    Abstract - (Show below) - (Hide below)

    Defines the laboratory method for measuring the sound absorption performance of road traffic noise reducing devices in reverberant conditions. Also covers the assessment of the intrinsic sound absorption performance of devices that can reasonably be assembled inside the testing facility described in EN ISO 354.
