| Predmet normy: | This document specifies a test method for measuring a quantity representative of the intrinsic characteristics of sound reflection from road noise reducing devices, the sound reflection index, and then calculate a single-number rating for sound absorption from it. This document is applicable to: — the determination of the intrinsic characteristics of sound absorption of noise reducing devices to be installed along roads, to be measured either on typical installations alongside roads or on a relevant test specimen section; — the determination of the intrinsic characteristics of sound absorption of road traffic noise reducing devices in actual use under direct sound field conditions; — the comparison of design specifications with actual performance data after the completion of the construction work; — the verification of the long-term performance of road traffic noise reducing devices (with a repeated application of the method). This document does not apply to: — the determination of the intrinsic ... |
