An approach for active noise control using structural vibration was proposed. No acoustic instruments such as loud speakers and microphones are necessary in this approach. The adaptive FIR filter using the LMS algorithm was used in the control system. Both a computer simulation and an experiment were carried out. The importance of using a howling canceler with the adaptive FIR filter was shown by the simulation. In the experiment, the vibration of the sidewalls of the duct was used for control. Good results were acquired using the simple controller.
