Abstract:	Gegenstand dieser Arbeit ist die Untersuchung des Bemessungsansatzes der VDI-Richtlinie VDI 2719:1987-08 für den Schallschutz von Fenstern unter Berücksichtigung aktueller Außenlärmpegelspektren des Bahn- und Fluglärms. Das Leitmotiv stellt die Problematik der heute in der Praxis festgestellten Fehlbemessung des Schallschutzes bei Verwendung der in VDI 2719 enthaltenen Korrektursummanden dar. Der Ansatz zur Verwendung verschiedener Korrektursummanden in VDI 2719:1987-08 basiert auf einer 1985 vom Umweltbundesamt in Auftrag gegebenen Forschungsarbeit von Moll und Szabunia. Die K-Summanden berücksichtigen sowohl die Frequenzabhängigkeit der Fenster-Schalldämmung als auch der Spektren des Außenlärms, welche sich beide im Laufe der Zeit verändert haben. Mit dieser Arbeit soll eine Basis geschaffen werden, auf der - anhand heute typischer Konstruktionen und Außenlärmsituationen - die erforderliche Schalldämmung der Fenster ohne erhebliche Über- oder Unterbemessung des Schallschutzes ermittelt werden kann. Investigation of the design approach of German standard VDI 2719 for the sound absorption of windows, taking into account current spectra of railway and aircraft noise. The purpose of this work is to examine the design approach of the German standard VDI 2719:1987-08 for the sound insulation of windows, taking into account the current level of railway and aircraft noise. The practical problem of the noise protection design lack when using the correction sum-mands (K-summands) following VDI 2719 is dis-cussed. This approach was based on research results from 1985 work by Moll and Szabunia, commissioned by the German Umweltbundesamt (UBA). The K-summands take into account both the frequency dependence of the window sound absorption and the spectra of the external noise, which have both changed over time. The aim of this thesis is to provide a basis on which the necessary sound absorption of the windows can be determined without considerable over- or under-dimensioning, and using today's typical construc-tions and external noise situations.
