Chatter Tracker enables you to dictate acceptable noise levels within classrooms using a recognisable traffic light system.

As noise levels increase (levels set by you), lights change from green (acceptable) to amber (noise level increasing), then to red (too noisy -with or without siren).

Mains or battery powered – can be wall mounted with the bracket provided if desired.

You can also record your own message/announcement of up to 15 secs and there is a pre-recorded “quiet please” message in English, French, German or Spanish.
