Also known as a sound level meter, sound measure app, decibel meter, and noise meter, this sound meter app has helped hundreds of thousands of people measure sound level in their environment. The decibel meter or sound meter displays a real-time sound level with the minimum value, maximum value, and average value. Levels of noise can also be found.

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.
