Clinical Evaluation of Hearing

Show Summary Details

Preview

Hearing loss for pure tones is typically divided into conductive and sensorineural; central lesions rarely produce such hearing loss. Conductive and sensorineural loss can usually be differentiated with an audiogram based on the finding of an airbone gap with the former and a characteristic frequency intensity profile with the latter. The causes of a conductive hearing loss can be differentiated with tympanometry. There are several test results that help distinguish between a cochlear and retrocochlear sensorineural hearing loss.
