An elastic mounting comprises an elastic rubber spring member (3) located between two connecting members (1, 2) in order to support a vibrating load, whose vibration spectrum includes both low frequency and high frequency vibrations, in particular motor vehicle engine mountings. In parallel with the spring member (3) is fitted an electrostrictive or magnetostrictive actuator (4) in such a way that one face thereof (4.2) is rigidly coupled to a connecting member (1 or 2) of the spring member (3) while its other face (4.1) is connected to the other connecting member (2 or 1) via a closed static decoupling hydraulic system (11, 12). A sensor detects the alternating forces, alternating accelerations or vibrational displacements due to the vibrating load (L) and is connected to the actuator (4) via an amplitude and phase regulator and amplifier, wherein the regulation is so designed that the actuator (4) minimises the alternating forces, alternating accelerations and vibrational displacements applied to the sensor. The sensor may instead detect a characteristic parameter of a moving part of the vibrating load such as the angular position and/or rotation speed of an engine crankshaft. <IMAGE>
