Abstract : We describe a numerical scheme for hyperbolics well adapted to both aerodynamics and aeroacoustics. The scheme is vertex centered, It applies with second order accuracy to unstructured tetrahedrizations and extends to higher order (up to sixth) on a certain type of cartesian meshes. Several basic aeroacoustic numerical experiments are presented.
