Levels of Noise In decibels (dB) according to American Academy of Audiology :
120db: Thunder
110db: Rock Music
100db: Subway Train
90db: Factory
80db: Busy Street
70db: Busy Traffic
60db: Conversation
50db: Quiet Library
40db: Quiet Park
30db: Quiet whisper
20db: Leaves fall

👂 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.
