A finite element model for calculating acoustic transmission function and acoustic impulse response in rigid rooms has been presented in this paper. It was shown that the computer model successfully predicts the effects of different source_receiver locations on sound pressure level amplitude spectrum and the temporal structure of impulse response. As an example, a rectangular room has been modeled with details.
