Note:

The value of decibel meter or sound meter(dB meter) is not as precise as an actual Sound Pressure Level Meter(SPL Meter), sound meter, decibel meter or noise level meter, this is due to most device's microphone are aligned to 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 20~30 dB.
