No, the world apparently sounds very different to infants than it does to adults. Several methods can be used to test hearing, depending on a child's age, development, and health status. A baby's hearing evaluation may include the OAE, ASSR and ABR (BERA) tests. Ideally these tests are used with Behavioral Audiometery:
- Behavioral audiometry.A screening test used in babies to watch their behavior in response to certain sounds.
During behavioral tests, an audiologist carefully watches a child respond to sounds like calibrated speech (speech that is played with a particular volume and intensity) and pure tones. A pure tone is a sound with a very specific pitch (frequency), like a note on a keyboard.
An audiologist may know an infant or toddler is responding by his or her eye movements or head turns. A preschooler may move a game piece in response to a sound, and a grade-schooler may raise a hand. Children can respond to speech with activities like identifying a picture of a word or repeating words softly.
