A considerable attention is given to materials with the fast ion transport called solid electrolytes because of the possibility of their application in modern electromechanical devices. While many known crystalline materials with the ability of fast ion transport have the limiting factor of their application in the achievement of requested structural parameters ensuring the high ion conductivity, the ion conductive glasses have several advantages the most important of which are: the absence of grain boundaries, the isotropic properties and the composition variability. The acoustical methods have been proved an effective tool to study the fundamental structural and mechanical properties of the ionic materials and can also significantly contribute to find the fundamental experimental knowledge's about the mechanical properties of the new kinds of ion conductive glasses and determine their relationship with the electrical ones. In the present contribution we have illustrated the coherence between the acoustical and electrical properties of ion conductive glasses of the system CuI-Cu_2O-(P_2O_5+M_0O_3). The both acoustic and electrical measurements are also utilised to the study of relaxation processes occurring in these ion conductive glasses and to the ion activation energies determination.
