title: An approach to numerical quantification of room shape and its function in diffuse sound field model.
abstract: This paper deals with an approach to the numerical quantification of room shape and its possible role in diffuse field modeling. The normalized shape factor of the room is introduced as a function of the room volume and the room interior surface. It was shown that in real rooms the value of normalized shape factor ranges from about 0.57 to 0.9. Some simple transformations of well-known formulas by introducing the room shape factor are also discussed. Such approach seems appropriate in architectural acoustics courses as a straightforward way to explain the factors influencing the acoustic response in a room.
