Neat writeup! From the title, I had my fingers crossed that they integrated ADS-B flight tracking data to show a map of where the sound of airplanes in the air is currently observable.
If anyone wants to go down that rabbit hole really far, I'm imagining general profiles of the sound each airplane makes, considering altitude, different sound propagation by frequency depending on distance the sound travels, and geography. Might as well throw air properties in too, to minimize the overall error. The user could provide their location and see the estimated arrival time
and frequency of the sound from the airplanes in the sky.
- kqr 4y agoOh it could get messy quickly. One of the playgrounds I like to hang out with my son at is right under the most common approach to a small local airport. It's also walled off by seven-story apartment buildings on two sides. The noise from approaching planes is dampened by the building between me and them, but bounce off the opposite building. So it always sounds like they're coming from the opposite direction, until they clear that angle, when they sound correct again, until obscured by the other building...
- bernulli 4y agoAir properties are actually super relevant, the speed of sound distribution (slower with increasing altitude) can have lensing effects for sonic booms.
- idealmedtech 4y agoWould time of day (air temperature) also have effects on it?
- savoytruffle 4y agoyes, air pressure and thus propagation speed varies with temperature. Colder air is denser, and thus faster to sound. But this is probably not a huge difference for sound as compared to airfoil performance.
