Sound propagating in a moving medium is governed by a so-called convected wave equation. Consider the case where the background flow velocity is uniform in the x-direction with velocity V .

a. Following the procedure in Sect. 2.1, derive the convected wave equation for sound in a one-dimensional environment with flow velocity V:
