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

This European Standard describes a test method for measuring a quantity representative of the intrinsic characteristics of airborne sound insulation for traffic noise reducing devices: the sound insulation index.
The test method is intended for the following applications:
-   determination of the intrinsic characteristics of airborne sound insulation of noise reducing devices to be installed along roads, to be measured either in situ or in laboratory conditions;
-   determination of the in situ intrinsic characteristics of airborne sound insulation of noise reducing devices in actual use;
-   comparison of design specifications with actual performance data after the completion of the construction work;
-   verification of the long term performance of noise reducing devices (with a repeated application of the method);
-   interactive design process of new products, including the formulation of installation manuals.
The test method is not intended for the determination of the intrinsic characteristics of airborne sound insulation of noise reducing devices to be installed in reverberant conditions, e.g. inside tunnels or deep trenches or under covers.
Results are expressed as a function of frequency in one-third octave bands, where possible, between 100 Hz and 5 kHz. If it is not possible to get valid measurement results over the whole frequency range indicated, the results need to be given in a restricted frequency range and the reasons for the restriction(s) need to be clearly reported.

Lärmschutzvorrichtungen an Straßen - Prüfverfahren zur Bestimmung der akustischen Eigenschaften - Teil 6: Produktspezifische Merkmale - In-situ-Werte der Luftschalldämmung in gerichteten Schallfeldern

Diese Europäische Norm beschreibt ein Prüfverfahren zur Messung einer Größe, die für die produkt-spezifischen Merkmale der Luftschalldämmung von Lärmschutzvorrichtungen charakteristisch ist: den Schall-dämmungsindex.
Das Prüfverfahren ist für die folgenden Anwendungen vorgesehen:
   Bestimmung der produktspezifischen Merkmale der Luftschalldämmung von Lärmschutzvorrichtungen, die entlang von Straßen einzubauen sind und die in situ oder unter Prüfstandbedingungen zu messen sind;
   Bestimmung der in situ gegebenen produktspezifischen Merkmale der Luftschalldämmung von Lärm-schutzvorrichtungen im tatsächlichen Einsatz;
   Vergleich der Bemessungsfestlegungen mit den tatsächlichen Leistungsdaten nach Abschluss der Bau-arbeiten;
   Überprüfung der Langzeitwirksamkeit von Lärmschutzvorrichtungen (durch wiederholtes Anwenden des Verfahrens);
   einen interaktiven Bemessungsprozess von neuen Produkten, einschließlich der Formulierung von Einbauanleitungen.
Das Prüfverfahren ist nicht für die Bestimmung der produktspezifischen Eigenschaften der Luftschalldämmung von Lärmschutzvorrichtungen, die in halligen Schallfeldern einzubauen sind, z. B. innerhalb von Tunneln, in ausgeprägten Tieflagen oder unter Abdeckungen.
Ergebnisse werden als Funktion der Frequenz in Terzbändern zwischen 100 Hz und 5 kHz angegeben, wo möglich. Falls kein gültiges Messergebnis über den gesamten Frequenzbereich zu gewinnen ist, müssen die Ergebnisse im eingeschränkten Frequenzbereich zusammen mit den Gründen der Ein¬schrän¬kung(en) klar angegeben werden.

Dispositifs de réduction du bruit du trafic routier - Méthode d'essai pour la détermination de la performance acoustique - Partie 6: Caractéristiques intrinsèques - Valeurs in situ d'isolation aux bruits aériens dans des conditions de champ acoustique direct

La présente Norme européenne décrit une méthode d'essai permettant de mesurer une grandeur représentative des caractéristiques intrinsèques de l'isolation aux bruits aériens des dispositifs de réduction du bruit du trafic routier : l'indice d'isolation acoustique.
La méthode d'essai est destinée aux applications suivantes :
   la détermination des caractéristiques intrinsèques d'isolation aux bruits aériens de dispositifs de réduction du bruit destinés à être installés le long des routes, à mesurer sur site ou dans des conditions de laboratoire ;
   la détermination des caractéristiques intrinsèques sur site d'isolation aux bruits aériens de dispositifs de réduction du bruit en service ;
   la comparaison des spécifications de conception avec des données de performance réelles de l'ouvrage de construction achevé ;
   la vérification des performances à long terme de dispositifs de réduction du bruit (par l'application répétée de la méthode) ;
   un processus interactif de conception de nouveaux produits, y compris la formulation des manuels d'installation.
La méthode d'essai n'est pas destinée à la détermination des caractéristiques intrinsèques d'isolation aux bruits aériens de dispositifs de réduction du bruit destinés à être installés dans des conditions réverbérantes, par exemple à l'intérieur de tunnels ou de tranchées profondes ou sous des couvertures.
Les résultats sont exprimés en fonction de la fréquence, par bandes de tiers d'octave, si possible, entre 100 Hz et 5 kHz. S'il est impossible d'obtenir des résultats de mesure valables sur toute la plage de fréquences indiquée, les résultats doivent être donnés pour la plage de fréquences réduite et les raisons de la ou des restriction(s) doivent être clairement consignées.

Protihrupne ovire za cestni promet - Preskusna metoda za ugotavljanje akustičnih lastnosti - 6. del: Bistvene lastnosti - Terenske vrednosti izolirnosti pred zvokom v zraku

Ta evropski standard opisuje preskusno metodo za merjenje količine, ki predstavlja bistvene lastnosti na področju izolirnosti pred zvokom v zraku pri protihrupnih ovirah za cestni promet: indeksa izolirnosti pred zvokom. Preskusna metoda je namenjena: – ugotavljanju bistvenih lastnosti na področju izolirnosti pred zvokom v zraku pri obcestnih protihrupnih ovirah, ki se merijo na kraju samem ali pod laboratorijskimi pogoji; – ugotavljanju bistvenih lastnosti na področju izolirnosti pred zvokom v zraku pri protihrupnih ovirah med dejansko uporabo na kraju samem,; – primerjavi specifikacij zasnove s podatki o dejanskih lastnostih po koncu gradnje; – preverjanje dolgoročnih lastnosti protihrupnih ovir (z večkratno izvedbo metode); – interaktivnemu postopku zasnove novih izdelkov, vključno s pripravo navodil za namestitev. Preskusna metoda ni namenjena ugotavljanju lastnosti, bistvenih za izolacijo pred zvokom v zraku, pri protihrupnih ovirah za namestitev v odmevnih pogojih, npr. v predorih ali pod pregradami. Rezultati so izraženi kot funkcija frekvence v tretjinskih oktavnih pasovih med 100 Hz in 5 kHz, kadar je to mogoče. Če ni mogoče dobiti veljavnih rezultatov meritev za celo opredeljeno frekvenčno območje, se rezultati navedejo za omejeno frekvenčno območje, razlog(-i) za omejitev območja pa jasno opredelijo.
