Why does a window left slightly open whistle on a windy day?
While there are a few ways to think about what sound is, for our purposes we will think of it as the rapid back and forth movement of a group of air molecules. What is happening in the case of the window is that the flow of air hitting an edge on the window is unstable. As you can imagine the fluid mechanics involved is quite complicated and quite frankly beyond me. However, the principle is the same as when you generate a sound by blowing on the top edge of an empty bottle. In that case what is happening is that part of the stream of air is quickly flipping back and forth between going over the lip of the bottle and going into the bottle. When it starts going over the lip of the bottle, forces are created the causes it to start going into the bottle. However when it starts going into the bottle, there are forces that are created that cause it to start going over the lip of the bottle. This happens over and over again very quickly. The forces that pull the air stream back and forth are called "negative feedback" forces. All wind instruments use the combination of air flow and negative feedback to generate their sounds. How quickly the flow moves back and forth depends on the dimensions of the cavity, the size of the column of air hitting the edge and the speed of the air flow.
