AbstractDetailed acoustical measurements were made in 41 active elementary school classrooms near Ottawa,Canada to obtain more representative and more accurate indications of the acoustical quality of conditions for speech communication during actual teaching activities. This study found: a mean speech-to-noise ratio in active classrooms of 11dBA, reverberation times from 0.3 to 0.6 s that were not related to noise levels, and the effects of children on acoustical conditions.
