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.

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.
