Classroom noise meter
A classroom noise meter for the projector: it shows how loud the class is and rings a bell over your limit, and it never records sound. It needs a free teacher account.
This is the Sound level from OpenEduCat Board, where it sits next to everything else you use in a lesson.

Does it record the class?

Why does it ask for the microphone?
