This review article provides a comprehensive overview of fiber and nanoparticle reinforced polymer matrix composites (PMC) for their damping and sound absorption properties. It explains the mechanism of damping and sound absorption properties of the material as a first step. Further, the paper discusses the governing parameters of materials responsible for the variation of the material's damping and sound absorption properties. The performance of damping and sound absorption properties of different fibrous materials, including natural fibers, synthetic fibers, and different nanoparticles, including carbon nanotube, graphene nanotubes-based PMC are reviewed. The role of the interfacial region, density, fiber thickness, porosity, viscoelasticity, and friction on the damping and sound absorption properties has been discussed. The sound absorption properties of much denser, thicker, and more porous materials are higher than those of less dense, thinner, and less porous materials because of their higher polymerization. The damping performance of the PMC was observed to be increased with the decrease in the bonding of the interface region between fiber and matrix. The conclusion of this review provides several useful recommendations for the further development of PMC with the desired damping and sound absorption properties.
