Sound 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 S(81dB), Galaxy S2(98dB)…
See the 4-5nd pictures. Many devices had been calibrated by the real sound level meter with dB(A).
*Sound Meter Pro version added Features:
– Sound Meter and Vibrometer are integrated

Sound Meter user reviews:
does what it says. the option of flipping the display is cool too because most phones have mics on the bottom
Great app nice functionality accurate and spontaneous readings.
Had my stereo all the way up and it said it was a normal conversation at 60dbs which I don’t think my stereo is that quit and did the same with my tv even after calibration
There are many 1* ratings because of volume limits. Goes to 98db on motorola photon.
This app comes in handy from time to time. I’d say the whole series of apps are really great.
I use it to measure how loud daily used items really are in the house. We use it to fished just how loud someone is CD another at the dinner table somtimes
