In this paper, a method of simultaneous analysis of waves propagating through multilayered media consisting of gas and solid fields using the boundary element method is proposed. Usually the waves propagating in gas fields are analyzed using the Helmholz wave equation, where the unknown functions of sound pressures are taken to be scalars. Then, the sound pressures obtained as the result of the analysis of the gas field are imposed on to the solid fields as external forces and the waves propagating in the solid are been analyzed, taking the unknown functions of particle velocities to be vectors. That is, the waves propagating in gas and solid fields are analyzed separately. Naturally, it is considered to be more effective to analyze the waves propagating in gas and solid fields simultaneously than to analyze them separately. In this work, a method of simultaneous analysis of waves propagating through multilayered media using the boundary element method has been developed, using the same equation of motion for gas and solid and considering the same unknown functions of particle velocities as vectors. Also several conditions under which the solutions obtained by the proposed method converge numerically, have been clarified through numerical evaluations.
