Claim 0:
1. A sound insulation element,
that utilizes a strong force-network as a principle energy dissipating mechanism, wherein
the strong force-network is generated through complex interactions of solid particles in a granular system, which leads to periodic formation of maximal number of interconnecting pairs-of-forces according to 3rd Newton's Law,
wherein said strong force-network is realized by using a granular material made from at least one solid material with a specific skewed multimodal particles-size-distribution, comprising
a granular material comprising particles, and
a supporting structure having at least one cavity, whereat the at least one cavity is filled with particles of the granular material, characterized in that
a distribution assigning a number (N) of particles to an equivalent outer diameter (D) of the particles is selected such that the particles form an energy dissipating strong force-network within the at least one cavity,
wherein the distribution assigning a number (N) of particles to an equivalent outer diameter (D) of the particles is an asymmetric distribution,
wherein the distribution of equivalent outer diameters (D) of the particles is multimodal, and
wherein said multimodal distribution is skewed, such that said multimodal distribution has one maximum mode (i) having a maximum number (Ni) of particles assigned to a fundamental equivalent outer diameter (Di) of particles, and
wherein said maximum mode (i) has at least one preceding mode (i−1) and at least one subsequent mode (i+1).
