Sound Meter Pro v2.4.9a Apk



Sound Meter Pro is the 4th set of Smart Tools collection (noise, vibration, seismometer).
SPL(sound pressure level) meter app makes use of your telephone mic to measure noise extent in decibels(db), and presentations a reference.
We had calibrated many android units with the real sound stage meter with dB(A).
REMEMBER!! The sensible telephone microphones have been aligned to human voice (300-3400Hz, 40-60dB).
Therefore the utmost values are LIMITED by the producers and the very loud sound(100+ db) can’t be known.
Galaxy S3(max.81dB), Galaxy Note(91dB), Galaxy S2(98dB), Moto Droid(100dB), HTC Desire(82dB)…

Vibrometer app makes use of the telephone sensors to measure vibration or the earthquake, and it shows a reference as a seism detector.
The measured values are the Modified Mercalli Intensity scale(MMI), and just for reference.
Whether it is inaccurate, you could calibrate it in order that the utmost value is about 10-11.
