• Resumen

  • Sabine and Eyring equations are based on the diffuse field theory. However, most cases in real rooms present a non-diffuse sound field. This paper addresses an analytical comparison of classical equations to �non-diffuse field� equations, such as Fitzroy's, Arau's or the European Standard EN 12354 part 6 from Nilsson's theory. I out study the influence of the room shape and the absorption distribution in the room are considered. Also scattering effect is taken into account in some cases. According to these considerations, Arau's and Nilsson's model accuracy seems to supersede one to the other depending on the room shape and absorption distribution.
