A whistle is an instrument which produces sound from a stream of gas. It can be played by using the mouth, or powered by air pressure, steam, or other means. It produces a musical sound by forcing air over or through an opening. The main characteristic of a whistle is that it creates a unique and pure tone.
There are different ways to create pure tones, but we will describe the instruments that are called aerodynamic whistles. They are considered fluid mechanical whistles because they occur in gases, such as steam or air, as well as in liquids, such as water. The only difference between them is the sound speed and the fluid density. There is an interaction between a solid material and a fluid stream that makes possible the conversion of the energy to sound. Whistles used in music are usually made of brass because of its resonance and tone qualities. Except the usage as a musical instrument, there are numerous uses of whistles. They can be used as toys, in sports events, for hunting, or for police or military use.
They are considered to be one of the oldest instruments used for producing different music sounds. They have been used for thousands of years for practical, entertainment, and spiritual purpose. One of the oldest and most distinguished whistles is the boatswain’s pipe used to issue commands in naval vessels.
The modern period of these devices began in 1878 when it was first used during a sporting event. This device replaced the usual referee’s signal of waving a handkerchief. In 1883, Joseph Hudson who was a toolmaker fascinated with whistles, invented a compact and light whistle that produced two different tones that could be heard for more than a mile.
