Sound Meter & Noise Detector is a practical tool for your smart android device to detect sound and noise at any time and in any place. More comprehensive and easier to use.
Also known as a sound level 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 :
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.
