Comparison of Several Identification Methods of Room Acoustic Impulse Response

In some cases, the infinite impulse response (IIR) models in the identification of room acoustic impulse response do not achieve any significant gain over the finite impulse response (FIR) models. This paper treats adequateness of the several system identification algorithms for the FIR modeling of room acoustic impulse response. The least squares , instrumental variable and prediction-error methods are compared. The influence of the room background noise on the identification process is investigated.
