A novel method for modeling frequency-dependent boundaries in finite-difference time-domain (FDTD) room acoustic simulations offers a significant improvement over the conventional one-dimensional approach. The method incorporates a digital impedance filter resulting in multidimensional formulation. Reflecting sound waves approximate the theoretical reflectance for any value of wall impedance and angle of incidence, especially at low frequencies. Both phase and amplitude are preserved. Results obtained from numerical experiments confirm the validity of the approach.
