Conference_programme: 18.1 - Effect of room acoustics and noise on speech intelligibility and task performance in schools
Lecture: Speech and noise measurements in active university classrooms
Author(s): Choi Youngji
Summary:
One can measure speech and noise levels separately but then the noise is not the same as experienced during the speech in active classrooms. Acoustical measurements and recordings were made during 15 lectures in 11 university classrooms. A statistical method modified by Sato and Bradley (2008, JASA) was used for obtaining octave band speech and noise levels in active classrooms. In the 11 active university classrooms the students experienced: speech levels of 51.5 dBA (s.d.=2.7 dBA), noise levels of 44.3 dBA (s.d.=2.1 dBA), and a speech-to-noise ratio of 7.2 dBA (s.d.=2.7 dBA).
