Want to measure sound level? This is smart sound level meter app for Android! Our decibel meter uses your built-in microphone to measure sound volume in decibels (dB) and also displays samples on helpful graph. NOTE: Microphones in most devices are aligned to human voice and the maximum values are limited by the hardware. Very loud sounds (~90 dB and more) may not be recognized. Automatic gain control used in some devices may interfere with the operation of this noise meter. About Us • Visit
