Abstract:	In this paper, a novel procedure for the estimation of the energy decay curve of the reverberation on rectangular non-diffusive rooms is presented. It is based on the calculation of the expected sound intensity using a room characteristic factor, the specific attenuation factor, also introduced in the paper. Complete knowledge of the probability density function of this factor leads to exact estimation of the energy decay curve of reverberation, even in the case of heavily irregular rooms and/or un-homogeneous walls.
