    Abstract

    In this paper, the acoustical wave propagator scheme is implemented in Fortran for predicting sound propagation in a one-dimensional duct. Example calculations are performed for a semi-infinite duct and a duct with a solid blockage. Numerical accuracy of our results is examined and compared with the finite-difference time-domain method. This scheme is found to be highly accurate and computationally effective for describing the time-domain evolution of acoustic waves. Multiple reflections within the solid blockage and phase changes of the transmitting wave from solid back into air are illustrated through the implementation of this scheme.
