At low frequencies in small rooms the number of acoustic modes is sparse. In this region the sound field can be most easily modelled using the method of modal decomposition. From this it is possible to extract the transfer behaviour of the room for different source and receiver locations and to analyse the pole-zero positions. In this paper it is demonstrated that the locations of the poles are independent of the source and receiver. The effects of some room correction methods are shown in this context.
