On the basis of Nariai's new formalism for dealing with the generation of sound from primordial cosmic turbulence, the intensity of sound (at the center of an expanding turbulent fluid sphere within the acoustic event horizon) and the ratio of sound energy to that of turbulence are numerically calculated for several values of n (a parameter specifying the decay law of cosmic turbulence) and M_i (an initial Mach number). It is shown that, contrary to Jones's assertion, the acoustic decay of primordial cosmic turbulence is negligible irrespective of a concrete form of the spectral function. It is also shown that a more reliable fixation of n is necessary to make clearer the formation of galaxies from cosmic turbulence.
