%X Assessing the quality of room acoustic is eventually always subjective. The only question is how strict are the criteria which should be met, what is the purpose of space and how important is the quality of listening for the listeners. Subjective tests were made for 18 room acoustic quality parameters of two multimedia classrooms with various acoustics treatment. Tests were conducted with 45 healthy examinees aged 20-25 years. Tests were carried out in two ways, with and without the influence of listening memory, and in two acoustically differently treated multimedia classrooms. Statistical analysis of the results was made, and the impact of listening memory to the obtained results was observed. In addition to subjective tests, objective measurements of both classrooms were made, and compared together. Objective measurements were done in accordance with ISO3352. Reproducing system was calibrated, and it was identical in both classrooms.
