This is the most common routine test done for assessing Hearing Acuity and any Hearing Loss in Decibels. It also demonstrates the nature of Deafness, whether conductive (external or middle Ear Disease) or Perceptive (Sensory-Neural due to auditory nerve damage in the Inner Ear). Along with Pure tone Audiometry there are special tests like Speech Reception Threshold (SRT), Speech Discrimination Score (SDS), Free field Audiometry, Speech Audiometry, SISI, ABLB, Tone Decay etc. which give more clear picture about hearing status of a patient.

This is a test to identify Middle Ear Pressure, compliance of the Ear Drum and the Acoustic reflex which help to diagnose diseases like Middle Ear Fluid (Glue Ear), Fixation of smallest bones in the Middle Ear (Otosclerosis), Ossicular Dislocation and so on. All of the above tests are performed by computerized machines with high accuracy of reporting.

The babies who are born Deaf are likely to be Dumb or suffer from delayed speech development if earliest diagnosis and necessary management are not planned. Detection of Hearing Loss in new Children has gained much importance and in many places it is compulsory. There two most common hearing tests for early detection of deafness is OTO-Acoustic Emission (0.A.E.) & Brain Stem Evoked Response Audiometry (B.E.R.A.).

O.A.E. is a useful screening test for detecting Hearing Loss in the Newborn, but it cannot measure the degree of Hearing Loss. B.E.R.A (Brain Stem Evoked Response Audiometry) is also a computerized test for hearing loss of children. It takes more time to perform than O.A.E. but it is more accurate and also measures the degree of hearing loss.
