Road traffic noise reducing devices - Test method for determining the acoustic performance - Part 6: Intrinsic characteristics - In situ values of airborne sound insulation under direct sound field conditions

Le présent document spécifie une méthode d''essai permettant d''évaluer la performance d''isolation aux bruits aériens des dispositifs de réduction du bruit conçus pour les routes dans des conditions de champ acoustique direct (non réverbérantes). Cette méthode peut être appliqué sur site, c''est-à-dire sur le lieu d''installation des dispositifs de réduction du bruit. Elle est appliquée de manière non destructive, sans endommager la surface du dispositif de réduction du bruit.
