Weber test [va´ber]
a tuning fork test made by placing a vibrating tuning fork at some point on the midline of the head and noting whether it is perceived as heard in the midline (normal) or referred to either ear (middle ear disease). If it is heard better in the affected ear, there is conductive hearing loss; if it is heard better in the normal ear, there is sensorineural hearing loss.
Weber test. A, Normal—sound is equally loud in both ears; sound does not lateralize. B, Conductive loss—sound lateralizes to “poorer” ear owing to background room noise, which masks hearing in normal ear. “Poorer” ear (the one with conductive loss) is not distracted by background noise, thus has a better chance to hear bone-conducted sound. Examples: transient conductive loss with serous or purulent otitis media. C, Sensorineural loss—sound lateralizes to “better” ear or unaffected ear. Poorer ear (the one with nerve loss) is unable to perceive the sound. From Jarvis, 2000.
