Two Ways to Visually Show Classroom Noise

Bouncy Balls is a free online noise meter that shows students the volume of the noise in your classroom. Bouncy Balls does this by displaying a set of colorful bouncing balls on your screen. The louder your students are, the higher and more frequently the balls on the screen bounce. To use Bouncy Balls simply go to the website, click "begin bouncing," and then click the microphone icon to allow the site to access your computer's microphone.

Calmness Counter is similar to Bouncy Balls. The difference is that Calmness Counter displays a dial meter to display the decibel level in your classroom. You can adjust the microphone input sensitivity directly on the Calmness Counter screen.

Applications for Education
Projecting either of these meters for all of your students to see could be a good way to help them understand the appropriate volume for conversations while working on group activities in your classroom.
