The article considers the questions of assessment of reverberation processes in rooms with various character of a sound reflection from the enclosures. An efficient technique for calculating of the reverberation sound energy in the rooms with mirror-diffuse reflection of sound is offered. The technique is based on the representation of mirror reflected sound rays in the form of separate groups with parameters corresponding oblique, axial and tangential rays. The article includes the comparison of the calculation of reverberation time results on the basis of the division of all the rays into groups with the results of direct reverberation modeling by tracing rays. A good convergence of the results was obtained.
