Sound Meter Pro is the 4th set of the Smart Tools® collection.
The SPL (Sound Pressure Level) application uses your built-in microphone to measure the volume of noise in decibels (db), and shows a reference. I had calibrated many Android devices with a real sound level indicator (dBA).
Vibrometer uses phone sensors to measure vibration or an earthquake, and it shows a reference as an earthquake detector (seismometer).
Use the results only for reference, as Android devices have a wide variety of performance and sensitivity.
