Abstract
Deutsch: Eine Doppelschale wird experimentell hinsichtlich ihrer modalen Eigenschaften, des Einflusses der Sekundärschale auf die Primärschale, des Einflusses des Schalenabstandes auf die Sekundärschalen-Schwingungen und der Mass-Air-Mass-Resonanz untersucht. Zusätzlich werden verschiedene Varianten der Doppelschale betrachtet, um Aussagen zum Transferverhalten zu treffen. Am Ende der Arbeit werden noch die Laufzeiten des Luftpfades und des Lagerpfades und das Feedback-Verhalten einer gedämmten Doppelschalen-Kavität unter-sucht. English: A double-leaf partition is experimentally investigated in focus of her modal properties, the influence of the second leaf relating to the prime leaf, the influence of the gap concerning the vibrations of the second leaf and the mass-air-mass resonance. Additionally there were tested several versions of the double-leaf partition to address the transfer behaviour. At the end of the thesis there also investigations in run-time of air and structural path and the feedback behaviour of dam double-leaf partition.
