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.

The steps in evaluating sudden hearing loss include: (1) appropriate history and physical examination (eg, otoscopic examination, tuning fork tests), (2) urgent audiometry to confirm hearing loss, (3) immediate referral to an otolaryngologist for further testing (eg, tympanometry, blood tests, MRI), and (4) initiation of treatment.
