If you touch the microphone at the start screen, a measurement is started for the duration of 10 seconds. Choose the start of your measurement preferably in a way that the plane will pass you in these 10 seconds. Please keep your measurement pure and be careful not to measure any other noises. If by accident you measure non-aviation noise, please don’t send the registration to our database. It would pollute our database and would make it less trustworthy. The app only registers airplanes on a maximum attitude of 15.000 meters within a radius of 15 kilometers. If the app has detected an airplane in this area, the data of the airplane are shown to you, together with the maximum noise level in decibels and the data of your phone. If you press ‘submit’ after these data is shown to you, the data will be send to the central database, together with your geographical position and the date and time of your measurement. With all these measurement interactive reports are created on https://reports.explane.org/ Make your selections and give insights in the noise nuicance to all stakeholders, i.e. politicians, press, residents, airports and airlines. ## Key features - 10-second noise measurement - Airplane detection within 15km - Records noise level in decibels - Submits data to central database - Generates interactive noise reports - Captures geographical position ## Recent user reviews (1 of 1) All indexed reviews: https://appshunter.io/ios/app/explanenow/id1448049191/reviews.md ### 5/5 — Essential app to record and log aircraft noise pollution *2021-03-26* ExPlane affiliated with the SchipholWatch group in Amsterdam is the best app to record aircraft noise pollution. We have thousands of local communities in Brisbane affected by excessive noise pollution from Brisbane Airport, and this app allows us to engage in a citizen science project to measure noise levels in far more places than the couple of noise monitors installed by the government. The noise recordings are accurate, no registration is required, the app detects the plane flying above automatically, and the data is open access. Very well done! ## Frequently asked questions about ExPlaneNow ### How does ExPlaneNow measure airplane noise?
