The SoundEar Noise Activated Sign presents a clear and unmistakable warning as soon as the noise exceeds the preset limit. Children and adults can easily understand the warning symbol so that immediate action can be taken. It mounts on the wall and plugs into the mains power with the adapter that is included.
This sign was designed in Scandinavia to look at home on the wall of any office, school classroom or factory.
The noise limit is selectable to suit the function of the room. It can be set in 5 dB steps to a level between 40 and 115 dB(A) using the control on the back. These settings represent the noise levels between a classroom and a rock concert.
The yellow lights come on just before the limit it reached. As soon as the limit is exceeded the red part lights up and the word WARNING is displayed.
