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.
