Claim 10:
11. A rearview assembly comprising:
a sub-assembly whose components are physically coupled and vibrate substantially synchronously, the sub-assembly comprising a display element, the display element operable to receive and display an image of a scene rearward a vehicle;
an array of piezo-electric sensors coupled to the sub-assembly such that they vibrate substantially synchronously, the array comprising at least one piezo-electric sensor in each of an x, y, and z direction, each piezo-electric sensor operable to output:
a first signal based, at least in part, on sensing a first vibration, and
a second vibration in response to receiving a second signal; and

a controller communicatively connected to the array of piezo-electric sensors, the controller operable, for each of the piezo-electric sensors, to:
receive the first signal,
generate the second signal based, at least in part, on the first signal, the second signal determining the second vibration, the second vibration substantially out of phase with the first vibration, and
communicate the second signal to the piezo-electric sensor;
wherein the second vibration is operable to substantially dampen the first vibration.
