The space and time discretization inherent to all FDTD schemes introduce non-physical dispersion errors, i.e. deviations of the speed of sound from the theoretical value predicted by the governing Euler differential equations. A general method-ology for computing this dispersion error via straightfor-ward numerical simulations of the FDTD schemes is pre-sented. The method is shown to provide remarkable ac-curacies of the order of 1/1000 in a wide variety of two-dimensional finite difference schemes. 1
