What is the name of the test where the bone vibrator is placed in the middle of the patient's forehead?

The Weber test is designed to assess the type of hearing loss a patient may have and is particularly useful in distinguishing between conductive and sensorineural hearing loss. In this test, a bone vibrator is placed on the midline of the patient's forehead. The patient is asked where they hear the sound – on the left side, right side, or equally in both ears.

If the sound lateralizes to one side, it suggests that the ear with the louder sound may have conductive hearing loss (impairment in the outer or middle ear), while the side that hears the sound softer may have sensorineural hearing loss (impairment in the inner ear or auditory nerve). This method of using a bone vibrator directly on the forehead helps in assessing and diagnosing the patient's hearing abilities effectively.
