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.

Working well gps logs missing Its a good application for logging noise complaints but it needs more information for providing the location the noise is being reported on.

Didn't work when I needed it. Tried to measure loud music in basement venue. Wouldn't work because no network connectivity!!! Why??? Copy protection more important than functionality for paying customers? Otherwise awesome app.
