1. A vehicle seat vibration dampening system comprising:
a vibration sensor that senses vibration of a vehicle seat generated by movement of a vehicle on a roadway, wherein the vibration sensor generates a signal indicative of the sensed vibration;
a controller that determines, based on the signal generated by the vibration sensor, a counter vibration to dampen the sensed vibration of the vehicle seat and, based on the determination, produces a control signal to effect generation of the counter vibration; and
a transducer that generates the counter vibration of the vehicle seat in response to the control signal to dampen the sensed vibration of the vehicle seat.
