Abstract : This paper gives an overview of some important features of the process of sound generation in subsonic jets. The outstanding aeroacoustic theories are briefly reviewed and some distinguished phenomena relevant to jet noise, like both the effects of source convection and temperature are explained. Finally some mechanisms of sound generation by turbulent jets reported in the literature on the topic are examined.
