Summary

This review discusses much recent progress in understanding both the physical mechanisms and the mathematical description of the acoustical features of unstable flows. Attention is focussed on the receptivity problem for forced shear layers and the radiation fields accompanying the launching of an instability wave; on the evidence for significent direct radiation from the instability in both subsonic and supersonic jet flows; and on the role played by instabilities in aeroacoustic analogy theories. A number of important outstanding problems are identified.
