Adaptive Algorithm Noise control has been developed to establish the comfortable soundscape even if our house life. Floor impact noise such as the sound of footsteps or falling object becomes a problem in an apartment house. Floor impact noise has a peak at the low-frequency range. Passive noise control is not effective against low-frequency noise. Therefore, the purpose of this paper is to control the impact noise using active noise control. Since each impact noise is generated in a short period, LMS algorithm is difficult to use because of its slow convergence characteristics. On the other hand, frequency domain adaptive algorithm is known for fast convergence characteristics. In this paper, the effectiveness of active noise control using frequency domain adaptive algorithm is confirmed through simulations and experiments.
