The simultaneous collision of a specially arranged layers in vacuum, as in the similar case for the media compressed by the train of shocks generated during multi-staged instant accelerations of a piston with result in the peculiar reverberation of shocks, is describable by the nonisentropic analogue of the Riemann invariants B(-)= u - 2D/[ Cp/Cv - 1 ] = u -fD and B(+)= u + 2D/[ Cp/Cv - 1 ] = u +fD - strictly rigourously (with the local shock velocity D instead the sound velocity a ). The real equation of state (EOS) effect consists, for the fundamental instance, in the variation of Cp/Cv, as during photon number density increase, i.e. in evolution f = 3->6. Another like effect consists in variety of EOS for the different materials, as it follows from our joint theoretical research with Dr. M.Basko and Dr. N.Barysheva. The asymptotics of the reverberation corresponds to the limit D->a, with more abstract limit of the infinite frequency of reverberating acoustical waves. The effective generation of gravitation waves by the supercompressed media is then possible, in the principle.
