A damping device is described that is designed to counter the transmission of vibrations to a further element and comprises: a beam element, which extends mainly parallel to an axis, is constrained to the further element and is designed to flexurally oscillate, in use, in a plane parallel to the axis to counter the transmission of vibrations to the further element; an actuator, which comprises a transmission element operatively connected to the beam element and extending mainly along the axis; the actuator being controllable to apply a direct tensile or compressive load along the axis on the transmission element that is variable according to the frequency of the vibrations to be dampened.
