Loud, Acceptable, Quiet Green - yellow - red - noise becomes visible here!
... These noise traffic lights make sure that kids in a group can learn with all their concentration. As in the case of three-stage traffic lights, they control the "noise traffic" in the room. Familiar traffic-light colours indicate the noise level. If its too high, the traffic lights turn red. The acceptable intensity of noise can be adjusted by means of 4 levels. Its also possible to select the individual lights manually. If required, the red light can even be supported by a signal tone, whose volume is infinitely variable. No matter if they are put up on the table or hung up on the wall - the noise traffic lights remain in every childs field of view. The LED lamps have an average working life of 100,000 operating hours. Usable by power supply via a power cable. You could use it also portable via the Battery/accu pack (available seperately: 110-369 Battery/accu pack for Noise-Signal-Light). This battery pack is rechargable directly through the Noise-Signal-Light if you plug in the power cable of the Noise-Signal-Light into the plug socket.
