Sound Level dB



Turn your device into a noise detector!

Sound Meter dB allows you to measure environmental noise with your mobile phone.

You can use your phone microphone to measure noise volume in decibels (db) and shows a graph for you to visualize the realtime measurement.


Due to microphone limitations on by most Android phone manufacturers, the meter range is different, usually the low end of the scale cannot be achieved because of the microphone noise and the upper end of the scale is limited by the microphone distortion on high levels.
