About this app

NoiseCapture App is an application dedicated to the evaluation of your noise environment. It allows to perform measurements and, thus, to give information on your noise exposure. In addition, you can contribute to the realization of collaborative (or community) noise maps by anonymously sharing your measurements.

New !:
If your smartphone is already calibrated, you can now calibrate other smartphones with the application, based on the ambient noise. Select Automatic Calibration in the Calibration menu, in "Transmitter" mode for the reference smartphone and "Receiver" mode for the smartphones to be calibrated. Approach the smartphones together and start calibration from the reference smartphone. The rest is automatic.

• Noise measurement and calculation of acoustic indicators (Leq, Lamin, LAmax, LA10, LA50, LA90...) on a journey
• Measurement description (text, photo, tags)
• Viewing measurements on a map
• Measurement history
• Smartphone calibration with a reference device
• Detailed help on using the application

Recommendations for the 'best' measurement (see Help for details):
• The smartphone should not be in the pocket but hand held
• The smartphone microphone should not be hidden
• The noise measurement must be carried out without adding noise!
• It is possible to use an external and calibrated microphone

Contribute to collaborative noise maps:
• Allow the transfer of measures into the community
• Realize mmeasurement outside buildings
• Do not measure when rainning or with wind
• Goto the collaborative noise map :

Contribute to the NoiseCapture project:
• conttribute to the code development:
• share your comments, questions:
• organize NoiseCapture Party to map your sound environment:
NoiseCapture App respects your private life:
• You fully control how the information is sent to the server
• Only anonymous data is transferred
• There are no audio recording: only acoustic indicators are calculated and transferred
• NoiseCapture App requires only strictly necessary permissions

• Although NoiseCapture App is developed by specialists, keep in mind that a smartphone will never replace a professional sound meter. If you need advanced expertise, contact a professional.
• The quality of the measurement depends on the technical performance of your smartphone and its calibration. Depending on the nature of your phone and the version of Android used, it is possible that you can not measure with sufficient accuracy.

NoiseCapture App is the result of collaboration between two French research laboratories, the Laboratory of Environmental Acoustics (Ifsttar) and DECIDE team of Lab-STICC (CNRS), with a support from the European Commission.

This does a good job at recording averages of background noise, but not for any specific sounds you're trying to measure, especially if they're short. My upstairs neighbor has been dancing a lot with loud footsteps, and I wanted to record it. While using this app, it registered spikes in decibels upwards of 70, but these were not saved or reflected at all in the final results, as each individual spike did not last a full second. I was also not able to view the original graph that reflected this

Is faulty. Asks for GPS all the time even though permission while in use has been given. Says no GPS even though GPS is on. Finds GPS after start noise measurement. Should find GPS after starting app to indicate status. Keyboard can not be easily closed by tapping on screen after entering noise measurement details. No confirmation that details have been transmitted. More measurement conditions like outdoor, inner or outer city, nature,

Dear Benjamin, thank you for your feedback. We have released a new release. Could you test again and let us know if the problem is solved?

I like this application!! congratulations. I have found that this is not simply tool but a community measuring the noise along Europe!!! Make it more visible! it could be great. I work in geomatics and the exportation to geo-json works fine. Some suggestions: Would it be possible to export the expectrogram as a raster to extract your own statistics?. Would it be possible, on the other hand, to save user-static measurements? Imagine we try to take indoor registration: the GPS is not going to work so the user stays fixed in a point for few second (a point with the mean/median value of dB per Hz is saved in a register/row), then he stops, walk to the next and repeats the operation. A unique geo.json or shp would be exported, the indoor coordinates would be added and shown in any other application, fugro viewer for example. I will continue playing.
