Blowing a whistle forces air through the mouthpiece's rectangular tube until it runs into a slotted edge. The slot divides the air in two, creating oscillating sound waves that then tumble around the resonate chamber, or barrel.
As the compressed air escapes from the hole on the other end, it creates an audible pitch. A whistle is a simple device that produces sound when air is forced through an opening. Their loud, attention-getting blast makes whistles essential for police officers and sports referees. They can save lives when used by lifeguards, lost campers, or crime victims.
Lots of non-whistlers think of whistling ability as a genetic trait, like attached earlobes or blue eyes. They've never figured out how to whistle, and they assume it's simply beyond their capabilities. But there's no real evidence of any factors, genetic or otherwise, that might prevent someone from learning. 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 frequency of the sound is dependent on the length of the whistle. The longer the whistle, the lower the pitch will be. The ball inside the whistle is not necessary for the whistle to work but serves a purpose. A whistle without a ball has a flat tone that may get "lost".
