Abstract
The classical wave equation applies to the propagation of sound waves that are (i) linear are of small amplitude, (ii) in the absence of dissipation, (iii) in a steady and homogeneous medium (iv) at rest. The paper proves 60 extensions of the classical wave equation for sound in more general conditions, including: (i) non-linear or large amplitude waves; (ii) dissipation by viscosity and thermal conduction; (iii) media whose properties depend on position (inhomogeneous) and/or time (unsteady); (iv) moving media including potential, compressible, sheared and swirling mean flows.
