"The Gab-Stopper is an audio monitoring and feedback
tool designed to help children (grades K-12) function quietly
in the classroom. Using brightly colored graphics, Gab-Stopper
provides easy feedback in the form of a standard traffic light.
Green indicates acceptable voice levels; yellow means warning
and indicates increasing voice levels; red means alert and
indicates sound levels are unacceptable. Optional warning
and alert sounds can be played on the computer to remind young
ones to settle down. As an incentive, Gab-Stopper provides
an automatic score indicator ranging from 0 to 100. If voice
levels are kept low, the score increases. If voice levels
rise, the score decreases."
