Evaluation of Hearing with a Tuning Fork
There are three types of hearing loss: conductive, sensorineural, and mixed.
Differentiation between sensory (cochlear) and neural (cranial nerve VIII)
sensorineural
hearing loss is important. Evaluating hearing with a tuning fork can be a useful
clinical screening tool to differentiate between conductive and sensorineural hearing
loss. By comparing the threshold of hearing by air conduction with that elicited by
bone conduction with a 512-Hz tuning fork, one can infer the site of the lesion
responsible for hearing loss. The Rinne and Weber tuning fork tests are used widely
both to differentiate conductive from
sensorineural hearing losses and to confirm the audiologic evaluation results.
