摘　　要：概述了以聚氨酯基体为主要应用的水下吸声材料,主要阐述了水声机理、常用的水声吸声材料与结构,以及以局域共振声子晶体为基础衍生出的新型水下吸声材料结构,如声子晶体、局域共振声子木堆、超材料吸声结构,为未来水声吸声材料的发展提供了更广阔的发展空间及方向。The underwater sound-absorbing materials with polyurethane matrix as the main application are outlined,and the mechanism of underwater sound and general underwater acoustic absorption materials and these structure are mainly explained.The structure of a new type of underwater sound-absorbing material derived from local resonant phononic crystals is described,such as phononic crystals,local resonance phonon woodpile,and metamaterial sound-absorbing structures,which provides a broader development space and direction for the development of underwater sound-absorbing materials in the future.
