fork

 [fork]
a pronged instrument.
tuning fork a device that produces harmonic vibration when its two prongs are struck; used to test hearing and bone conduction. See tuning fork tests.

tun·ing fork

a steel or magnesium-alloy instrument roughly resembling a two-tine fork; the vibrations of the tines, when struck, produce a pure tone and overtones; used to test hearing and vibratory sensation.

tuning fork

[t(y)o̅o̅′ning]
Etymology: Gk, tonos, stretching; L, furca, fork
a small metal instrument consisting of a stem and two prongs that produces a constant pitch when either prong is struck. It is used by physicians as a screening test of air and bone conduction.

tun·ing fork

(TF) (tūn'ing fōrk)
Steel or magnesium-alloy instrument roughly resembling a two-pronged fork, the vibrations of the prongs of which, when struck, give a musical tone of restricted bandwidth; used to test hearing and vibratory sensations.

tuning fork

tuned, steel instrument formed as a base piece, and two parallel tuned tines which vibrate when struck, sounding a single note of known frequency; 128-Hz tuning fork is used to evaluate vibration perception (base piece is placed against a bony prominence whilst tines are set in vibration); normal subject should be able to detect vibrations at distal parts of foot (see Rykel-Seiffer)
