To perform a Weber test, which instrument is required?

• A. Otoscope
• B. Tuning fork
• C. Stethoscope
• D. Reflex hammer

Answer: (B)

The Weber test relies on a tuning fork to assess how sound is conducted through the skull to both ears. A tuning fork provides a stable, known-frequency vibration that, when struck and placed on the midline of the skull, allows the sound to be heard by both ears. The key idea is using that vibrating fork to compare which ear perceives the sound louder, which helps distinguish types of hearing loss. The other instruments aren’t used for this test: an otoscope is for inspecting the ear canal and drum, a stethoscope is for listening to internal organs, and a reflex hammer is for testing reflexes.
