, meteorological effects, etc. Field factors such as. The test is designed to allow the intrinsic sound absorption performance of the device under test to be measured and the resulting rating to be made. assists in the selection of devices for specific railway applications.
The test method described in this European Standard should not be used to fully determine the specific characteristics of sound absorption for noise-reducing devices to be installed in non-reverberant conditions.
This method can be used to qualify noise reduction devices for other applications; It will be installed along roads or in nearby industrial areas. In such cases, single-digit ratings should be calculated using an appropriate spectrum.
