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 used, and so a message will appear on the screen, asking for permission to use the microphone. If you deny it, the block will report a loudness of 0 or -1. If you do not have a microphone, earbuds inserted into the microphone port work too.

This block can be displayed as a Stage monitor.

Example Uses

This block is more precise than the Loud? block; instead of simply reporting if a noise is loud or not, the Loudness block will report how loud the noise is. Therefore, when accuracy is needed with measuring noises' volume, this block is the better choice.

Some common uses for the Loudness block:

  • Voice analyzers
wait until <key [space v] pressed?>
if <(loudness) > (30)> then // when the loudness is over 30 this will activate the <loud> block

else
  say [You are a timid person, but one to be wary of. There is more than meets the eye.] for (5) secs
