  Acoustic perturbations in an expanding hadronic fluid at temperatures below
the chiral transition point represent massless pions propagating in curved
spacetime geometry. In comoving coordinates the corresponding analog metric
tensor describes a hyperbolic FRW spacetime. We study the analog cosmological
particle creation of pions below the critical point of the chiral phase
transition. We compare the cosmological creation spectrum with the spectrum of
analog Hawking radiation at the analog trapping horizon.
