An account of a series of structural acoustics tests in the Large European Acoustic Facility (LEAF) and a summary of the main findings are presented. These investigations were part of the LEAF commissioning phase. Essentially, they provided a 'dress rehearsal' for the test facility operators prior to project use and enabled practical handling of structures, checking microphone and accelerometer systems and additional siren operation practice. It also provided an opportunity to investigate the acoustical properties of an Ariane fairing (half) enclosure and their impact on structural samples. The findings demonstrated the generally reverberant nature of the enclosure and the rather small effect of local additional (reflecting) structural elements on specimen response behavior.
