Classroom Noise Meters

Simple Noise Meters You Can Use in Your Classroom

There is nothing quite like the sound of a classroom full of kids collaborating and working together. But there are times when students need to be aware of the volume of their voices during those times they're working together. There are also times when you do need your students to be quiet for activities like silent reading, journal writing, or test taking.

Bouncy Balls

Bouncy Balls is a free online noise meter that 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.

Zero Noise Classroom

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 spent above the volume limit is displayed.

Calmness Counter

Calmness Counter displays a dial meter to display the decibel level in your classroom. The arrow starts off in green, but moves to yellow and then red when the noise is too loud. You can adjust the microphone input sensitivity directly on the Calmness Counter screen.
