A clinical test used to evaluate hearing loss
Weber Test[edit]
The Weber test is a quick screening test for hearing loss that can help differentiate between conductive hearing loss and sensorineural hearing loss. It is named after the German otologist Friedrich Weber.
Procedure[edit]
The Weber test is performed using a tuning fork, typically set to a frequency of 512 Hz. The test is conducted as follows:
- The tuning fork is struck against a surface to start it vibrating.
- The base of the vibrating tuning fork is placed on the midline of the patient's forehead, typically on the bony prominence.
- The patient is then asked to report in which ear the sound is heard louder.
Interpretation[edit]
The results of the Weber test can be interpreted as follows:
- Normal Hearing: The sound is heard equally in both ears.
- Conductive Hearing Loss: The sound is heard louder in the affected ear. This occurs because the conduction of sound through the bone is enhanced when the normal air conduction pathway is impaired.
- Sensorineural Hearing Loss: The sound is heard louder in the unaffected ear. This is because the affected ear has a reduced ability to perceive sound due to damage to the inner ear or auditory nerve.
Clinical Significance[edit]
The Weber test is often used in conjunction with the Rinne test to help determine the type of hearing loss a patient may be experiencing. While the Weber test can provide useful information, it is not a definitive test and should be used as part of a comprehensive audiological evaluation.
