Good communications is clearly extremely important in a classroom, so high noise levels are not desirable. After (trying to) keep quiet in a classroom for much of the morning, the cafeteria can seem like a good place to release some energy, although not all present will agree. And finally, a gentle reminder to keep voices low in a library can take away the need to verbally remind people where they are.
Mounting a SoundEar Noise Sign in a prominent position in the class room, cafeteria and library will give a clear reminder. The noise level at which the sign lights up can be set accordingly: low sound level for the library, slightly higher for the classroom and a little more forgiving in the cafeteria.
The SoundEar II mounts on the wall on a single screw - see our Installation page for more details. The SoundEar itself is low voltage, taking power from a plug-top adapter to ensure safety.
