It helps students be aware of the noise level in the classroom during cooperative learning activities, and moderate it accordingly.

When time is over, the percentage of time that the noise level has exceeded the optimal level is displayed, so the teacher can use that value in gamification techniques.

Adjust the microphone sensibility in your operative system for best results.

Code partially adapted from https://github.com/cwilso/volume-meter by Cris Wilson.

Uses free Saxmono and Roboto fonts, IcoMoon scalable icons and sound from http://soundbible.com.

Special thanks to Julio Lozano for testing.
