Hearing tests using tuning forks and gross screenings
Students use tuning forks in the Weber and the Rinne hearing tests.
In the Weber test the tuning fork is set in vibration and placed on the center of the head. If the patient heard better in the problem ear it could be a conductive hearing loss; if pt does not hear so well in the problem ear it could be a sensorineural hearing loss. The Rinne test compares the duration of sound perception by air conduction with that of bone conduction. The vibrating fork is placed against the mastoid process and then by the ear. A normal hearing patient hears the sound at least twice as long through air as through bone. If the pt hears the sound longer by bone conduction than by air it could be a conducive hearing loss. The gross screening is for air conductivity.
