The formalism of a prevision model of sound levels into empty and cluttered up rooms is presented here. This model uses the hypothesis of diffuse reflection at the wall and is based on the hypothesis that congestion is made up of obstacles wich can be considered as particles relative to the dimension of the room. The comparisons between calculated results and mesured results are satisfactory with consideration on the dubiousness of the parameters' values wich characterise the behaviour of the congestion.
