Road traffic noise reducing devices - Test method for determining the acoustic performance - Part 2: Intrinsic characteristics of airborne sound insulation under diffuse sound field conditions

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.

Lärmschutzvorrichtungen an Straßen - Prüfverfahren zur Bestimmung der akustischen Eigenschaften - Teil 2: Produktspezifische Merkmale der Luftschalldämmung in diffusen Schallfeldern

Diese Europäische Norm legt das Laborprüfverfahren zur Ermittlung der Luftschalldämm-Eigenschaften von Lärmschutzwänden an Straßen unter halligen Bedingungen fest. Sie ist bei der Bewertung der produktspezifischen Eigenschaften derjenigen Lärmschutzvorrichtungen an Straßen anzuwenden, die für den Einbau in die in EN ISO 10140-2 und EN ISO 10140-4 beschriebene Prüfeinrichtung geeignet sind.
Dieses Verfahren gilt nicht zur Bestimmung der produktspezifischen Merkmale der Luftschalldämmung von Lärmschutzvorrichtungen an Straßen unter nicht halligen Bedingungen.

Dispositifs de réduction du bruit du trafic routier - Méthode d'essai pour la détermination de la performance acoustique - Partie 2 : Caractéristiques intrinsèques de l'isolation aux bruits aériens dans des conditions de champ acoustique diffus

Le présent documentspécifie la méthode de laboratoire permettant de mesurer la performance d'isolation aux bruits aériens des dispositifs de réduction du bruit du trafic routier dans des conditions de réverbération. Elle traite de l'évaluation de la performance intrinsèque des écrans antibruit qui peuvent raisonnablement être assemblés à l'intérieur de l'installation d'essai décrite dans l'EN ISO 10140-2 et l'EN ISO 10140-4.
La présente méthode n'est pas destinée à la détermination des caractéristiques intrinsèques d'isolation aux bruits aériens des dispositifs de réduction du bruit devant être installés sur les routes dans des conditions non réverbérantes.

Protihrupne ovire za cestni promet - Preskusna metoda za ugotavljanje akustičnih lastnosti - 2. del: Karakteristike, značilne za izolacijo pred zvokom v zraku pri razpršenem zvočnem polju

Ta evropski standard določa laboratorijsko metodo za merjenje lastnosti za izolacijo pred zvokom v zraku pri protihrupnih ovirah za cestni promet v odmevnih pogojih. Zajema vrednotenje značilnih lastnosti ovir, ki jih je mogoče razumno zbrati v laboratoriju, opisanem v standardih EN ISO 10140-2 in EN ISO 10140-4.
Ta metoda ni namenjena ugotavljanju karakteristik, značilnih za izolacijo pred zvokom v zraku, pri protihrupnih ovirah za namestitev na cestah v neodmevnih pogojih.
