Bouncy Balls. Visualize the sound level of your class

Last updated on 12 February 2025

Bouncy Balls is amazing little tool that allows to visualise the sound level of your location using your computer's built-in microphone.

Back to school also means rediscovering the perpetual background noise that drives your class on a daily basis. This more or less loud, more or less permanent hubbub, which is especially good when it stops 😉

Bouncy Balls will help you visualize it and why not show it to your students so that they become aware of it and try to control it.

This online application is very simple to understand. Going to the front page of the site, you will see a beautiful image composed of dozens of small bubbles of all colors. Click on "Begin Bouncing". The balls will fall at the bottom of the screen and you will have access to a small menu on the right. You will see a scratched microphone. By clicking on it, you will activate your computer's microphone.

As if by magic your colored balls will start to move and trip depending on the sounds picked up by the microphone. The more the background noise will be, the more the balls will have the moveotte. All you have to do is project the image to your students and challenge them to master the movement of the balls.

With this small menu on the side of the screen, Bouncy Balls allows you to choose the number of balls displayed on the screen. You can also choose to display something other than bullets. Emojis should appeal to your students.

Well if it doesn't work you still have the opportunity to go back to the good old traditional methods … pschhiiiit … less fort …. pschhiiit …. silence …. 🙂

Bouncy Ball is free and ad-free.
