This paper proposes the application of the Lattice-Boltzmann method (LBM) for the characterization of the acoustical impedance and sound radiation properties of wind instruments. The validation of the method is achieved by simulating the radiation of an open unflanged pipe with LBM andcomparing the impedance related data and radiation results with those obtained through the exact solution derived by Levine and Schwinger for the same model.
