Sound Meter Pro

Sound Meter Pro


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 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 hardware limitation, and very loud sound(100+ db) cannot be recognized. Moto Droid (max.100), Galaxy S3 (81dB), Galaxy Note (91dB), Galaxy S2 (98dB), HTC Desire(82dB)...


Vibrometer app uses the phone 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.
If it is inaccurate, you can calibrate it so that the maximum value is about 10-11.

* Pro version added Features:
- Sound Meter and Vibrometer are integrated

Only up to 105dB on Sony Xperia Z2 This app won't really be usable when it can only measure a maximum of 105, but I guess it could be down to the mic in the phone...?

The minimum, maximum and average readings over a given period are a nice touch.
