Expert's Review
Sound Meter is just one of those apps you would have never imagined we ever have. Not so many years ago, sound meters belong to cops knocking on your door at your college parties and brainy technicians and physicists talking about sound waves. At some point within, there were those clap'o'meters used in fancy TV shows and roadhouse amateur contests. Who was able to tell that your phone would be able to measure decibels?
Honestly, it isn't a panacea, so if you actually work on something important, this app won't be precise enough and it can be easily deceived. Anyway, even when it gets lost when there's too much noise and it seems to haphazardly give results when in silence, it's a great idea and worthy of being installed. As it's lightweighted there's no harm in having it, because one never knows when it may be useful.
This a Pro version comes with added features (stats...) and no ads.
SPL(sound pressure level) meter app uses your phone mic 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 manufacturers. The very loud sound cannot be recognized. Moto Droid(max.100), Galaxy S3(81dB), Galaxy S2(98dB)...
Vibrometer app uses your built-in sensors to measure phone's vibration or the earthquake, and shows a reference.
The measured values are the Modified Mercalli Intensity scale(MMI). 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 and Save log data
- Level notification

Sound meter has a quick response but the graph plot does not rescale after the duration has been reset. Developers should fix this.

I have other tools from this author and, while I don't use them often, I'm quite pleased with them whenever a need - or a fit of fiddly procrastination arises. So, I had high hopes for this sound meter. I don't have a way to calibrate, so I was going t

Your DB limits is caused by your PHONE hardware limitations, not the software, read the description, and it's mostly on Samsung phones, Motorola does not have these limitations on hardware

Will not read any volumes over 84 decibles. I thought it might be a limitation to the free version, but now I have paid version and same thing.....bummer..... PLEASE fix this so I can leave a better review.......

What's the point of a sound level meter that does not offer A-weighting? This is a fundamental feature found on even the cheapest SPL meters. The results are pretty useless without it.

Works, has a graph & saves data. DOES NOT SEEM TO REGISTER ANYTHING ABOVE 85dB.
