Encourage better behaviour within the classroom with this effective traffic light design noise level monitor. With variable settings, the Chatter Tracker will let children know when they have exceeded an acceptable volume and can be set to respond to levels ranging from 50dB (a whisper) to 110dB (a rock concert).
Warnings can be given by the traffic light system, a siren, or an announcement – includes the pre-recorded message “Quiet Please” in English, Spanish, French and German. There is also an option to record your own 15 second message. A resettable digital counter records how many times the noise level has been exceeded.
Mains or battery powered for portability – requires 6 AA batteries.
