Compra PRO noise traffic light

With the Noise Traffic Light Pro, you can easily monitor the noise level in the classroom. Recognizable symbols—red, yellow, and green—illustrate the current noise level in the environment. With the help of the four adjustable noise levels, you can regulate the acceptable volume. If the class gets too loud, the traffic light automatically switches to yellow or red. An audible signal can be activated, which sounds when it turns red. This makes noise visible to all students. The battery operation frees you from annoying wiring. The Noise Traffic Light is always ready for use, anywhere. With batteries (sold separately), it can operate continuously for four to six hours. The LED lights have an average lifespan of about 100,000 operating hours. With the four strong magnets (sold separately), you can easily attach the Noise Traffic Light to any metal surface.

To keep the volume low in the classroom and ensure a quiet environment, the Noise Traffic Light Pro is the perfect solution for teachers. It is also a straightforward and practical solution for use in libraries, quiet work zones, and break rooms, helping to create a pleasant working atmosphere.
