Sound Meter Pro is the fourth set in the Smart Tools® collection. The SPL (sound pressure level) meter app uses your microphone to measure the volume of the noise in decibels (db) and displays a reference. We calibrate many Android devices using a real sound meter with dB (A). REMEMBER! Most of the smartphone microphones were aligned with the human voice (300-3400Hz, 40-60dB). Therefore, the maximum value is LIMITED by manufacturers and very loud sound (more than 100 dB) cannot be recognized. Moto G4 (maximum 94), Galaxy S6 (85dB), Nexus 5 (82dB) ... You can trust the result in routine noise levels (40-70dB). Use it as an auxiliary tool.
