Study of the reverberant field in a room

Given the number and complexity of the laws governing the radiation, propagation and behavior of waves in the presence of obstacles, it is currently impossible to accurately determine the evolution of the acoustic field inside a room.

Moreover, the search for quality criteria for a room leads to a wide variety of physical parameters that can be taken into account in the very definition of quality.

In practice, users want to characterize a room based on a minimum number of dimensions, but this tendency to want to "quantify" the room is hardly conceivable within the strict framework of the geometric approach.

Any overall assessment of the intrinsic quality of a premises requires a statistical formulation.
