| Abstract: | We show results obtained by Biot's equations and a simple Theory of Porous Media-based hybrid model describing acoustical waves in a gas-saturated high-porous foam. The resulting dispersion relations for the longitudinal mode and phase velocities vs. porosity show the extraordinary effect of waves in gas-saturated porous media.
