We report on an experimental observation of classical diffusiondistinguishing between structural universality classes of disordered systems inone dimension. Samples of hyperuniform and short-range disorder were designed,characterized by the statistics of the placement of $\mu$m-thin parallelpermeable barriers, and the time-dependent diffusion coefficient was measuredby NMR methods over three orders of magnitude in time. The relation between thestructural exponent, characterizing disorder universality class, and thedynamical exponent of the diffusion coefficient is experimentally verified. Theexperimentally established relation between structure and transport exemplifiesthe hierarchical nature of structural complexity --- dynamics are mainlydetermined by the universality class, whereas microscopic parameters affect thenon-universal coefficients. These results open the way for non-invasivecharacterization of structural correlations in porous media, complex materials,and biological tissues via a bulk diffusion measurement.
