The Jeans scale is estimated during the coexistence epoch of quark-gluon andhadron phases in the first-order QCD phase transition. It is shown that,contrary to the previous claims, reduction of the sound speed is so little thatthe phase transition does not affect evolution of cosmological densityfluctuations appreciably.Comment: 9 pages (LaTeX), no figure, revised version of Progress of Theoretical Physics 97 (Letters), 173 (1997
