### Abstract

The article concerns the propagation of small-amplitude inviscid and unsteady disturbances on steady nonuniform mean flows. It is shown that, when the behavior of the two-dimensional and compressible mean flow is approximated by the tangent gas relations, the inhomogeneous wave equation can be transformed into a much simpler form involving only one variable coefficient. Further simplifications are possible when the mean flow is a small perturbation of a uniform stream.
