摘要
提出了设计参数与具体配戴无关的双传声器自适应有源消声耳罩，给出了有源消声耳罩的结构和原理，理论和实验表明，其在较宽频率范围有较好消声效果，且具有不依赖具体佩戴状态的良好适应性．
An adaptive and active ear muffle is proposed, which has two microphones, one for reference and the other for residue sound. The muffler has excellent and wide range of noise suppression effect independent of wearing state. Its structure, principle and experimental results are described in the paper.
