ABSTRACT OF THE DISCLOSURE A vibration-damping arrangement comprises a chamber containing gas at a pressure above atmospheric pressure. Vibrations from a machine are supplied to a wall section made of flexible rubber or the like and a rigid section is in contact with the person to be protected. To achieve a pressure rise in the chamber corresponding to the amplitude of the vibra- tions, the flexible section is non-stretchable. The amplitude-dependent pressure rise implies absorption of energy also within a low-frequency range.
