23/30468473 DC
This standard 23/30468473 DC Draft BS EN 1793-2. Road traffic noise reducing devices. Test method for determining the acoustic performance is classified in these ICS categories:
93.080.30 Road equipment and installations
17.140.30 Noise emitted by means of transport
This document specifies the laboratory method for measuring the airborne sound insulation performance of road traffic noise reducing devices in reverberant conditions. It covers the assessment of the intrinsic performance of barriers that can reasonably be assembled inside the testing facility described in EN ISO 10140-2 and EN ISO 10140-4. This method is not intended for the determination of the intrinsic characteristics of airborne sound insulation of noise reducing devices to be installed on roads in non-reverberant conditions.
