Volunteers wanted for calibration smartphones

One of the uncertainties of the Explane-data is how precise can we measure aviation noise levels with a smartphone. To quantify those uncertainties we will organise a calibration day in the Amsterdam Schiphol Airport region on June 29th, 2019.

On this day under supervision of the Dutch Noise Abatement Society (Nederlandse Stichting Geluidshinder, https://nsg.nl) we will test as much smartphones as possible against a calibrated noise meter.

Bring your phone with Explane
All we ask from you as a volunteer is to bring your own smartphone with Explane installed on it. We will measure together with the calibrated noise meter for approximately an hour. Read more >

Tips & tricks: point your device’s microphone at the airplane

If you use Explane to measure the sound level of a passing airplane, please point the microphone of your smartphone at the plane to get the most reliable measurement.

This tip originates from the Dutch Noise Abatement Society (Nederlandse Stichting Geluidshinder, https://nsg.nl). Thanks!

Not pointing at the airplane will likely registrate lower than real noise levels, so you will measure in favour of the aviation industry.

In rare cases we see registrations with very low noise levels, like 8 dB. Those measurements will likely originate from smartphones with a defect in the microphone or when a user has put a finger over the microphone during the measurement. You can choose to not send in such measurements by not clicking the button, and go back to the home screen of the app. Read more >

Preview new version of Explane site

Dear followers and users of the Explane app. We have made available a preview of the new open access website with all data that is gathered by you using the app. Please visite https://reports.explane.org/preview.html.

We would appreciate it very much if you provide us with feedback. Is the new site easy to use, do you understand all the presented data, do you need more explanation about what you see? Please mail us at [email protected].

You can visit the current site at https://reports.explane.org to see the changes.

Explane data now publicly available

A few moments ago we have put our new website live that gives you open access to all measurements made with this app.

Please visite https://reports.explane.org and play with the data. Let us know what you think about it, what has to be made better and what information you like or dislike.

Please mail us your feedback via [email protected] or via our form at https://cms.explane.org/feedback.

We need your feedback to improve our site from this first version to the next version! We appreciate that you made over 12.000 measurements in the first phase of this civic science project.

Soon available: web site to explore Explane data

We are nearing the completion of the first version of the web site which will enable you to explore all the data that is gathered with the Explane-app.

The site will allow you to browse all the data, visualize it and choose that information that is interesting to you.

You will be able to choose your own region, to see which airplanes produced the most noise and how many measurements were made in your city.

Currently we are testing the site. Once finished we will publish the site address here and on social media. Please have patience for another week and you will get rewarded!
