| Abstract: | This paper describes mainly some explorations in active noise control and discusses its feasibility in the rang of large frequency. Morever it tries to design the active ridding noise circuit. The writer realizes 3db ridding noise form 320Hz to 520Hz with the single-pass active ridding noise circuit, imitates this circuit, and analyses it theoretically. At last, the writer has given some advice to the improvement of active noise control and made some forecast. |
