I phone sound meter

I know that sound meter apps are notoriously unreliable due to lack of calibration, but decibel 10th seems to have a calibration adjustment.

I was curious if anyone with a dedicated sound meter could compare the differences if any. My experience seems like it is very close. For example my garbage disposal is 85d, ambient back yard is 55-65d. All reading i have measured seem to be very close to sound levels if have found on the web.

The part of the app that i think is a nice feature is the ability to increase/decrease decibel readings to adjust baseline readings, IE: calibration adjustment
