The flow and acoustic fields that are generated by two coaxial jets are considered. The problem is handled by solving the flow field using Large Eddy Simulation (LES) and the acoustics by a wave equation with source terms provided by the instantaneous LES. The paper is focused on the influence of the grid resolution on the solution accuracy.
