Tests that we offer
- Pure Tone Audiometry: In this test pure tone is delivered in the ear of a child either with head phones or insert ear phones and the child is conditioned to respond to a sound by doing an action e.g putting a brick in the bucket. The quietest level the child responds to is plotted as the minimal response or Threshold. This is recorded in both ears for frequencies between 0.25 to 8 KHz. This type of testing gives ear specific information. (This can be done in babies if they will tolerate insert ear phones).
- Soundfield Conditioning or Play Audiometry: Similar to above but done in sound field without head phones, using a warbler and minimal responses are recorded. This test
will give minimal responses from the better hearing ear and is not ear specific. May require two people to test.
- Tympanometry which measures the mechanics of the tympanic membrane and the chain of bones behind it. This gives information if a child has fluid behind the ear drum, commonly called Glue ear.
- Middle Ear Muscle reflexes or Acoustic Reflex: These measure the response of the lower brainstem to sounds and depend upon the integrity of the middle ear, the cochlea
and cochlear nerve to elicit a response of the middle ear muscles via the facial nerve.
- Visual Response Audiometry: Here the child is conditioned to turn to a sound and every correct turn, i.e. when turns to a sound the baby is rewarded by a puppet or
TV screen lighting up as a reward. Requires two people to test. This, if done with insert ear phones, gives ear specific information with pure tones.
- Otoacoustic emissions OAE, which assess a faint sound coming from the outer hair cells. To be seen, these require a normal middle ear space and normal outer hair cells.
- Auditory Brainstem Response Test: This is an objective test which can give accurate hearing levels. Here a click sound or a tone is delivered in a childs ear via insert ear phones and the response generated in the brain stem and mid brain levels are recorded. We can also assess the synchrony of the auditory nerve and, when done with one positive and one negative polarity click, can separate the cochlear microphonic or Outer hair cell response from the synchronous discharge of the auditory nerve.
- Test for Auditory Processing: In some patients, the outer, middle, and inner ear appear to function normally, but they still have difficulty understanding speech in certain situations or learning in school. Screening tests for auditory processing disorders can help identify this type of problem so that a referral can be made for further testing. We offer an objective test where we record the brainstem response to a speech stimulus "da". This can be done when child is awake but has to lie still and can watch their favourite dvd. This test is developed by Dr Nina Kraus and is BioMark or BioMap.
