There are many noise sources around us. Floor impact noise such as the sound of footsteps and falling object becomes a problem in an apartment house. Floor impact noise has a peak at the low-frequency range and passive noise control for floor impact noise is difficult to control. Therefore, the purpose in this paper is control the impact noise with active noise control. Since the impact noise comes separately, active noise control with LMS algorithm based on the steepest descent method is difficult to the extent of slow convergence characteristics. In this paper, the effectiveness of active noise control using frequency domain adaptive algorithm that has fast convergence characteristics is confirmed through simulations and experiments.
