There are many noise sources around us even in the room such as an office room. Both simple and effective noise shielding devices are expected in such a room. As a practical active noise control device, an active noise shielding system is proposed in this paper. This active noise shielding system consists of microphones, a loudspeaker, controller and a general partition used in an ordinary office. Firstly, passive noise control effect with partition itself is investigated by numerical analysis and experiments. Next, active noise control effect with proposed active noise shielding system is confirmed through simulations and experiments.
