Sound Meter Pro is the 4th set of Smart Tools collection. SPL(sound pressure level) meter app uses your microphone to measure noise volume in decibels(db), and shows a reference. We calibrated a lot of android devices using an actual sound meter with dB(A). Remember! Most smart phone microphones were aligned to human voice (300-3400Hz, 40-60dB).
