ABSTRACT:
The vibration absorber for the absorption of structure-borne sound has a wave conducting element made of mass-spring elements layered on top of each other and extending in the wave propagation direction. The mass-spring elements are configured as bending beams or plates, with a resilience which decreases in the wave propagation direction. The mass-spring elements are connected with each other by spacers which are arranged offset in respect to each other, in such a way that when they are affected by pressure or pulling at least one mass-spring element is bent.
