Abstract
A vibration damping device for a body resonant at two frequencies, is formed by a plate which can be connected to the body transversely with respect to its vibration direction. A post extends from the plate and mounts one end of an elastically flexible tongue which extends from the post substantially parallel to the plate so as to form a space between the tongue and plate. A weight is fixed to the other end of the tongue and vibration damping material is positioned in the space. The tongue and weight form a system resonant at both of the bodies' resonant frequencies, the tongue's energy being absorbed by the damping material.
