However, there are benefits to using pure-tone audiometry over other forms of hearing test, such as click auditory brainstem response (ABR). [3] Pure-tone audiometry provides ear specific thresholds, and uses frequency specific pure tones to give place specific responses, so that the configuration of a hearing loss can be identified.
The test is also useful in older children and adults and is an important measure in diagnosing auditory neuropathy described above. Auditory brainstem response testing is an electrophysiological test used to test for hearing deficits caused by pathology within the ear, the cochlear nerve and also within the brainstem.
The Weber test is administered by holding a vibrating tuning fork on top of the patient's head. The Weber test is a screening test for hearing performed with a tuning fork. [1] [2] It can detect unilateral (one-sided) conductive hearing loss (middle ear hearing loss) and unilateral sensorineural hearing loss (inner ear hearing loss). [3]
This test helps the audiologist determine whether the hearing loss is conductive (caused by problems in the outer or middle ear) or sensorineural (caused by problems in the cochlea, the sensory organ of hearing) or neural - caused by a problem in the auditory nerve or auditory pathways/cortex of the brain.
Audiologists and speech-language pathologists are professionals who typically provide aural rehabilitation components. The audiologist may be responsible for the fitting, dispensing and management of a hearing device, counseling the client about his or her hearing loss, the application of certain processes to enhance communication, and the skills training regarding environmental modifications ...
Auditory neuropathy can be diagnosed with a battery of tests including otoacoustic emissions (OAE), auditory brainstem response (ABR), and acoustic reflexes. The classic AN paradigm would include present OAEs indicating normal outer hair cell function, absent or abnormal ABR with presence of the cochlear microphonic, and absent acoustic reflexes.

Audiometry (from Latin audīre 'to hear' and metria 'to measure') is a branch of audiology and the science of measuring hearing acuity for variations in sound intensity and pitch and for tonal purity, involving thresholds and differing frequencies. [1]
