A number of objective ana subjective acoustical parameters, referring to the reverberance, and spatial distribution of sound and speech intelligibility, were measured before and after the acoustical adaptation of a classroom. Three configurations of arrangements differing in used materials' sound absorbing coefficient were analyzed. The results indicate the expected improvement of the acoustical environment according to design assumptions.
