Reverberation Time, Classroom, Acoustic SimulationAbstract
Usually, a single value of each acoustic descriptor is adopted for the entire classroom, in order to characterize the reverberation conditions of this environment. In existing schools the use of curtains is a low cost mechanism to try to correct any values by bringing these parameters to acceptable ranges. The present research focused on the spatial distribution of the parameter reverberation time in classrooms with open and closed curtains. The tool used to estimate the sound behavior was computational simulation using the software Odeon. The classroom models were adjusted using reverberation times measured in the real rooms. For the classrooms, two configurations of closed windows were studied: open and closed curtains. The impact of using the curtains on the value of the reverberation time varies according to the frequency. Its use does not significantly improve the homogeneity of the reverberation time distribution in this environment.
