Don’t know about the accuracy of the decibel reading but the app spells disturbing incorrectly in the graph.

This app reads many dB too high. A quiet room with virtually no background noise shows as “distrubing” (yes that’s a typo in the app) This app is useless until there is a way to calibrate it. The 5-star reviews appear to be fake.

Registers in the 50s or 60s when there is no sound in the room. Later after I interacted wit Siri and came back to Siri, it registered -55! How can you have negative sound? And why does the meter say 60 dB is “distrubing”?
