    A high-order implementation of the Discontinuous Galerkin (DG) method was presented for solving the three-dimensional Linearized Euler Equations on an unstructured hexahedral grid. The method was based on a quadrature free implementation and the high-order accuracy was obtained by employing higher-degree polynomials as basis functions. Non-reflecting boundary conditions were implemented at the boundaries of the computational domain. The results obtained show that the hexahedral elements were more accurate than the results obtained on tetrahedral elements. The results were compared to the leading term in a series expansion of the analytical solution.
