Enables selection of acceptable noise levels within classrooms, using the traffic light system. As noise level increase, lights change from green to yellow then red with or without sound. Noises become visible for all children.
In addition you find three films with smiley faces included to give an even better illustration to the signals. This enables you to dictate acceptable noise levels in your school.
An adjustable sound level meter controls the decibel level.
Table mount or wall brackets included.
Due to the newly-made battery operation you are independent from cabling. The LED signal lights, with a durability of about 100 000 power-on hours, are ready for use at any place and any time.
Thanks to rechargeable batteries (not included) a continuous operation of 6 hours is possible.
