How it works

Connect a microphone to measure the Sound Level in your classroom. Use the slider below 'Max. noise' to determine how much sound is allowed and the red-colored bar adjusts accordingly to indicate the limit.


If students make too much noise, you can set a bell to ring notifying them to be quieter. If the noise continues consistently for 10 more seconds, you will hear the bell again. This functionality can be disabled by pressing the bell button on the widget.


If you want to turn off the microphone, press the microphone icon on the widget.

Widget settings

Microphone sensitivity

You can set the sensitivity for your microphone via the widget settings, this setting is automatically saved for users with a Basic and Pro account.

Select microphone

If you have multiple microphones, you can select the microphone you want to use for this widget.

Show counter

By default, a counter displays the number of times the set Sound Limit has been reached if classroom noise persists after 10 seconds. This feature can be disabled in the widget settings and you can also reset the counter.

Ideas on how to use it

This widget is ideal for indicating the maximum Sound Level in the classroom, but you can also use it as an applause meter. To do this, set the permitted sound to maximum and switch off the bell. The audience can applaud candidate 1 first, and then candidate 2 - you can compare which candidate had the loudest applause.

Advanced tip

Activate the Annotation bar and use the arrow feature to indicate how far the sound level is reached per candidate.
