Zero Noise Classroom: Noise Level Display and Stopwatch

Zero Noise Classroom is a useful tool: a free Chrome extension, developed to help manage noise levels in classrooms. It is effectively employed during cooperative learning activities, as it makes students aware of the noise level in the room and encourages them to self-moderate. When an activity ends, the tool displays the percentage of time the noise level surpassed the optimal level, enabling teachers to implement gamification tactics for better learning. Additional features include adjustable microphone sensitivity and real-time stopwatch. The extension has been continuously improved through regular updates, each intending to enhance user experience, with the latest featuring an updated app icon.

Extension summary

The free noise level display and stopwatch for the cooperative classroom.

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.

The app doen't work in de latest version of Chrome. Is there an update comping up?
by Hilleke Steenveld, 2023-10-09

Es bueno que cuando vaya terminando la cuenta regresiva tenga un aviso sonoro de que se está por terminar el tiempo, pero este sonido es tan ruidoso que no sé si hasta aumenta el porcentaje de ruido. Eso me decepcionó. El sonido que eligieron como indicación de que se está por terminar el tiempo es completamente incompatible con el objetivo de la clase: tratar de controlar el ruido innecesario.
