Abstract

Acoustic comfort has a huge impact on teachers’ health and students’ productivity. A good acoustic environment can change the child’s perception of the teacher. To obtain a good acoustic environment for a school classroom, the background noise and the reverberation time should be as low as possible. Thus, the aim of this investigation is to determine the reverberation time before and after applying sound absorbing materials in a classroom situated in a college from Bucharest. Further on, the measurements were compared with the results obtained from the reverberation time formulas. The speech transmission index was determined based on the reverberation time to highlight how the occupants perceive the classroom from the acoustical point of view. Important issues were discovered in obtaining the optimal reverberation time in schools.
