TECHNICAL SPECIFICATIONS:
- Real-time A-weighted sound pressure level measurement
- Minimum and maximum level
- Third octave and FFT analysis
- Data saving in text file
- Calibration
- Displaying measurements on a map
- Metadata compilation
- Sharing calibration and measurements with the OpeNoise community
TERM OF USE
This app is not intended for professional use, it does not necessarily guarantee an accurate noise measurement.
Since each device has a different response to noise, a comparison with a professional noise level meter in the measurement dynamic range is required.
The utilization of the app requires adequate technical knowledge and skill; an extemporary measurement might not be correct.
The calibrations and measurements sent to the OpeNoise community will be used for statistical purposes only and cannot be used in any way to verify compliance with legal limits.

Ratings and Reviews
Works
This app does what it says it does and no more. I like it’s settings UI controls, though I wish it could display measurements faster than once per second.
Developer Response ,
Thanks!
Useless
The app made no sense. You click Start, as if you’re saving the readings. Then at some point you click Stop, and save. But then when you try to recall what you saved, it’s just a bunch of numbers that mean nothing. Deleted the app after using it for several minutes. Just useless.
Developer Response ,
We are sorry that you are unable to use the app. The data saved in the text file represent sound levels. A brief explanation of how to use the app is on the information page, however, you must have some expertise in mathematics and acoustics to understand exactly what the data means.
