ABSTRACT
The use of geometrical acoustics in an inhomogeneous moving medium enables the identification of ray paths along which energy propagates and may assist with the visualization of sound propagation. The basic ideas of geometrical acoustics in a moving medium coincide with those for a motionless medium. Nevertheless, the particular results in a moving medium cannot be obtained from the analogous results for a motionless medium. The main results of geometrical acoustics in an inhomogeneous moving medium were obtained before the mid-1940s. In this chapter, these results and those obtained after the 1940s are systematically derived and presented.
