For design and verification of the Columbus APM (Attached Pressurized Module) subsystems against the in-orbit vibro-acoustic environment, Statistical Energy Analysis (SEA) is an approach particularly suited for the upper frequency range. During the space flight the equipment located inside the module (running subsystems and scientific experiments) will generate noise and vibrations. This permanent noise levels radiated in a reverberant cavity may produce undesired nuisance for the astronauts as well as perturbations in the microgravity experiments on board through the generation of induced vibrations. Therefore, the noise and vibration levels have to be predicted in order to be controlled. To comply with this objective a SEA analysis of the Columbus APM has been performed at the European Space Agency in cooperation with INTERAC, complemented with some FEM calculations to cover the low frequency regime.
