AB  - Many ray tracing algorithms make use of the single-valued diffuse-field absorption coefficient to simulate the sound field in a given room computer model. They consider, however, neither the effect of the angle of incidence nor the fact that the reflection factor is complex. If characteristic impedance and wave number, which are measured in an impedance tube, are known, we can expect reflectograms, which look different from those generated by current simulators, and look different for different thickness. The paper investigates how far the angle-dependent reflectograms, which consider phase shift due to complex reflection factors, look different from the angle-independent ones, and whether the statistical nature of reflectograms leads to the cancellation of such effects.
