It is unlikely two different devices will produce
the same results. Use the microphone gain slider
to increase or decrease sensitivity.
Cell phones are not calibrated for accurate dB SPL
measurement. Difference phones will produce
different values. We normalize the dB SPL levels
produced by your cell phone to a range of 0-99
to make it easy to compare results obtained from
the same device.

This app contains flashing lights.
Do NOT use this app if you are
