Sound Meter Pro v2.4.5

Sound Meter Pro is the 4th set of Smart Tools® collection (noise, vibration, seismometer). SPL(sound pressure level) meter app uses your built-in microphone to msure noise volume in decibels(db), and shows a reference. We had calibrated many android devices with the actual sound level meter with dB(A). REMEMBER!! The smart phone micro were aligned to human voice (300-3400Hz, 40-60dB).
Therefore the maximum values are LIMITED by the hardware limitation, and very loud sound(100+ db) cannot be recognized. Moto Droid (max.100), Galaxy S3 (81dB), Galaxy Note (91dB), Galaxy S2 (98dB), Desire(82dB)… Vibrometer app uses the phone sensors to msure vibration or the rthquake, and it shows a reference as a seism detector. The msured values are the Modified Mercalli Intensity scale(MMI), and just for reference.
If it is inaccurate, you can calibrate it so that the maximum value is about 10-11. * Pro version added Ftures:
