| Note in Official Journal: | |
| Subject of the standard: | This document describes a test method for measuring a quantity representative of the intrinsic characteristics of sound absorption from railway noise barriers and related devices acting on airborne sound propagation, the sound reflection index RI, and then calculate a single-number rating for sound absorption from it. The test method is intended for the following applications: - determination of the intrinsic characteristics of sound absorption of noise barriers and related devices acting on airborne sound propagation to be installed along railways, to be measured either on typical installations alongside railways or on a relevant sample section; - determination of the intrinsic characteristics of sound absorption of noise barriers and related devices acting on airborne sound propagation in actual use under direct sound field conditions; - comparison of design specifications with actual performance data after the completion of the construction work; |
