What is this about?
A classroom noise meter helps pupils notice the sound level of the room before it becomes disruptive. Instead of stopping an activity again and again, the teacher can agree on a suitable noise level and let the visual display support that agreement. This topic page leads to the CalmClass noise traffic light, a simple browser-based tool for smartboards, laptops and tablets. It is especially useful during partner work, group tasks, quiet writing phases or stations. The point is not surveillance; it is shared orientation. When pupils see the display change, they can regulate their own volume more easily. A short reflection after the activity makes the tool stronger: Was the level right for this task? What helped the group stay focused? In that way, the noise meter becomes part of classroom management rather than a punishment signal.
Classroom use
- Show a shared noise target during group work
- Support quiet independent practice
- Use the smartboard as a calm visual reminder
