Pure Tone Audiometry
Pure-tone audiometry is a behavioral test used to measure hearing sensitivity. This measure involves the peripheral and central auditory systems. Pure-tone thresholds (PTTs) indicate the softest sound audible to an individual at least 50% of the time Pure Tone Audiometry Test is the first step towards evaluation of hearing loss. This audiometry test is undertaken

Impedance audiometry is primarily used to test the condition of the middle ear along with the mobility of the eardrum. This audiometry test is also known as Tympanometry and is considered as one of the most accurate methods for testing the middle ear. When the impedance audiometry test procedure starts, the patient is requested to

Brain stem evoked response audiometry (BERA) is an effective method of evaluating the auditory pathway through the brain stem. Brainstem auditory evoked response (BAER) is a test to measure the brain wave activity that occurs in response to clicks or certain tones. The test is done to: Help diagnose nervous system problems

An auditory steady-state response (ASSR) is an electrophysiological response that is evoked by a periodically repeated (rapid) auditory stimulus. The auditory steady-state response (ASSR) is an auditory evoked potential, elicited with modulated tones, that can be used to predict hearing sensitivity in patients of all ages. The auditory steady-state response (ASSR) can be thought of

OAEs are sounds of cochlear origin, which can be recorded by a microphone fitted into the ear canal. Our ear is made up of three parts—the outer, the middle, and the inner ear. The OAE test is used to find out how well your inner ear, or cochlea, works. It measures otoacoustic emissions, or OAEs.

Visual Reinforcement Audiometry is a key behavioural test for evaluating hearing in young children. Visual reinforcement audiometry (VRA) is a test that allows an audiologist to assess hearing in infants and toddlers too young for normal tests. VRA relies on behavioral conditioning to train very young kids to respond to sounds. It is designed for
