With conductive hearing loss, such as that caused by otosclerosis or fluid in the middle ear, the sound lateralizes to the impaired ear because bone conduction remains efficient while air conduction is diminished. In a patient with unilateral hearing loss, the sound often appears louder in the affected ear if the loss is conductive, or in the better ear if the loss is sensorineural.
Weber Test Procedure Avoiding Common Errors
Practitioners must handle the tuning fork carefully to prevent burns from the vibrating metal and ensure the fork strikes with sufficient force to produce a clear tone without causing discomfort. This phenomenon, known as lateralization, provides the primary diagnostic clue that guides further investigation.
Document the direction and intensity of the perceived sound lateralization. Healthcare providers typically combine these results with the Rinne test to form a comprehensive understanding of the hearing pathology.

The test may yield ambiguous results in cases of bilateral hearing loss or when patients have difficulty perceiving subtle differences. Understanding the Purpose of the Weber Test This examination serves as a cornerstone in otological assessment, allowing clinicians to differentiate between types of hearing impairment.
