Air conduction should be greater than bone conduction, so the patient should be able to hear the tuning fork next to the pinna (outer ear) after they can no longer hear it when held against the mastoid. This normal result is paradoxically called a positive Rinne test (as a positive medical test usually indicates an abnormality).
Negative Rinne; bone conduction > air conduction (bone/air gap) Other, more complex, tests of auditory function are required to distinguish the different types of hearing loss. Bone conduction thresholds can differentiate sensorineural hearing loss from conductive hearing loss.
For basic screening, a conductive hearing loss can be identified using the Rinne test with a 256 Hz tuning fork. The Rinne test, in which a patient is asked to say whether a vibrating tuning fork is heard more loudly adjacent to the ear canal (air conduction) or touching the bone behind the ear (bone conduction), is negative indicating that ...
The Rinne test is used in cases of unilateral hearing loss and establishes which ear has the greater bone conduction. Combined with the patient's perceived hearing loss, it can be determined if the cause is sensorineural or conductive. For example, if the Rinne test shows that air conduction (AC) is greater than bone conduction (BC) in both ...
The standard and most common type of hearing test is pure tone audiometry, which measures the air and bone conduction thresholds for each ear in a set of 8 standard frequencies from 250Hz to 8000Hz. The test is conducted in a sound booth using either a pair of foam inserts or supraural headphones connected to an external audiometer.
By Leah Douglas and Julie Steenhuysen (Reuters) -California's public health department reported a possible case of bird flu in a child with mild respiratory symptoms on Tuesday, but said there was ...
The Rinne test is a hearing test conducted with a tuning fork, and is used to test and compare a patients' hearing via air conduction (normal process) or by way of bone conduction (sound to the inner ear through the mastoid). He reasoned that if a person hears a sound for a longer period of time through bone conduction than through air ...
