      abstract     = {In this work, a highly scalable numerical method is
                      presented that allows to compute the aerodynamic sound from
                      the flow field for large-scale problems. The acoustic
                      perturbation equations are solved by a high-order
                      discontinuous Galerkin method and by using the acoustic
                      source terms obtained from an approximate solution of the
                      Navier-Stokes equations. Both solvers operate on the same
                      hierarchical Cartesian grid. This direct-hybrid method is
                      validated by monopole and pressure pulse simulations and is
                      used to compute the aeroacoustics of a turbulent mixing
                      layer. The results indicate that the new method is capable
                      of efficiently predicting the acoustic field and show that
                      it is suitable for highly parallel simulations.},
