Analytical Solution of Sound Wave Propagation in Moving Medium (1D Problem)

I am assuming a simple problem with the following assumptions: Fluid flow is one-dimensional. Fluid motion is uniform. … Sound source is a point-source (i.e., sound source does not affect fluid flow). I am looking for 1D solution that can estimate acousic wave amplitude as function of space ($x$) and time ($t$). …
