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.
