摘要：
我们提出了一个设计的声学超材料，模仿的行为，积极的耳蜗。这种材料由圆柱形亚波长谐振器的大小分级阵列组成，具有与耳蜗相似的尺寸，并且能够再现可听频率的频率分离。为了复制耳蜗放大器的行为，将非线性放大引入模型。该制剂的形式的流体耦合阵列的霍普夫谐振器。我们寻求基于模式分解的解决方案，以保持谐振器之间的物理导出的耦合。
英文摘要：
We present a design for an acoustic metamaterial that mimics the behaviour of the active cochlea. This material is composed of a size-graded array of cylindrical subwavelength resonators, has similar dimensions to the cochlea and is able to reproduce the frequency separation of audible frequencies. Non-linear amplification is introduced to the model in order to replicate the behaviour of the cochlear amplifier. This formulation takes the form of a fluid-coupled array of Hopf resonators. We seek solutions based on a modal decomposition, so as to retain the physically-derived coupling between resonators.
