Which two common tests are used to evaluate hearing in infants?

The two common tests used to evaluate hearing in infants are otoacoustic emissions (OAE) and auditory brainstem response (ABR). Both of these tests are non-invasive and specifically designed to assess auditory function in young children, including those who may not yet be able to respond verbally or follow instructions.

Otoacoustic emissions measure the sound waves produced by the inner ear (cochlea) in response to auditory stimuli, indicating that the cochlea is functioning properly. This test is particularly useful for newborn hearing screening, as it can effectively identify hearing loss shortly after birth.

Auditory brainstem response, on the other hand, evaluates the electrical activity of the auditory nerve and brainstem in response to sound. This test is beneficial for assessing auditory pathways in the brain and can detect issues that may not be apparent with other testing methods.

These two tests together provide a comprehensive evaluation of an infant's hearing capability, ensuring early detection of hearing impairments, which is crucial for effective intervention and support. Other options listed involve testing methods that are less suitable for infants or do not primarily focus on hearing assessments specific to their age group.
