Resumen: The simplest room acoustics formulas are valid in a diffuse sound field. How is a diffuse sound field defined? Which is the scope of these formulas? These questions are analyzed through more general theories, in turn explained with figures instead of formulas with the intention to approachquickly to the concepts. The scope of the diffuse field model is analyzed and simple tools are presented to address the cases in which it would not be adequate assuming diffuse field. The wave theory model and the ray model are presented in a simple format with visual support and a succinct reference to the underlying mathematical models. A discussion about the current criteria to define a diffuse sound field in the frequency domain as well as in the time domain is proposed.
