Summary

Chapter 6 introduces the three-dimensional analytic theory of sound propagation in ducts and presents acoustic models of hard-walled and lined uniform ducts. Also discussed are the effects of gradual cross-section non-uniformity, circular curvature of the duct axis, and sheared and vortical mean flows.
