![]() If it is inaccurate, you can calibrate it so that maximum value is about 10-11. The measured values are related to Modified Mercalli Intensity scale (MMI). Vibrometer uses the phone sensors to measure vibration or an earthquake, and it shows a reference as a seism detector. You can trust the result in routine-noise levels (40-70dB). Therefore maximum value is LIMITED by manufacturers, and very loud sound(100+ dB) cannot be recognized. REMEMBER!! Most smart phone microphones were aligned to human voice (300-3400Hz, 40-60dB). We calibrated a lot of android devices using an actual sound meter with dB(A). SPL(sound pressure level) meter app uses your microphone to measure noise volume in decibels(db), and shows a reference.
