The paper discusses methods of modeling the acoustic transfer functions for systems of active noise cancellation. For the purpose of this study we considered rooms with arbitrary shape. Based on a priori information about the managed object we proposed a new approach to modeling. Our work shows the high efficiency of tracer methods in modeling the transfer functions in the rooms of any shape. Finally, we assessed the conformity of the proposed models for various input types.
