Procedure Placement of the tuning fork in front of the ear, to test air conduction. The Rinne test was named after German otologist Heinrich Adolf Rinne (1819–1868) the Weber test was named after Ernst Heinrich Weber (1795–1878). Ī Rinne test should always be accompanied by a Weber test to also detect sensorineural hearing loss and thus confirm the nature of hearing loss. Thus, one can quickly screen for the presence of conductive hearing loss. It compares perception of sounds transmitted by air conduction to those transmitted by bone conduction through the mastoid. The Rinne test ( / ˈ r ɪ n ə/ RIN-ə) is used primarily to evaluate loss of hearing in one ear.

In sensorineural hearing loss, Rinne’s test is positive (indicating air conduction is better than bone conduction) and Weber’s is heard in the unaffected ear.This article needs additional citations for verification.In patients with conductive hearing loss, Rinne’s test is negative (indicating bone conduction is better than air conduction) on the affected ear and Weber’s test localises to the affected ear.In healthy individuals, Rinne’s test is positive (indicating air conduction is better than bone conduction) and Weber’s is heard in the midline.Rinne’s and Weber’s are tuning fork tests ( 512 Hz tuning fork) used to screen for conductive and sensorineural hearing loss.Volume of voice is loud, hearing worsens in noisy environment and high frequencies lost preferentially.Volume of voice remains normal and hearing improves in noisy environment.Congenital or hereditary sensorineural hearing loss.Inner ear, cochlear or auditory nerve pathology impaired neuronal transmission to the brain Interpretation of Rinne’s and Weber’s testsĮxternal or middle ear pathology affects the conduction of sound into the inner ear You will notice your voice is louder in the occluded ear. You can demonstrate this by speaking/humming, and then occluding an external auditory meatus. In addition, low-frequency sounds are ‘trapped’ within the inner ear by the obstruction leading to increased loudness in the affected ear. The affected ear has less environmental noise (due to the problem with air conduction). *In conductive hearing loss, there is a relative improvement in bone conduction on the affected side. Conductive hearing loss: sound is heard louder on the side of the affected ear.*.Sensorineural hearing loss: sound is heard louder on the side of the intact ear.Normal: sound is heard equally in both ears.Weber’s test should be assessed in context with the results of Rinne’s test before any diagnostic assumptions are made: Tap a 512Hz tuning fork and place in the midline of the forehead ![]() ![]() ![]() If they can hear the sound, it suggests air conduction is better than bone conduction, which is what would be expected in a healthy individual (this is often confusingly referred to as a “Rinne’s positive” result). When the patient can no longer hear the sound, move the tuning fork in front of the external auditory meatus to test air conduction.Ĥ. Ask the patient if they can now hear the sound again. Confirm the patient can hear the sound of the tuning fork and then ask them to tell you when they can no longer hear it.ģ. Place a vibrating 512 Hz tuning fork firmly on the mastoid process (apply pressure to the opposite side of the head to make sure the contact is firm). It is important to be able to interpret the results of Rinne’s and Weber’s, as these tests frequently appear in OSCEs and written examinations. They are usually performed as part of a comprehensive ear examination. Rinne’s and Weber’s tests are simple tuning fork tests used to screen for the presence of conductive and sensorineural hearing loss.
