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.
There's a Pro version with added features 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 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 :

Have not had it long but like the looks and how is works. Time will tell.
This app is so far the best for checking noise of CPU or Graphic card fan noise as well as total build noise that is being generated by the RIG
Thnkz to devlpr its awsome apps.... Frst tym ever i used such kind of apps Thnkz again....
Works rather well
