| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Pre-inverse type active noise control (ANC) estimates the inverse filter of a secondary path, and its filter is introduced before the secondary path, Thus, the ANC suppresses noise. However, the auxiliary noise is required in order to estimate the secondary path. However, the auxiliary noise causes the degradation of noise reduction performance. Therefore, in this paper, a power scheduling is introduced into an ANC based on a pre-inverse type structure. The paper method performs the power scheduling by two stages. In a first stage when the ANC starts and the path are changed after stopping, the ANC system injects the auxiliary noise according to the power ratio between input noise and error. In second stage when the adaptive filters converge enough, the ANC system stops injecting the auxiliary noise. Therefore, the noise reduction performance can be improved. | |
