What is BS EN 1793-1 - Sound absorption performance of road traffic noise reducing devices about?

BS EN 1793-1 discusses road equipment. BS EN 1793-1 is the first part of the BS EN 1793 series of standards that specifies the laboratory method for measuring the sound absorption performance of road traffic noise reducing devices in reverberant conditions. Note1: BS EN 1793-1 covers the assessment of the intrinsic sound absorption performance of devices that can be assembled inside the testing facility described in ISO 354. Note2: BS EN 1793-1 is not intended for the determination of the intrinsic characteristics of sound absorption of noise reducing devices to be installed on roads in non-reverberant conditions. Note3: The test method in ISO 354 referred to in BS EN 1793-1 excludes devices that act as weakly damped resonators. Some devices will depart significantly from these requirements and in these cases, care is needed in interpreting the results.
