Abstract
On active noise control in 3-dimensional acoustic field, a control effect reduces when an evaluation point moves. Against this problem, we proposed control with filter map. In this algorithm, a control area is divided into small grids. Adaptive filters are accumulated and corresponding to the node. The controller is updated from the accumulation. Effectiveness of this algorithm was shown in simulations. In this paper, the validity of this algorithm is shown in several simulations and experiments in an anechoic chamber. The evaluation point moves 0.4m at the speed of 0.45m/s in experiment. A CCD camera detects a position of the point. From the experimental results, it is shown that the effectiveness of the proposed algorithm is 10dB more than the that of the direct adaptive algorithm.
