We examine the effect of quantum fluctuations in a tunable cold Fermi gas on phonon propagation. We show that these fluctuations can be interpreted as inducing a stochastic space-time. This effect can be displayed in the variation in the travel time of phonons, at its greatest in the crossover region between Bose-Einstein condensate and BCS regimes.
