Air enters the whistle at one end. As the air reaches the other, closed end, all the air molecules “pile up” on top of each other and cause a high-pressure region. The air escapes out the little hole in the end, making the noise you hear.

The change in the pitch of sound was due to the Doppler effect. When the bomb is dropped from the airplane, the velocity of the bomb goes on increasing due to gravity until it reaches its terminal velocity. As the bomb approaches towards the ground, the pitch increases and thus the “kooouuuueeee” sound.
Why do whistles have a ball inside?
Such a whistle does not need a ball in the chamber to produce an effective sound. However, if a ball is present, it too swirls around inside the chamber, alternately blocking and unblocking part of the exit slot. This action produces a warbling alternation of tone that makes the whistle’s sound more attention grabbing.
