Abstract
The whole proceeding of the evaluation of turbulent jet noise with Lighthill formulation from large scale instationnary aerodynamic data is presented. The basic case of the two-dimensional shear layer is completely studied and the main features of the method are established. The far field acoustic fluctuations show a satisfying spectral contents and the directivity can be compared to what is observed for subsonic jets. The first aerodynamic data of the plane jet are also presented. They should allow more precise acoustic validations before the more realistic case of the axisymmetrical jet.
