Research report from Enginyeria La Salle, Universitat Ramon Llull, Barcelona, Spain, 2002
This paper shows the results of a preliminary part of a study about the behaviour of
reverberation time equations. We have focused our work on the non-uniformly absorption
distribution case, because this situation is not studied by classical formulations.
The first part of the paper includes a theoretical introduction about equations for predicting
reverberation time from Sabine’s formula to some of the newer ones.
The second part shows some results from measurements, simulations and analytical
calculations for a real case.
