Sound Meter Pro is the 4th set of the Smart Tools collection (noise, vibration, seismometer).
The Sound Pressure Meter app (sound pressure level) uses your built-in microphone to measure the sound level in decibels (dB) and displays a reference. We had calibrated many Android devices with the actual sound level meter with dB (A).
NOTICE!! The smartphone microphones were aimed at human voice (300-3400 Hz, 40-60 dB).
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 (81 dB), Galaxy Note (91 dB), Galaxy S2 (98 dB), HTC Desire (82 dB) …
The vibrometer app uses the phone sensors to measure vibrations or earthquakes and displays a reference as a seismic detector.
The measured values are the modified Mercalli intensity scale (MMI) and are for reference only.
If it is inaccurate, you can calibrate it so that the maximum value is around 10-11.
