Various acoustic materials have been developed to resolve noise pollution problem in many industries. Especially, materials with porous structure have been broadly used to absorb sound energy in civil construction and transportation area. Polyurethane (PU) porous materials possess excellent damping properties, good toughness and well‐developed pore structures, which have a broad application prospect in sound absorption field. This work aimed to summarize the recent progress of fabrication and structure for PU porous materials in sound absorption application. The sound absorption mechanisms of porous materials were introduced. Different kinds of structure for typical PU porous materials in sound absorption application were covered and highlighted, which included PU foam, modified PU porous materials, aerogel, templated PU and special PU porous materials. Finally, the development direction and existing problems of PU material in sound absorption application were briefly prospected. It can be expected that porous PU with high sound absorption coefficient can be obtained by using some facile methods. The design and accurate regulation of porous structures or construction of multilayer sound absorption structure will be favorably recommended to fulfill the high demand of industrial and commercial applications in the future work.This article is protected by copyright.
