Classroom Noise Meters
Simple Noise Meters You Can Use in Your Classroom
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 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.
