Abstract:

In this paper, the action mechanisms of porous sound absorbing materials, multi⁃layered sound absorbing materials, composite porous sound absorbing materials, single⁃layered sound insulating materials and multi⁃layered sound insulating materials were briefly introduced from the aspects of polymeric sound absorbing materials and sound insulating materials. Based on the limitations of the performance of existing materials, the preparation methods of polymeric composite soundproofing materials and the ways to improve their soundproofing performance were reviewed in detail. Moreover, through combining with the literature, the preparation methods and acoustic properties of layered composite noise⁃reducing materials, environmentally friendly composite noise⁃reducing materials, and acoustic metamaterials were introduced to provide a direction for the future improvement of noise⁃reducing polymeric materials. Finally, a brief outlook on the development prospects of high⁃noise composite materials was presented.

Key words: polymer, sound absorption, sound insulation, layered structure, environmental protection
