Sound Level Meter is in the 4th set of the Smart Tools collection (noise).
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(100 db) cannot be recognized. Moto Droid(max.100), Galaxy S3(81dB), Galaxy Note(91dB), Galaxy S2(98dB)...
See the 4-5nd pictures. Many devices had been calibrated by the real sound level meter with dB(A).
* Pro version added Features:
- Sound Meter and Vibrometer are integrated
- Statistic menu and Save log data
- Level notification
- Line-chart duration
- More models are calibrated
- No ads
* Do you want more tools?
Get [Sound Meter Pro] and [Smart Tools] package.
For more information, see the manual, Youtube video and the blog. Thank you.
** Not compatible with: Xperia(X8, X10 mini), LG(Optimus One, P350), GT-I9001, ZTE, etc

I got this specifically to prove to my fiancee that he does, in fact, snore very loudly!

Evo maxes out at around 80DB. For anything less than that it's useful.

Each cell phone mic has limits as to how loud of a decibel reading it can register. Check forums for the limits of your device.

All cell phones mic are limited in their input so you can't measure much

If you bear in mind that it's using your phones mic, this is a surprisingly useful app. Great graphic design. Thanks devs.

Even after calibration on my Thunderbolt, I can hold the phone in front of the loudest devices, horns, tools and it never registers over 68db.

Good baseline to determine if further dosimeter testing is needed. Seems to be fairly reliable. Actual dosimeter testing has corresponded well.
