Audiology – is derived from a Latin word called audīre, means “to hear”, is the branch of science that studies hearing, balance, and related disorders.
Audiology aims to determine whether someone can hear within the normal range, and if not, which portions of hearing (high, middle, or low frequencies) are affected and to what degree. Audiologists are experts in the management of the auditory and balance systems.
There are number of tests available to determine the degree and type of hearing loss e.g. PTA, Impedance, OAE, BERA, ASSR etc. Once the diagnosis is confirmed with these test the patient is referred to the ENT Specialist for management of the hearing loss.
It is important to remember that these tests are ‘Non Invasive’ and do not cause any pain!
Pure Tone Audiometry (PTA)
Pure tone audiometry is a hearing test used to determine the presence or
absence of hearing loss and also the type and severity of hearing loss. This test involves placing earphones on both ears and pressing a button or raising your hand when you hear a sound.
Speech audiometry is a test using words to determine how softly words can be heard and how clearly words are understood. You will listen to a list of words and repeat them back to the Audiologist. The words lists are presented at different intensities. The results of word understanding are measured by a percentage score. The main purpose of this test is to check the ability to recognise speech.
Assists in the detection of fluid in the middle ear, perforation of the eardrum, or wax blocking the ear canal.
Tympanometry pushes air pressure into the ear canal, making the eardrum move back and forth. The test measures the mobility of the eardrum. Graphs are created, called tympanograms. These can reveal a stiff eardrum, a hole in the eardrum, or an eardrum that moves too much.
Otoacoustic Emission (OAE) Testing
The otoacoustic emissions (OAE) test that check the outer hair cell function of the inner ear(cochlea) to estimate hearing sensitivity. It is now used as a new born screening test.
The ABR test The ABR test is used to test the functional status of the auditory neural pathway (how sounds travel to the brain) and to assess hearing when behavioural testing cannot be performed due to age, cooperation, or developmental level.
– as a screening procedure for newborns who are at risk for hearing loss.
– as a diagnostic tool to identify infants and small children with a hearing loss.
– to estimate hearing levels in difficult to test patients, i.e., mentally retarded, autistic, developmentally delayed.
Testing for Vertigo
The Centre has an advanced Vestibular testing Lab to evaluate patients of Vertigo/ Giddiness.
