What is an Air Whistle?
An air whistle is a sound-producing device that uses compressed air to create a high-pitched, attention-grabbing tone. It is widely recognized for its sharp and clear sound, which can travel long distances. Typically, air whistles are used in transportation, sports, and emergency situations to issue commands or warnings.

The air whistle operates on a simple principle of acoustics. Compressed air is forced through a narrow opening, causing vibrations that produce sound waves. These waves are then amplified by the whistle's body, creating a loud and distinct tone. The design and size of the whistle determine the pitch and intensity of the sound.

The origins of the air whistle date back to the early 19th century when it was first used as a signaling device on trains and ships.
