NOTES:
- Please do not expect a quiet room reading will be 0 dBA. The range 30 dBA - 130 dBA is the standard usable range and an average quiet room will be about 30 dBA.
- Although most devices are pre-calibrated, custom calibration is suggested for serious purposes requiring higher precision and accuracy. To calibrate, you will need a real external device or calibrated sound meter as a reference, then adjust the trimming value until the reading matches with the reference.
