摘　　要：噪声污染问题不但制约着经济的发展,还严重影响着人们的身心健康,因此如何有效地控制噪音,开发出降噪性能优异的吸声材料是一个十分重要且亟待解决的课题。本文从纤维类吸声材料的发展出发,重点论述了该类材料的一个重要分支-聚合物纤维类吸声材料的研究现状,同时结合吸声机理及影响吸声性能因素,阐述了聚合物纤维类吸声材料的结构与其声学性能的相互关系,并展望了其发展趋势。Noise pollution is becoming a serious problem due to its great adverse effects on the development of economy and human health. Therefore, how to control the noise and develop excellent sound absorption materials to prevent the noise pollution is an important and urgent issue. Recent progress in sound absorption materials based on polymer fibers is reviewed. This paper begins with the development of acoustical fibers, and then focuses on the research of polymer fibers. The sound absorption mechanism, the influence factors in acoustic performance and the relationship between the structure and acoustic properties of the polymer fibers are introduced. The prospect of these materials is proposed.
