Abstract: The process of natural fibrematerials in the structures has substantial quantity of attention recently. Presently, few reports present on sound and vibration damping frequency properties in natural fibres materials reinforced composites. In this chapter, the sound and vibration frequency properties of damping of natural material based composites aredistinguished. It was noticed that utilizing a natural (flax) fiber material reinforced composites has 33.8% improvement in vibration damping properties, when compared with glass fibre reinforced composites. Sound wave absorption coefficient of natural material (flax) reinforced composite has also improved 17.64% and 20% at higher and lower operating frequency levels respectively when related to glass fiber reinforced composites. These answer suggest that, natural fibermaterial based composites could be annext solution for environmentally friendly to observe the vibration and noise radiation problem.
