Product #: CTU3030YACKER TRACKER  |
A great self-monitoring traffic light sound meter! This unique 17 1/8" traffic light is perfect for teachers to monitor noise levels in the classroom. The Yacker Tracker looks like a genuine stoplight and can stand on its own or be wall mounted; it's computerized with an adjustable sound level meter (effective from 40 dB to 120dB). The teacher sets the sound level and the green light stays lit until noise in the room goes beyond the set level, then the green light goes off and the light flashes yellow. When the noise level reaches 20 dB above set level the red light and siren sound come on. The user has the option of turning the siren sound off, which also makes this a great visual aid for hearing impaired students. Drama departments can incorporate this unit as a quiet signal to alert backstage cast members of inappropriate off stage noise. Intended for adult use in K-12 grades.
