Final answer:
The tuning fork test used to assess hearing between two positions is the Rinne test, which helps differentiate between conductive and sensorineural hearing loss. Conductive hearing loss is identified if sound is conducted better through bone than air, whereas the Weber test uses a tuning fork placed on the skull to further differentiate the type of hearing loss.
Step-by-step explanation:
The test that uses a tuning fork between two positions to assess hearing is the Rinne test. This test determines whether a person has conductive or sensorineural hearing loss. A tuning fork is first placed on the mastoid process behind the ear (bone conduction), and when the sound is no longer heard, it is then moved next to the ear canal (air conduction). If the sound is not heard through the ear, indicating better conduction through bone than air, this suggests a conductive hearing deficit.
Another test using a tuning fork is the Weber test, which differentiates between types of hearing loss by placing the tuning fork on the top of the skull. This test is conducted by examining how sound is perceived: equally in both ears, louder in the affected ear with conductive loss, or quieter in the affected ear with sensorineural loss.
