The invention relates to reducing cabin noise caused by vibrations. In order to provide a facilitated noise reduction in aircrafts, a vibro-acoustic reduction system (10) on-board an aircraft is provided that comprises a plurality of frame elements (12) forming at least a part of a fuselage structure, a plurality of vibration dampening components (14), and a plurality of coupling interfaces (16) for attaching the vibration dampening components to the frame elements. The frame elements are provided with the plurality of coupling interfaces as pre-configured ready-for-use connection points (18) for an optional attachment of one of the vibration dampening components in dependency of an actual demand. Further, each of the vibration dampening components is provided with a mounting interface (20), and the vibration dampening components are attachable to the coupling interfaces of the frame elements with the mounting interfaces for different dampening measures scenarios.
