Three Tools to Help Students Understand Classroom Noise

I like the sound of a classroom full of kids talking and working together on projects. But there are times when students need to be aware of the volume of their voices during those times that they're working together. And there times when you do need your students to be quiet for activities like silent reading or journal writing. You could play the role of judge and jury when it comes to classroom noise or you can get some help in the form of a simple noise meter that you display on a screen in your room. Here are three simple noise meters that you can use on your laptop and display on a screen in your classroom.

Bouncy Balls is a free online noise meter that I have been using for a couple of years. It shows the volume of the noise in a room 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.

Zero Noise Classroom is a countdown timer and a noise meter into one convenient Chrome app. When you launch Zero Noise Classroom you can set the countdown timer and adjust the goal for the volume of noise in your classroom. You will also set a goal for a percentage of the time that can exceed the maximum volume. When the countdown timer expires a chime sounds and the percentage of time above the volume limit is displayed.
