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
- Statistic menu with saving log data
- CSV file exporting

- No ads

Over 80 dB on a galaxy I like the app but disappointed that the meter dies at 80 dB on a galaxy note 3. I know it's the phone and not the app.

Never registers over 80, even when my ears are ringing! Wish I hadn't paid for it.
