Tuning fork
Tuning Fork
A Tuning fork is an acoustic resonator in the form of a two-pronged fork with the prongs (tines) formed from a U-shaped bar of elastic metal (usually steel). It resonates at a specific constant pitch when set vibrating by striking it against a surface or with an object, and emits a pure musical tone once the high overtones fade out.
History[edit | edit source]
The tuning fork was invented in 1711 by British musician John Shore, Sergeant Trumpeter to the court.
Physical properties[edit | edit source]
A tuning fork is a simple example of a resonator, which oscillates at its resonant frequency. The main reason for using the fork shape is that, unlike many other types of resonators, it produces a very pure tone, with most of the vibrational energy at the fundamental frequency, and little at the overtones (harmonics).
Uses[edit | edit source]
Tuning forks have traditionally been used to tune musical instruments, but they have also found their way into medicine, where they are used in audiometry, neurology, and as a method of healing in alternative medicine.
