摘要： The invention concerns a sound insulation element (10), that utilizes a strong force-network as a principle energy dissipating mechanism, whereat the strong force-network is generated through complex interactions of solid particles (14) in a granular system, which leads to formation of maximal number of interconnecting pairs-of-forces according to 3 rd Newton's Law, whereat said strong force-network is realized by using a granular material (12) made from at least one solid material with a specific skewed multimodal particles-size-distribution, comprising a granular material (12) consisting of particles (14), and a supporting structure (40) having at least one cavity (42), whereat the at least one cavity (42) is filled with particles (14) of the granular material (12). A distribution assigning a number (N) of particles (14) to an equivalent outer diameter (D) of the particles (14) is selected such that the particles (14) form an energy dissipating strong force-network within the at least one cavity (42), wherein the distribution assigning a number (N) of particles (14) to an equivalent outer diameter (D) of the particles (14) is an asymmetric distribution, wherein the distribution of equivalent outer diameters (D) of the particles (14) is multimodal, having several modes, and wherein said multimodal distribution is skewed, such that said multimodal distribution has one maximum mode (i) having a maximum number (N,) of particles (14) assigned to a fundamental equivalent outer diameter (D,) of particles (14), and wherein said multimodal distribution has at least one preceding mode (i-1) and at least one subsequent mode (i+1).
