An isothermal jet with a Mach number of M = 0.9 and a high Reynolds number of ReD = 4 x 10^5 is computed by LES. Both the flow field and the sound field obtained directly from the unsteady compressible simulation are found to be in good agreement with the corresponding measurements of the literature. In particular, the acoustic field shows spectral and two-point properties, as a function of the observation angle, which are characteristic of such a high Reynolds number jet.
