自然的被动机械系统，如耳鼓膜，可以通过结合反馈机制来显示主动响应，然后影响其机械结构。在本文中，蛾的听觉系统被用作灵感的生物模型。开发了一种改变其固有共振频率的智能声学系统。实验结果，给出了一个建议建立的实时嵌入式系统，显示时间和幅度依赖于动态频率适应根据声输入信号的强度。
Natural passive mechanical systems such as ear tympanic membranes may show active responses by incorporating feedback mechanisms which then affect their mechanical structure. In this paper, the moth's auditory system is used as a biological model of inspiration. A smart acoustic system which alters its natural resonance frequency was developed. Experimental results, given by a proposed-built real-time embedded system, show time and amplitude dependency towards dynamic frequency adaptation according to the intensity of acoustic input signals.
