Abstract

Measurements of RT, EDT, $D_{50}$, $C_{50}$ and STI carried out in three different unoccupied University classrooms. For acoustic measurements, various sound sources are used (white noise, pistol shot, MLS and sweep signal). In this study, It found that interaction exists between sound source and place. Also there was high correlation between STI and various acoustic parameter.
