Hearing Evaluation for Adults

An Audiometry is a test used to assess the hearing level of a person that tests both intensity and tone (Pitch) of sounds to determine how good a person’s hearing is.

Audiometry test is performed as a part of routine health check up or in response to a noticeable hearing loss which measures the hearing capacity of an individual.
Audiometry is used in a number of different circumstances including:
  • Evaluate possible hearing loss in people who have difficulty in understanding words in conversation.
  • To determine the type and degree/severity of hearing loss (conductive, sensorineural, or both).
  • To screen for hearing loss in people who are repeatedly exposed to loud noises or who are taking certain Ototoxic drugs.

Immitance Audiometry

Purpose of immitance audiometry is to determine the status of the tympanic membrane (ear drum) and middle ear by tympanometry test.
Tympanometry test enables us to determine how well the conducting part of the ear (from the external canal and includes the middle ear) is functioning. The test will help to identify middle ear pathology.
Tympanometry allows Eljay’s expert audiologist’s to measure how well the eardrum is vibrating when sound strikes besides the functioning of the tiny bones of the ear in transmitting those vibrations to the ear. It also helps in measuring the pressure in the space behind the eardrum that contains those bones. Any unusual findings on this test may indicate a conductive/ mixed loss requiring ENT evaluation.
Acoustic reflexes is another part of the Immitance test. Acoustic reflex measurement allows the audiologist to further examine the integrity of the middle ear system. For this test, very brief, somewhat loud tones are presented to each ear, to determine whether an acoustic reflex is present or absent, without requiring any response from the patient. In a normal-hearing ear, the stapedius muscle in the middle ear contracts involuntarily in response to loud sounds presented at levels of about 70-100 dB (decibels).
