Wanted this since the first month of data, and a reader named Paulo reminded me to actually build it: a page where you pick two aircraft models, or two airlines, and put them head to head. Flights tracked, average noise, the loudest pass either one has ever recorded, how hard they shake the terrace on average and at their worst. Only things with at least 15 tracked flights make the list — a plane that flew over once at 95 dB doesn't get to call itself the loudest thing in the sky.
Each side gets a gauge showing where it lands against everything else the station has ever measured — louder than this percentage of everything tracked, or flat out the loudest of the lot — plus a plain-English line that does the subtraction for you: this one runs about this many dB louder than that one, on average. Where the data exists: manufacturer, first flight year and a photo for the aircraft; founding year and headquarters for the airlines. And a share button, because "the A320 is measurably quieter than the 737" is the kind of sentence that deserves to be forwarded to someone.
Smaller fix while I was in the neighborhood: the Archive page's month-by-month chart used to draw one horizontal bar per month since launch, five rows already and heading toward a wall of them a year from now. Gave it the same fixed 12-month grid the Noise Report already uses, so it stays the same size no matter how long the station keeps running.
