The initial observation is that rooms are sounding objects and, in particular, wave propagation as it is found in rooms is representative of what happens for a large variety of other sounding objects.
The BaBo can be thought of as a generalized model of resonator, belonging to the exciter-resonator classical view of physical modeling. It keeps the main advantage of physical modeling techniques, that is the availability of physically meaningful parameters like size, absorption, damping, diffusion, etc. . At the same time, the BaBo model is sufficiently general to be used as instrument resonator, post-processing filter, or reverberator.
For a thorough description of the BaBo, refer to the article in the Computer Music Journal, vol. 19, n. 4, 1995.
