Influence of not homogeneous absorption on reverberation time

In present days, the indoor spaces need more and more attention on the design of acoustic proprieties of enclosed environments such as conference rooms, classrooms and offices. In order to obtain low internal noise levels and correct speech intelligibility, indoor sound field should be studied properly.In this work, a comparison of the reverberation time measured and calculated in two rooms using different model has been made. Results clearly show that calculated results are not in agreement and differ from measured values.
