In this paper we compare two time-domain BEM procedures applied to wave propagation analysis in layered media: the first comes from a classical weak formulation of the corresponding boundary integral equations, the second from a new "energetic" weak formulation which has a more robust theoretical background. Some numerical results will be presented, pointing out structural and conditioning properties of the derived linear systems. A numerical analysis of the two approximation procedures stability is carried out, too.
