Emphasize that they should respond honestly to what they perceive, regardless of how faint the noise might be. The primary instrument is a 512 Hz tuning fork, which provides the optimal frequency for detecting subtle differences in bone conduction.
Weber Test Procedure Repeat Testing Advice for Accurate Results
Conversely, sensorineural hearing loss, resulting from cochlear or neural damage, causes the sound to lateralize to the better ear since the damaged ear cannot perceive the vibrations effectively. Before beginning, inform the patient that the test is painless and will involve hearing a humming sound.
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. Immediately place the vibrating fork on the midline of the patient's forehead, ensuring consistent contact with the bone.

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. Clinical Correlation and Limitations While the Weber test procedure provides valuable initial information, it is rarely used in isolation.
