Which tests are tuning fork tests?

• A. Weber and Rinne tests
• B. Monaural and binaural testing
• C. Tympanometry
• D. Acoustic reflectometry

Answer: (A)

These tests use a tuning fork to quickly assess how sound is conducted through the ear and to distinguish conductive from sensorineural hearing loss. In the Weber test, the tuning fork is placed on the midline of the skull. In a person with normal hearing or equally impaired hearing in both ears, the sound is heard in both ears equally. If one ear has conductive loss, sound tends to be heard louder in that ear because the external or middle ear problem dulls perception in the other ear relative to the affected side. If there is sensorineural loss, the sound is heard louder in the normal or better-hearing ear, because the damaged ear’s inner ear or nerve pathways reduce perception. The Rinne test compares air conduction to bone conduction. You place the tuning fork first on the bone behind the ear (bone conduction) and then next to the ear canal (air conduction). If air conduction is heard longer than or equal to bone conduction, it’s a positive Rinne, which is typical for normal hearing or sensorineural loss. If bone conduction is louder than air conduction, that indicates conductive loss in that ear. Because these assessments specifically rely on the presence and perception of sound produced by a tuning fork to evaluate the pathways of hearing, they are classic tuning fork tests.
