Description
Sound Meter Pro is the 4th set of Smart Tools collection (noise, vibration, seismometer).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
- Line-chart duration
- More models are calibrated
- No ads

Great Apps This pro version comes with dB meter plus with vibrometer. You can even extract the chart out of it. It's really worth the money if you wish to study the dB level and vibration based on MMI around you. However, if the vibrometer has an extra feature based on how many mm/s instead of MMI alone will be more useful.

No longer licenced??? One star on this and all the other smart apps that have 'mysteriously' de-authorised me! Yes I've followed all the instructions to re-auth me to no effect. Not happy buyer beware

works great on tansformer prime I own a recording studio and this tracks what is known as far as the studio's spl for playback of recorded material. I'm pretty impressed, as I've had this control room measured before and have other tools that agree with this product without calibrations. Nice product and I will recommend it to friends Roger W.

Sound Meter Pro Quite good but calibration is a bit fiddly.

Craptastic licensing I really like this and paid for the ad free version but the POS won't run if you don't have a data connection. Really? How about not requiring a phone home to run. Not recommend unless the author adopts a sane licensing policy.

Handy on your phone Have used it setting up my pa loads of time, works well and handy as its on your phone so you don't have to get the main db toys out. It's by your side all the time so you can take a reading for all round level. It would be nice if you could store readings of interest so you could look back on them as well as to compare with. But all in all worth having.
