Acoustics - Test code for suspended ceilings - Sound absorption

This European Standard specifies additional necessary information on how to carry out efficiently and under standardized conditions the determination of the sound absorption coefficients according to EN ISO 354 “Measurement of sound absorption in a reverberation room”. It specifies the additional requirements of the sound absorption measurements and the operating and mounting conditions that should be used for the test. Observe that all demands in EN ISO 354 still should be fulfilled. The results obtained are used for design calculations with respect to room acoustics and to convert frequency-dependent sound absorption coefficients into a weighted sound absorption coefficient αw, according to EN ISO 11654.
This European Standard is applicable for the compile of the single number rating αw, to express the sound absorption performance of suspended ceiling membranes in CE marking and labelling according to EN 13964. This European Standard is not applicable for suspended ceiling kits according to EN 13964.

Akustik - Prüfvorschrift für Unterdecken - Schallabsorption

Diese Europäische Norm legt zusätzliche, notwendige Informationen dazu fest, wie Schallabsorptionsgrade nach EN ISO 354, Akustik — Messung der Schallabsorption in Hallräumen effizient und unter genormten Bedingungen ermittelt werden. Sie legt zusätzliche Anforderungen an die Messung der Schall¬absorption sowie an Betriebs- und Befestigungsbedingungen, die während der Prüfung gelten sollten, fest. Es ist zu beachten, dass sämtliche Forderungen von EN ISO 354 erfüllt sein sollten. Die erzielten Ergebnisse werden für Konstruktionsberechnungen hinsichtlich der Raumakustik genutzt und um frequenzabhängige Schall-absorptionsgrade nach EN ISO 11654 in einen bewerteten Schallabsorptionsgrad αw umzurechnen.
Diese Europäische Norm ist bei der Zusammenstellung der Einzahlbewertung αw anwendbar, um nach EN 13964 die schallabsorbierende Leistung von Decklagen bei Unterdecken für CE-Kennzeichnung und Etikettierung anzugeben. Diese Europäische Norm ist nicht auf Unterdeckenbausätze nach EN 13964 anwendbar.

Acoustique - Code d'essai des plafonds suspendus - Absorption acoustique

La présente Norme européenne fournit les informations supplémentaires nécessaires pour déterminer efficacement et dans des conditions normalisées les coefficients d'absorption acoustique selon l'EN ISO 354 « Mesurage de l'absorption acoustique en salle réverbérante ». Elle spécifie les exigences supplémentaires des mesurages d'absorption acoustique et des conditions de fonctionnement et de montage qu'il convient d'utiliser pour l'essai. Il est à noter qu'il convient que toutes les exigences de l'EN ISO 354 soient toujours satisfaites. Les résultats obtenus sont utilisés pour les calculs de conception relatifs à l'acoustique des salles et pour convertir les coefficients d'absorption acoustique dépendants de la fréquence en un coefficient d'absorption acoustique pondéré, αw, selon l'EN ISO 11654.
La présente Norme européenne est applicable à la détermination de la valeur unique, αw, pour exprimer la performance d'absorption acoustique des membranes de plafonds suspendus dans le marquage CE et l'étiquetage conformément à l'EN 13964. La présente Norme européenne n'est pas applicable aux kits de plafonds suspendus selon l'EN 13964.

Akustika - Preskusni postopek za viseče strope - Absorpcija zvoka

Ta evropski standard določa dodatne potrebne informacije, kako učinkovito in pri standardnih pogojih določiti koeficiente absorpcije zvoka po standardu EN ISO 354 »Merjenje absorpcije zvoka v odmevnici«. Določa dodatne zahteve za merjenje absorpcije zvoka ter zahteve za delovanje in priključitev, ki jih je treba uporabiti za preskus. Upoštevati je treba, da morajo biti še vedno izpolnjene vse zahteve iz standarda EN ISO 354. Dobljeni rezultati se uporabljajo za projektne izračune v zvezi z akustiko v prostoru in za pretvarjanje koeficientov absorpcije zvoka, odvisnih od frekvence, v uteženi koeficient absorpcije zvoka w po standardu EN ISO 11654. Ta evropski standard se uporablja za določanje enomestne številske stopnje w za izražanje akustičnih lastnosti membran visečih stropov z oznako CE in oznako po standardu EN 13964. Ta evropski standard se ne uporablja za opremo za viseče strope po standardu EN 13964.
