SPL(sound pressure level) meter app uses your phone mic to measure 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 microphones were aligned to human voice (300-3400Hz, 40-60dB). Therefore the maximum values are LIMITED by the manufacturers. The very loud sound cannot be recognized. Moto Droid(max.100), Galaxy S(81dB), Galaxy S2(98dB)...



Vibrometer app uses your built-in sensors to measure phone's vibration or the earthquake, and shows a reference.

The measured values are the Modified Mercalli Intensity scale(MMI). If it is inaccurate, you can calibrate it so that the maximum value is about 10-11.
