A weak solution of the coupled, acoustic-elastic, wave propagation problem for a flexible porous material is proposed for a 3-D continuum. Symmetry in the matrix equations; with respect to both volume, i.e. 'porous frame'-'pore fluid', and surface, i.e. 'porous frame/pore fluid'-'non-porous media',
