Audiology Testing Part 2
In last week’s blog post, we introduced you to two of the tests commonly used by the Audiologist at your visit to the Cleft and Craniofacial Clinic at Riley at IU Health. This week we conclude our discussion of the test battery that is used to determine the functional status of your child’s ears and how well your child is hearing.
After we have done a visual inspection and checked the functioning of the eardrum, it is time to do a behavioral hearing test in a sound booth. A behavioral test is used to determine the softest level of sound to which a person will respond. We use this to determine how well a patient can hear speech and sounds throughout the pitch range most important to understanding speech. We can test through speakers or headphones depending on the age and ability of the patient.
Finally, if necessary we would perform an objective test to determine how part of the inner ear system is working; it is called otoacoustic emissions or OAEs. This test allows us to have objective ear specific information that supplements other test information that has been obtained. Again, this test requires us to place an ear tip in the patient’s ear that will play some sounds while measuring that ear’s response to that sound as the patient sits quietly.
At times we may do some or all of the above tests, however, each child is unique and we will use our experience to determine which tests in the test battery are necessary and optimal to obtain the needed results.
As always, if you have any concerns about your child’s hearing, please don’t hesitate to ask to see an Audiologist!
