Proper lighting is necessary to observe the patient's responses and ensure they remain comfortable throughout the procedure. When a tuning fork is positioned on the skull, sound travels through cranial bones to both inner ears.
Weber Test Procedure Ear Lateralization Tips for Accurate Assessment
Immediately place the vibrating fork on the midline of the patient's forehead, ensuring consistent contact with the bone. 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.
Repeat the test several times to confirm consistent results. Step-by-Step Procedure Strike the tuning fork firmly against a rubber pad or the clinician's knee to initiate vibration.
