Levels of Noise In decibels (dB) according to American Academy of Audiology :
120 dB - Jet planes taking off
110 dB - Concerts, Car horns
100 dB - Snowmobiles
90 dB - Power tools
80 dB - Alarm clocks
70 dB - Traffic, vacuums
60 dB - Normal conversation
50 dB - Moderate rainfall
40 dB - Quiet library
30 dB - Whisper
20 dB - Leaves rustling

� Owing that performance of the microphone will be different for each device, so calibration is needed before use. Because we cannot evaluate the performance of each device, we cannot provide a standard value for calibration. The calibration method can only be based on your intuition to increase or decrease the decibel value or use other equipment for comparison.
