ABSTRACT:
A method and an apparatus are disclosed serving to minimize acoustic emission of submerged submarines. Moving mechanical elements in an inner region give off vibrations onto an outer hull via a vibration transmission path. The vibrations are damped with damping means in the vibration transmission path. The damping means is configured as an evacuated intermediate space and is inserted in the vibration transmission path.
