  Two component superlattice film of 2N layers is considered and dimensionally
quantised spectrum of phonon-s is found. The problem of localization of
phonon-s in the superlattice with random thicknesses of the layers is
investigated. The Landauer resistance of the transport of phonon-s is
calculated exactly. For short range disorder the numerical analyses shows, that
at frequency \omega=0, there is delocalized state and the correlation length
index \nu is equal to 2.
