The Loudness block is a Sensing block and a Reporter block. The block reports how loud the noise is that a microphone receives, on a scale of 0 to 100.
To use this block, a microphone must be connected. Later, a message will appear on the screen, asking for permission to use the microphone. If permission is denied, the block will report a loudness of 0 or -1. If the user does not have a microphone, earbuds inserted into the microphone port will work too.
This block can be displayed as a Stage Monitor.
