This paper describes a new control algorithm for reducing pressure level of periodic sound. As the algorithm basically comes from the learning control that is invented for controlling the repetitive motion of robot, it is effective for reducing the periodic sound. In this paper a linear control system is supposed, which leads to a simple control gain matrix that relates the renewing control input with the error output. The condition to satisfy the convergence of the control output is investigated for the single input/single output control system consisted of the two degree system and the lag time system. This condition is proved by the numerical simulation.
