Description:	Four-pole matrix approach is a very convenient concept in modeling acoustic systems, its application has been limited mainly to systems composed of only one-dimensional (1-D) or lumped parameter elements due to the difficulty in formulating four poles of three dimensional (3-D) cavities. In this work, an experimental procedure is developed to obtain four poles of 3-D cavities. The procedure is validated by comparing the four poles obtained experimentally for a rigid-walled rectangular cavity with the four poles obtained by analytical and numerical procedures. Establishing an experimental procedure for four pole formulation is significant as it enables application of the four pole approach to virtually any acoustic systems. The concept of hybrid modeling, which is building the system model by combining experimental, numerical and analytical models, is demonstrated through a simple example as the best application of the four pole approach.
