Road traffic noise reducing devices - Test method for determining the acoustic performance - Part 1: Intrinsic characteristics of sound absorption under diffuse sound field conditions; German version EN 1793-1:2017

Overview
This European Standard specifies a test method for qualifying the sound absorption performance of noise reducing devices designed for roads (a measure of intrinsic performance). It is not concerned with determining insertion loss (extrinsic performance) which depends on additional factors which are not related to the product itself, such as the dimensions of the barrier and quality of installation work and site factors such as ground impedance, site geometry etcetera. The measurement results of this method for sound absorption are not directly comparable with the results of the in situ method (EN 1793-5), mainly because the present method uses a diffuse sound field, while the in situ method assumes a directional sound field. The committee responsible for this standard is NA 005-10-26 AA "Lärmschutzvorrichtungen (SpA zu CEN/TC 226/WG 6)" ("Noise reducing devices (national mirror committee for CEN/TC 226/WG 6)") at DIN.
