1. A vibration reducing material comprising: a foam material layer comprising a plurality of projecting sections made of substantially rigid foam material and areas of predetermined weakness located within the foam layer between the projections to allow the vibration-reducing material to flex along such areas of predetermined weakness, the areas of predetermined weakness comprising grooves that form polygon shapes,a continuous, uniform elastomeric material layer configured to absorb vibration, andan aramid material layer that distributes vibration to facilitate vibration dampening, the aramid material layer defining a major material surface and being located between the foam and elastomeric layers, the aramid material layer being generally non-elastic in a direction generally perpendicular to the major material surface. 2. The vibration-reducing material of claim 1, wherein the polygon shapes are selected from the group consisting of: hexagons, diamonds, octagons, circles, ellipses, and combinations thereof. 3. The vibration-reducing material of claim 1, used as a protective pad. 4. The vibration-reducing material of claim 1, used as a protective pad to dissipate vibration from an impact and impact energy. 5. The vibration-reducing material of claim 1, wherein the foam material layer is substantially flexible. 6. The vibration-reducing material of claim 1, wherein each projecting section has a curvilinear surface with smooth edges. 7. The vibration-reducing material of claim 1, wherein each projecting section has a smooth parabolic surface. 8. The vibration-reducing material of claim 1, the foam material layer further comprising a plurality of U-shaped depressions between adjacent projecting sections, each depression having a bottom edge and substantially parallel side edges.
