Chatter Tracker Classroom Sound Monitor

Yacker Tracker classroom sound monitor
The Yacker Tracker appears to be a traffic signal, but actually signals too much noise. Selent the appropriate sound level for any given situation and let the Yacker Tracker be an audio-visual reminder when the noise level gets too high. Perfect for K-12 classroom teachers to use with their students.

How it works.
The green light stays lit when the noise level is below a setting you specify. But when the noise goes above the set level, a flashing yellow light comes on as a warning. When the sound level reaches 15 decibels above that set level, the red light and a siren come on. The siren feature can also be turned off. Decibel level may be set from 50 to 110. Acceptable levels of noise can be adjusted for quiet activities or louder for group work.

Other Uses
Nursery schools with hearing impaired students can use the unit as a visual signal
Speech pathologists teaching voice projection
Hospitals, monitor hallways, and waiting rooms
Drama departments which need to monitor noise levels backstage
Great for libraries, town halls, and polling places
