Measure environmental noise.
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 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.

Totally inaccurate...going to uninstall
I work in theatre and sometimes its just helpful to know what the levels of a particular effect or sound cue may be. Thanks to this app, I was also able to determine how loud it got in the wings during the closing number of One Night With Janis Joplin. 103 db is impressive.
I used the lite version for 5 minutes, that's all it took for me to get the pro version. Very happy
Quite happy with it. Does what it says.
I have the pro version. In the screen shots, the notification bar is visible, but on my phone the app takes up the whole screen. I need to see the clock! Also, long pressing to reset doesn't always work. Why not just add a visible reset button? Otherwise it seems to work well.
Disappointed that the decible level does not go high enough to record harmful hearing levels. If you have a meter that can measure high levels of heavy equipment noise please let me know.
Also hard to calibrate.
