AbstractIn noisy environment, the speech level and volume of the space were dominant factors for speech intelligibility. However, in a quiet environment, the absorption was more effective than speech level or volume. Decreasing the volume of the classrooms would be the most effective solution. Installing a suspended acoustical ceiling would be an option since they decrease the RT and increase RASTI.
