Why is more than one hearing screening test necessary?
Hearing loss in an infant or child cannot be confirmed with one test alone. Several tests must be done to check different parts and different functions of the ear. Audiologists refer to a group of tests as a battery of tests. Because Behavioral Audiometry Evaluation tests the function of all parts of the ear, it is considered fundamental to the battery of tests used to evaluate older infants and children for hearing loss. However, because this test relies on behavior and the cooperation of the infant, it is not reliable until the child reaches the developmental age of 5 to 6 months. For children younger than 5 to 6 months of age and for children who are developmentally delayed, ABR testing is considered the most important of these tests.
