AB  - In a previous paper [1], it was shown that the influence of neglecting the incidence-angle dependence of absorption coefficients in a single-source, shoebox room model was insignificant as far as simulation results are concerned. Neglecting phase shift at each reflection led, however, to a significant difference in the predicted pressure level in the same model. This paper investigates the same two questions in a complicated model with several sources and a diversity of surface materials. It attempts to analytically estimate the error associated with the disregard of these two issues.
