【摘要】 噪音污染已经成为一种主要污染源，对人们的生活质量产生了严重影响，降噪材料的研究也日益得到重视。纤维材料作为典型的多孔吸声材料，其降噪性能一直被人们关注，文中综述了不同种类纤维材料在降噪方面的优势与劣势、纤维材料降噪后的处理手段与纤维材料结构体的设计这3个方面，以期为使用纤维材料构建具有更高效吸声性能的结构体提供新思路。更多还原

【Abstract】 Noise pollution has become a major source of pollution, which has a serious impact on people’s quality of life. Research on noise-reducing materials is also receiving increasing attention. As a typical porous sound-absorbing material, the noise reduction performance of fiber material has always attracted attention. The advantages and disadvantages of different types of fiber materials in noise reduction, the noise reduction post-treatment methods of fiber materials and the design of fiber material structure are reviewed, in order to provide new ideas for the use of fiber materials to build structures with more efficient sound absorption performance.更多还原
