OpeNoise

This application is designed to measure real-time sound pressure levels using A-weighting. It also has the ability to display minimum and maximum levels, as well as perform third octave and FFT analysis. Users can save their data in a text file and calibrate their device for more accurate measurements. The app also allows for the display of measurements on a map and the compilation of metadata. Additionally, users can share their calibrations and measurements with the OpeNoise community.

However, it is important to note that this app is not intended for professional use and may not always provide completely accurate noise measurements. This is because each device may have a different response to noise, so it is recommended to compare the results with a professional noise level meter within the measurement dynamic range. It is also necessary to have adequate technical knowledge and skill in order to use the app properly, as an impromptu measurement may not be accurate.

The calibrations and measurements shared with the OpeNoise community will only be used for statistical purposes and cannot be used to verify compliance with legal limits. The developers of this app are Arpa Piemonte, the Regional Agency for the Protection of the Environment of Piedmont, Italy. The code for the app is open source under the GNU v.2 license or later, and can be found on GitHub at https://github.com/Arpapiemonte/. It is encouraged for developers to be original and SEO-oriented when using the code.
