Evaluation of the Reverberation Time as an Objective Parameter of the Acoustical Quality

In this work reverberation time as one objective parameter of acoustic quality of a room is analyzed, as well as their optimal values related to role the room and correlation with subjective perception. Based on measurements in two architecturally identical, but according to acoustic characteristic two different rooms, and additional analysis and calculations connected with number of people in a hall, reverberation time are evaluated according to earlier adopted optimal conditions involving certain deviations from the optimum values.
