Acoustics - Measurement of sound insulation in buildings and of building elements using sound intensity - Part 1: Laboratory measurements (ISO 15186-1:2000)

Akustik - Bestimmung der Schalldämmung in Gebäuden und von Bauteilen aus Schallintensitätsmessungen - Teil 1: Messungen im Prüfstand (ISO 15186-1:2000)

Der vorliegende Teil von ISO 15186 legt ein Schallintensitätsverfahren zur Bestimmung des Schalldämmmaßes und der Norm-Schallpegeldifferenz von Bauteilen fest. Das Verfahren kann alternativ zu ISO 140-3 bzw. ISO 140-10 eingesetzt werden. Das Verfahren wird insbesondere dann eingesetzt, wenn das herkömmliche Verfahren nach ISO 140-3 wegen hoher Flankenübertragung versagt.
Es wird abgeschätzt, dass die Reproduzierbarkeit dieses Intensitätsverfahrens gleich oder besser als das von ISO 140-3 ist.
ANMERKUNG   In Anhang A sind Angaben über die Genauigkeit enthalten, mit der der vorliegende Teil von ISO 15186 das nach ISO 140-3 gemessene Schalldämmmaß reproduzieren kann.

Acoustique - Mesurage par intensité de l'isolation acoustique des immeubles et des éléments de construction - Partie 1: Mesurages en laboratoire (ISO 15186-1:2000)

La présente partie de l'ISO 15186 spécifie une méthode d'intensité pour déterminer l'indice d'affaiblissement acoustique et l'isolement acoustique normalisé des éléments de construction. La méthode peut être utilisée comme une alternative à l'ISO 140-3 et à l'ISO 140-10 respectivement. L'utilisation de cette méthode se révèle importante lorsque la méthode traditionnelle de l'ISO 140-3 échoue en raison d'une transmission latérale élevée.La reproductibilité de cette méthode d'intensité est jugée supérieure ou égale à celle de l'ISO 140-3.NOTE Certaines informations relatives à l'exactitude avec laquelle la présente partie de l'ISO 15186 peut reproduire l'indice d'affaiblissement acoustique mesuré conformément à l'ISO 140-3 sont données dans l'annexe A.
