Abstract

Considering about practical use of active noise control in 3dimensional sound field, it is difficult to obtain characteristic of a secondary path (acoustic path from the secondary source to the error microphone) beforehand. In this paper, a FTF algorithm that has fast converging property is newly introduced to a direct adaptive algorithm which does not need the secondary path characteristic beforehand. A numerical simulation is carried out with a sound field that the error path changes during control. Experiments are also carried out. The effectiveness of the proposed algorithm is shown through both the simulations and the experiments.
