ABSTRACT
The paper presents the results of measurements and theoretical calculations for little room models. Five room models have been prepared for analysis and they were placed in a chamber adopted as reverberationless. Measurements of reverberation time in these rooms were made in two variants; first in isotropic sound field, the second in the field disturbed by elements made of mineral wool. Then for all models in both variants theoretical calculations were made by means of three models: Neubeauer’s, Sabine’s, Eyring’s. All the results have been analysed by means of STATISTICA software and based on
them statistical inference of theoretical models was made against the measurements for little box rooms.
