Caution:

The value of sound meter is not as precise as an actual Sound Pressure Level Meter (SPL meter) sound meter, this is due to most device's microphone are aligned to the human voice. To fix this, use an actual sound meter or Sound Pressure Level meter (SPL meter) to adjust decibels error as close as possible before use. If you didn't own an actual Sound Pressure Level meter (SPL meter), go to a very quiet place where sound cannot hear and adjust the reading value to 20~30dB.
