This paper proposes a method of noise reduction by controlling the vibration of a wall between two rooms by an active control device. This is done by using an additional sensor to measure the wall vibration and feed it back to the controller. The board speaker is used primarily to generate sound by exciting the board. However, in this study, it is used as an active vibration control device. The performance of the device is tested on a panel made from a veneer board 1200 x 900 x 5 mm in size which is exposed to sound vibration from the other speaker. The evaluation of this method is performed experimentally by comparison of the dynamic deflection of the panel with and without the device. The experimental results show a significant reduction level to 1/10 of the panel dynamic deflection at frequencies below 100 Hz. The effectiveness of the method is confirmed theofetically by simulation studies. Also, the stability of the control system using the active control device is examined through the root locus method.
