1. An absorbent covering having high damping power, secured on a structure and comprising a dissipater mesh made up of a plurality of dissipating elements and of nodes each having its bottom end secured on said structure wherein said bottom ends of said nodes project from said dissipating elements so as to leave an empty space between the dissipating elements and said structure, said absorbent covering including main absorbent elements arranged in said empty space, each of said main absorbent elements being secured firstly to a bottom face of a said dissipating element and secondly to said structure, the dissipating elements cooperate to form laterally spaced empty spaces therebetween, each laterally spaced empty space not being filled with material. 2. A covering according to claim 1, wherein the dissipating elements are rigid relative to the absorbent elements and are made of a material forming part of the group comprising plastics materials. 3. A covering according to claim 1, wherein the dissipating elements are used in their elastic deformation range. 4. A covering according to claim 1, wherein said main absorbent elements are elastic and are made of a material forming part of the group of materials comprising elastomers. 5. A covering according to claim 1, wherein said main absorbent elements possess high energy absorption capacity relative to the dissipating elements. 6. A covering according to claim 1, wherein said main absorbent elements have a loss angle of at least 10°. 7. A covering according to claim 1, wherein the contact surface of said bottom end is covered with a self-adhesive material. 8. A covering according to claim 1, wherein said dissipater mesh has a repeated square pattern. 9. A covering according to claim 1, wherein said dissipater mesh has a repeated triangle pattern. 10. A covering according to claim 1, wherein at least one dissipating element is shaped in an ellipse. 11. A covering according to claim 10, wherein said ellipse is secured to two nodes disposed at the intersections between its periphery and its major axis. 12. A covering according to claim 10, wherein said dissipater mesh has a repeated triangle pattern, and said dissipater mesh comprises triangular portions each provided with three half-ellipses interconnected by three node fractions, each half-ellipse corresponding to an ellipse cut in half along its major axis. 13. A covering according to claim 12, wherein each half-ellipse of a triangular portion presents a concave side on the outside of said triangular portion. 14. A covering according to claim 12, wherein each node fraction corresponds to one-sixth of a node, said fraction occupying a sector of 60°. 15. An absorbent covering having high damping power, secured on a structure and comprising a dissipater mesh made up of a plurality of dissipating elements and of nodes each having its bottom end secured on said structure wherein said bottom ends of said nodes project from said dissipating elements so as to leave an empty space between each of the dissipating elements and said structure, said absorbent covering including a plurality of main absorbent elements, each of said main absorbent element being arranged in said empty space secured firstly to a bottom face of a respective one of said dissipating elements and secondly to said structure, said absorbent covering including secondary absorbent elements, each secondary absorbent element being arranged on top of one of said dissipating element so as to cover said dissipating element over the length of said dissipating element. 16. A covering according to claim 15, wherein each secondary absorbent element is made from an elastic material that gives it high capacity for absorbing energy compared with the dissipating elements by having a large loss angle of at least 10°. 17. A covering according to claim 15, including a rigid cover plate, said secondary absorbent elements then being arranged between said dissipating elements and said rigid cover plate. 18. A covering according to claim 1, wherein said dissipater mesh is machined as a single piece from a single block of deformable material. 19. A covering according to claim 1, wherein said dissipater mesh is obtained by molding of a block of deformable material as a single piece. 20. An absorbent covering having high damping power, secured on a structure and comprising a dissipater mesh made up of a plurality of dissipating elements and of nodes each having its bottom end secured on said structure wherein said bottom ends of said nodes project from said dissipating elements so as to leave an empty space between the dissipating elements and said structure, said absorbent covering including main absorbent elements arranged in said empty space, each of said main absorbent elements being secured firstly to a bottom face of a said dissipating element and secondly to said structure, wherein said dissipating elements and said main absorbent elements are elliptical in shape, each dissipating element covering a main absorbent element over its entire length. 21. A covering according to claim 15, wherein each secondary absorbent element is secured to a top face of a dissipating element, said top face being opposite from a bottom face that is secured to said main absorbent element. 22. A covering according to claim 15, wherein the dissipating elements are more rigid than the absorbent elements and are made of a material.
