PRODUCT DETAILS
A self-monitoring traffic light sound meter. The green light stays lit until noise in the classroom goes above the set level (determined by teacher), green light then goes off and flashing yellow light comes on as a warning. When the sound level reaches 15 decibels above the set level, red light and siren sound comes on. The teacher can adjust acceptable levels of noise for quiet activities or louder group work, and also has the option of turning the siren sound off. The 17" H x 5-1/2" wide unit can stand on its own or be wall mounted. Computerized light has a sound level meter that can be set from 50-110 decibels. 120V AC.
