Rinne’s and Weber’s tests are simple tuning fork tests used to screen for the presence of conductive and sensorineural hearing loss. They are usually performed as part of a comprehensive ear examination.Β 

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.

How to perform Rinne’s test

1. 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). This tests bone conduction.

2. 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.

3. When the patient can no longer hear the sound, move the tuning fork in front of the external auditory meatus to test air conduction.

4.Β Ask the patient if they can now hear the sound again. 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 β€œRinne’s positive” result).

Interpretation of Rinne’s test

In healthy patients,Β air conductionΒ (using the structures in the ear)Β should be better thanΒ bone conduction (conduction of vibrations via bone). Therefore, the patient should be able to hear the tuning fork held over theΒ external auditory meatus (which is testing air conduction) for longer than the tuning fork held on theΒ mastoid (testing bone conduction).

If there is aΒ problem with air conduction (i.e. conductive hearing loss), then bone conductionΒ may be better thanΒ air conduction. In this situation, the patient will be able to hear the tuning fork for longer when held on theΒ mastoid (testing bone conduction) than when held over theΒ external auditory meatus (testing air conduction).Β 

However, a patient with significant sensorineural hearing loss may have a ‘false negative’ Rinne’s test, as they are unable to hear anything in the affected ear but bone vibrations may be transmitted to the unaffected ear.Β 

How to perform Weber’s test

Explain to the patient that you are going to test their hearing using aΒ tuningΒ fork.

1.Β Tap a 512Hz tuning fork and place in the midline of the forehead.Β The tuning fork should be set in motion by striking it on your knee (not the patient’s knee or a table).

2.Β Ask the patientΒ β€œWhere do you hear the sound?”

A 512Hz tuning fork is used as it gives the best balance between time of decay and tactile vibration. Ideally, you want a tuning fork that has a long period of decay and cannot be detected by vibration sensation.

Interpretation of Weber’s test

Weber’s test should be assessed in context with the results of Rinne’s test before any diagnostic assumptions are made:

  • Normal: sound is heard equally in both ears.
  • Sensorineural hearing loss:Β sound is heard louder on the side of the intact ear.
  • Conductive hearing loss: sound is heard louder on the side of the affected ear.*

*In conductive hearing loss, there is a relative improvement inΒ bone conduction on the affected side. The affected ear has less environmental noise (due to the problem with air conduction). In addition, low-frequency sounds are ‘trapped’ within the inner ear by the obstruction leading to increased loudness in the affected ear. You can demonstrate this by speaking/humming, and then occluding an external auditory meatus. You will notice your voice is louder in the occluded ear.Β

Key points

  • Rinne’s and Weber’s are tuning fork tests (512 Hz tuning fork) used to screen for conductiveΒ andΒ sensorineural hearing loss.
  • In healthy individuals, Rinne’s test is positive (indicating air conduction is better than bone conduction) andΒ Weber’sΒ is heard in theΒ midline.
  • In patients withΒ conductive hearing loss, Rinne’s test is negative (indicating bone conduction is better than air conduction) on the affected ear andΒ Weber’s test localises to the affected ear.
  • In sensorineural hearing loss,Β Rinne’s test is positive (indicating air conduction is better than bone conduction) andΒ Weber’sΒ is heard in the unaffected ear.
