Hearing Evaluation

PTA (Pure Tone Audiometry)

Pure Tone Audiometry (PTA) is an important examination of ears. This test is carried out to identify the hearing capacity of an individual that has been suffering from loss of hearing. After the test is completed the size and length of hearing loss can be judged.

Tympanometry

Tympanometry is a very useful assessment of ears and their hearing capacities. Under this, the condition of the middle area of ear and the mobility of the eardrum is tested. This process is done through the route of ear canal. This particular test helps in making distinction between sensorineural and conductive hearing loss.

Speech Audiometery

Speech threshold audometery is procedure used in the assessment of individual’s threshold of hearing for speech.

Special Tests

Short Increment Sensitivity Index (SISI) Tone Decay Test Tinnitogram.

New Born Hearing Screening

Purpose Of Newborn Hearing Screening

Before you bring your newborn home from the hospital, your baby needs to have a hearing screening.

Although most babies can hear normally, 1 to 3 of every 1,000 babies are born with some degree of hearing loss. Without newborn hearing screening, it is difficult to detect hearing loss in the first months and years of your baby’s life.

Newborn hearing screening can detect possible hearing loss in the first days of a baby’s life.

 If a possible hearing loss is found, further tests will be done to confirm the results.

When hearing loss is confirmed, treatment and early intervention should start as soon as possible.

If Hearing Loss Is Found, What Can Be Done?

Brainstem Evoked Response Audiometry (BERA) :-
It is a test measuring responses in the brain waves that are stimulated by a clicking sound to check the central auditory pathways(hearing) of the brainstem.

Electrocochleography’ (ECochG):-
It is a method for recording the electrical potentials of the cochlea. ECochG generally involves measurement of the stimulus-related cochlear potentials (as opposed to the resting potentials), and often includes measurement of the whole nerve or compound action potential (AP) of the auditory nerve.

The test is performed by an otologist or audiologist with specialized training, and is used for detection of elevated inner ear pressure (endolymphatic hydrops) or for the testing and monitoring of inner ear and auditory nerve.
