A Schwa back test

B Grant's test

C Rinne's test

D Weber's test

Ans. B Grant's test

Tuning Fork tests include.

a. Rinne's test - Compares air conduction of the ear with bone conduction

b. Weber test

c. Absolute bone conduction test - Here bone conduction of the patient is tested after occluding the meatus and then compared with BC of the examiner

d. Schwabach test - Here also BC of the patient is compared with the BC of a normal hearing person 'but meatus is not occludeD.

e. Bing test - It is a test of BC and examines the effect of occlusion of ear canal on hearing (. external meatus is occluded and released alternatively)

f. Gelle's test - It is also a test of BC and examines the effect of increased air pressure in ear canal on hearing.

Other Tuning Fork Tests

a. Stengertest

b. Teel's test For detecting malingering

c. Lombard's test

Also Know

a. To test air conduction - A vibrating tuning fork is placed vertically about 2 cms away from the opening of external auditory meatus.

b. Sound waves are transmitted: From tympanic membrane ~ middle ear ~ ossicles of inner ear.

c. Thus AC tests both conducting mechanism and cochlea

d. To test bone conduction - Vibrating tuning fork is placed on the mastoid bone.

e. Cochlea is stimulated directly by vibrations conducted through the skull

f. Hence - BC is a measure of cochlear function only.
