In this paper,we propose an control method of feedback which occurs on active noise control systems.
On active noise control systems, if back path occurs,the sound emitted from a speaker is detected by a noise detection microphone,therefore it causes howling,and failure of a speaker.
In order to solve this problem,we use that we can calculate primary path and secondary path.
In this paper,we present a method that we calculate the identification error of feedback path and feedback control filter using that result,and add the error to feedback control filter coefficient,and finally verify the validity of them by the simulations using actual impulse responses. |
