heal.abstract	Rooms are modeled as linear time invariant systems, where the acoustic transmission characteristics between a specific source receiver pair are described by the room impulse response. (RIR). A recursive realization of the short time Fourier transform is employed to decompose the RIR in the time frequency domain, where the different subband signals are approximated by parametric models. The pole-zero models, evaluated by the Steiglitz-McBride iteration, perform perfect reconstruction of the early reflections, whereas the decay rate of the reverberant part is sufficiently approximated. The RIR of a real room is studied as an example case.	en
