Expressions for a damping factor and an acoustic wave velocity in a porous reservoir are obtained by acoustic emission method in case of the harmonic excitation. The solution is obtained assuming that the pore sizes are small in comparison with the distance at which motion and response char- acteristics of the movement changes significantly. This allows us to suppose that both media are continuous there will be two vector distances at each point of space that are elastic component vector distance and interporous medium one. A comparative frequency functional connection of the relative acoustic wave velocity in a porous reservoir are graphed in case of a positive and negative Poisson’s constant. Results of work may be used when revealing informative signal shapes of the acoustic emission in two-component porous media.
