Hearing is very important to connect ourselves with the auditory world. Individuals who have hearing difficulty should undergo complete hearing evaluations. Hearing evaluation is also known as audiologic evaluation, which includes tests done by an audiologist to give information about
  • Whether a hearing loss is present,
  • Which frequencies (or pitches) are affected?
  • How severe the hearing loss is, and
  • The type of hearing loss.
A comprehensive audiology test battery involves:
  • Play audiometry (upto 3 yrs of age)
  • Pure tone audiometry (3yrs & above)
  • Immittance audiometry
  • Tympanometry
  • Acoustic reflex audiometry
  • Eustachian tube function test
  • Auditory Brainstem Response (ABR)/Brainstem Evoked Response Audiometry (BERA)
  • Otoacoustic Emissions (OAE)
The evaluation will also include recommendations from the audiologist regarding the choice of hearing aid for the patient.

Oto Acoustic Emissions (OAE)

Otoacoustic Emissions (OAE) is used as a screening tool for hearing in neonates or new born children. OAE test is very useful for the assessment of hearing defects in newborn babies and in children who are too young to cooperate in conventional hearing tests.

Brainstem Evoked Response Audiometry (BERA)

BERA is an objective test. In this test, evoked potentials in brain and the auditory pathway are collected from ongoing electrical activity with the help of electrodes placed over the scalp.

BERA is used for newborn hearing screening, auditory threshold estimation, intraoperative monitoring, determining hearing loss type, degree, and auditory nerve and brainstem lesion detection.

Immittance Audiometry {IA)

IA is a measurement of the middle ear functions. It provides information about the movement of eardrum, status of middle ear and type of hearing loss

Pure tone Audiometry (PTA)

PTA is a subjective test, used for the assessment of the Hearing Sensitivity of an Individual. It provides information about the hearing sensitivity in terms of the Degree and Type of the hearing loss.
