This study summarises and compares the measurement results of acoustical properties of an auditorium located on the campus of the Faculty of Mechanical Engineering at the Cracow University of Technology. The auditorium was thoroughly modernised and its acoustic features adapted. Measurements of the room acoustics were first taken prior to the modernisation program and were repeated after completion of the modernisation works. Evaluation of auditorium acoustics was based on the following parameters: reverberation time, early/late energy ratio (clarity) C_{50}, early decay time, speech intelligibility indices, and uniformity of sound distribution. The effect of the modernisation program on levels of those parameters are explored and conformity to the design objectives is analysed.
