These cases result in a false negative, therefore, bone conduction will be more than air conduction. In some cases of unilateral or total sensorineural hearing loss, the Rinne test is not dependable in distinguishing conductive and sensorineural hearing impairment. There is reduced volume transmitted by the bones of the skull to the other ear.įollowing table shows a direct difference between Weber & Rinne test Limitations Of Rinne And Weber Test

Bone conduction allows the vibration sound to be transmitted to the inner ear.

Air conduction uses the apparatus of the ear to amplify and direct the sound.

This test is conducted by placing a tuning fork on the mastoid bone: In the conductive hearing loss, bone conduction is better than air or BC > AC, a negative Rinne, and the patient will report that they do not hear the fork once it is moved. Therefore, AC > BC which is how it is reported clinically for a normal or positive Rinne result. As a result, it can be determined if the cause is sensorineural or conductive.Ī normal or positive Rinne test is when sound is still heard when the tuning fork is moved to air near the ear, indicating that AC is equal or greater than. It is combined with the patients perceived hearing loss. These tests can be done in the office, and are easy to perform.Īlso called as Rhinne Test by some people, is used in cases of unilateral hearing loss and establishes which ear has the greater bone conduction. Therefore, these tests guide the doctor in further examination and investigation of the treatment process. They help in determining the difference between sensorineural and conductive hearing loss.

The patient reports that bone conduction is better than air conduction giving a false negative Rinnes test.

On testing bone conduction on the right the sound travels to the good left ear and sounds louder than when the fork is held next to the external auditory meatus on the side being tested

For example, imagine the right ear is dead.

The difficulty in interpreting Rinnes test is in total unilateral sensorineural hearing loss.

The challenge in making these interpretations is in the case of a false positive Rinnes test where there is unilateral sensorineural hearing loss. So, a patient who hears the tuning fork loudest when it is placed 1cm from the external auditory meatus has a positive Rinnes test and a person who hears loudest when placed over the mastoid process has a negative Rinnes test. In a normal ear, air conduction is greater than bone conduction, that is to say sound is more efficiently transmitted to the cochlea via air than via bone.

These tests should, however, be performed with a full cranial nerve and neurological exam. It doesnt matter which test you perform first. Children with mixed, or bilateral hearing loss, should be referred to an ENT specialist for a more formal pure tone audiometry assessment. They help distinguish between conductive and sensorineural hearing loss and so are more useful in patients with unilateral hearing difficulty. Weber and Rinne tests are reliable and useful tools for assessing hearing loss in older, verbal children. Weber and Rinne Test – Clinical Examination
