Do sound enhancement systems work in an open classroom?
Yes. Enhancement of the speech signal is highly desirable since the speech-to-noise ratios are often poorer than closed classrooms, for two reasons: The background noise levels are predictably higher, and the teachers often use softer than average voice levels in order to reduce interference with the teachers in adjacent classrooms. However, it is more challenging in that placement of the speakers is critical and teachers may need to coordinate schedules and alternate use of the system to avoid interference. If the volume is properly set and regulated, it is feasible.
