# sound Level
|
||
|
|
||
|
Find out what the the level of sound heard by the microphone is.
|
||
|
|
||
|
```sig
|
||
|
input.soundLevel()
|
||
|
```
|
||
|
|
||
|
## Returns
|
||
|
|
||
|
* a ``number`` between `0` (low sound) and `255` (loud sound) which tells how loud the sounds are that the microphone hears.
|
||
|
|
||
|
## Example
|
||
|
|
||
|
Show a checkerboard icon while the sound level is greater than `100`.
|
||
|
|
||
|
```blocks
|
||
|
basic.forever(function () {
|
||
|
if (input.soundLevel() > 100) {
|
||
|
basic.showIcon(IconNames.Chessboard)
|
||
|
} else {
|
||
|
basic.clearScreen()
|
||
|
}
|
||
|
})
|
