Category Sensing
Type Reporter

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.

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
  say [You are a very loud and outgoing person. You like to speak up when there is the need.] for (5) secs
  say [You are a timid person, but one to be wary of. There is more than meets the eye.] for (5) secs
  • Projects that detect changes in volume
  • Depending on how loud a noise is, the greater response
turn cw (loudness) degrees
  • Setting a microphone's size to a noise's loudness
set size to ((loudness) + (100))%
