| 摘 要： | 声学超构材料的概念起源于局域共振型声子晶体。作为一种新型复合人工结构材料,声学超构材料具备许多优异的特性,如相对于传统隔声材料可以灵活、精准地操控声波,采用小型化、轻质化的结构解决宽频带、低频隔声等问题。本文综述了声学超构材料在隔声方面的最新研究进展,从带隙理论和表征参数出发论述了声学超构材料隔声机理,重点介绍了相关代表性工作,包括Helmholtz式隔声超构材料、薄膜薄板式隔声超构材料、折叠卷曲空间式隔声超构材料以及组合式隔声超构材料的设计理念和方法,最后对这一新兴领域的应用进行了展望。

| Abstract: | The concept of acoustic metamaterials originated from local resonance phononic crystals. As a new type of composite artificial materials, acoustic metamaterials have excellent special properties. For example, compared with conventional sound insulation materials, they can manipulate sound waves flexibly and accurately, and use small and lightweight structure to solve broadband low-frequency sound insulation. In this paper, the latest research progresses of acoustic metamaterials in sound insulation and noise reduction are reviewed. Based on bandgap theory and equivalent parameters, the sound insulation mechanism is discussed, and the related work is introduced in detail, including Helmholtz, membrane, space-coiling and composite sound insulation metamaterials. Finally, the application of this new field is predicted. |
