The Yacker Tracker appears to be a traffic signal, but actually signals too much noise. Select 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 monitoring noise levels in the classroom, childcare, or home. The Green light stays lit until noise in the room goes above a set level (determined by user), the green light is then replaced with a flashing yellow light as a warning. When the sound level reaches 15 dB above the set level, the red light and siren are activated. It can stand on its own or be mounted to the wall and plugs into any standard 120v electrical outlet.
