Sound Meter

Sound Meter


Sound Level Meter is in the 4th set of the Smart Tools collection (noise, decibel meter).

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 built-in 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)...

See the 4-6th pictures. I had calibrated many android devices with an actual sound level meter. You can trust the result in routine-noise levels (40-70dB). But, please use it as an auxiliary tool.


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

App with a gauge to display real-time DB grade.(tool). Misura l'intensità del suono, rumore, in temporeale, decibel.

Misura di decibel dei suoni che ci circondano

Seems to work but it is limited by the microphone. I tried it today whilst testing a fire alarm in a noisy plant room. Ambient level measured 72dB. Fire alarm sounding, my ears bleeding, sound level still showed 72dB. It would be useful for noise testing your motorbike, as they would all pass. :-)

Only to be used once in a while, I don't really think it's accurate though.

App needle response could be smoother and quicker. Also, the dev needs to configure for A and C weighting (very basic that is included in even the cheapest Radio Shack db meter!)--------- I would also like to see a decibel meter that can remember readings ala paper-tape/lap-times of a stop watch method, many different readings in a row, and then put those on a graph?
