An apparatus for attenuating vibration transmission between first and second structures includes a rod extending entirely through, and being mechanically connected to, both of the first and second structures. The rod defines a central longitudinal axis. A piezoelectric sensor senses vibrations in at least one of the first and second structures and responsively generates a voltage. The piezoelectric sensor is disposed entirely longitudinally between the first and second structures. A piezoelectric actuator actively attenuates the vibrations sensed by the piezoelectric sensor. The piezoelectric actuator is at least partially driven responsive to voltage generated by the piezoelectric sensor. The piezoelectric actuator is disposed entirely longitudinally between the first and second structures. At least one of the piezoelectric sensor and the piezoelectric actuator has a throughhole through which the rod entirely extends.
