As it is still new, no previous study has been done to understand the relation between space dimensions, building material, and surroundings to this school classroom acoustic quality. Therefore, this journal studied

... ic quality by calculating Reverberation Time (RT60) and measuring Background noise value of one typical class of Sekolah Alam in Bandung. Reverberation Time (RT60) was calculated using space dimensions and materials that exist within the studied classroom, while the background noise value was measured using Data Logging Sound Level Meter (SLM). The results indicate that the studied class has an ideal acoustic quality for learning activity. The main factors that affected these results are the classroom has a small size in volume and surrounded by lush trees which work as noise controls.
