This is the so-called “sound tracing”. However, when we hear the roar of the heavenly plane and look up reflexively, we often cannot see the plane immediately, so we have to search for it for a while to find out. “Soundtrack” is not working at this time Because the sound source (ie, the aircraft) itself is also moving at a high speed, and the aircraft is far away from the observer. When the sound spreads to the human ear, the aircraft has left the position at that time. It was recently proposed that the ground
