There's a law of physics that says if you add the kinetic energy of a fluid to the compression energy the sum of the two is constant. This means that if you make the fluid move faster its pressure drops. So the outside air whizzing past your back windows sucks air out of your car. The pressure drops and your ears pop, just like when you climb a long hill and the air pressure drops. This is called Bernoulli's principle.

When the flute is played, the air oscillates or vibrates to make a sound. When the air flows past the windows, it causes the air in the car to vibrate at much lower frequency than a flute, but vibrate enough to hurt your ears.
