Abstract
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. In our previous research, the situation of fixed vibration source and control point was considered. In this paper, we consider about changing vibration source and control point. First, this research focus on changing control point. In this paper, the effectiveness of active noise control using frequency domain adaptive algorithm with processing that compute the control noise through the use of vibration modes is confirmed through simulations.
