Sound level meter

Sensitivity

Because the microphones on all devices have slightly different sensitivities, it isn't possible to calibrate them to all show the same levels (e.g. dB), however, you can get a feel for the volume levels using the graphical display.  You can adjust the range that is detected by adjusting the slider at the bottom.

Reset

The app will display a rolling average level alongside the current volume value.  You can reset the average, by clicking on the reset button.
