The inventively advanced mount accommodates a conventional mount (such as an air mount) so as to include, at the mount's foundation-securing plate, at least one motion sensor and at least one vibratory actuator. Each sensor is correlated with an actuator. For each sensor-actuator pair, the electrical feedback loop includes generation by the sensor of a signal resulting from the local vibration of the foundation-securing plate, generation by a processor/controller of a signal derived from the sensor's signal, and exertion upon the foundation-securing plate by the sensor's paired actuator of a vibratory force commanded by the processor/controller's signal. Many preferred inventive embodiments collocate each sensor with its paired actuator and implement a conventional vibration suppression algorithm involving collocated velocity feedback. The inventive "passive-active" mount uniquely brings to bear, sequentially and complementarily, passive vibration control followed by active vibration control.
