1 Whistles The history of….

2 Where it began The whistle has its roots dating back to ancient China, where night watchmen would blow into the tops of acorns to alert the towns to invading Mongolians.

4 Whistles were (and still are) called by many different names, including Fipple Flute, Vertical Flute, Flageolet, Tin Whistle, Penny Whistle, Tin Flute, Feadóg Stáin (Irish name) and others The whistle works by causing the smooth flow of air to be split by a narrow blade, sometimes called a fipple, creating a turbulent vortex which causes the air to vibrate

5 Sometimes, unintentional whistles can be set up. A common one is the opened sunroof of a car: air passing over the top of the vehicle can, at certain speeds, strike the back edge of the sunroof, creating a very low frequency whistle which is resonated by the closed interior of the car.
