Product Description

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

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)...

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).

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.

For more information, see the manual, Youtube video and the blog. Thank you.

There's no telling whether it's accurate or not, and there's no obvious way to calibrate it, especially without a reference source of sound and comparison with a professionally-calibrated sound meter. So it's a 'useful guide' to sound levels - no more, no less.

Quite good. It shows the Max,min and current sound levels on a rotary scale. How accurate it is I don't know as I don't have a standard sound to check it with. Having said that, conversation levels are typically 70db and the app was reporting that sort of level. It does have an option to allow calibration so it should be possible to get accurate measurements.

Good app, works fine on my Kindle HDX. Not sure how accurate it is but it gives me a guide to my noisy neighbours, who enjoy playing loud music (!).
