A simple asymptotic inversion method for obtaining an estimate of the difference in internal sound speed from differences between 5 min p-mode oscillation frequencies is presented. Thus, given a known model and a set of frequencies of a model of unknown structure, or of the Sun, the internal sound speed of the latter can be estimated. Numerical experiments with error-free frequencies indicate that this method can provide an estimate of the sound speed, from the energy-generating core to the helium ionization zone, with smaller fractional error than any published results. The method was applied to real solar data, showing that the solar sound speed is indeed broadly as determined by an earlier investigation at those depths for which the earlier inversion should be reliable.
