| 中文摘要: |
| 本文用传递函数描述了复合式有源消声耳罩的系统模型，确定了模拟式消声控制器的合理阶次。对于前债控制器和反馈控制器，均给出了成熟的电路实现方案。最后，实际设计了复合式有源消声耳罩，并实测了控制器特性和消声效果，验证了本文提出的控制器实现方法的有效性． |
| 英文摘要: |
| A system model of a compound active noise-cancellation earmuff(CANCE) is described by means of transfer function, and the optimal order of the controllers is discussed. Practical circuits are given to implement both the feedforward controller and the feedback controller. A practical CANCE is fabricated, and the noise cancellation effect is tested, so that the effectiveness of the inplementation method is verified. |
