Audiology (Hearing)

Our doctors of audiology, known as “audiologists,” provide testing for children of all ages and developmental levels. Test results give the audiologist information on any hearing problem as well as the need for referral to another specialist. 

What is an audiologist?

Audiologists (au-di-ol-o-gists) specialize in the diagnosis, management and treatment of hearing and balance disorders. They provide direct service for people of all ages and abilities, from newborns to the elderly, in schools, private clinics, and hospitals.

What we offer

We provide the full range of audiology testing and services. The tests are detailed below.

We also provide family education regarding auditory and communication development, hearing conservation, hearing loss, and educational programming.

We are able to coordinate all aspects of care, from inpatient through outpatient, for children at Randall Children’s Hospital.  We also provide analysis and interpretation of test results and implications for communicative, educational, and social development.  We work collaboratively with family, physicians, interdisciplinary clinics and outside parties such as early intervention and school personnel.

Note: Our staff does not currently dispense hearing aids; rather we work with our community partners to ensure that children receive the assistance they need.  


We provide the full range of audiology testing and services.

  • Behavioral tests for those children who are old enough to respond to sounds by turning their head, playing a game, raising their hand, or repeating words. Among these:
    • Visual reinforcement audiometry (VRA)
    • Conditioned play audiometry (CPA)
    • Standard audiometry
    • Speech audiometry, including word recognition testing
    • Periodic monitoring of hearing for children on ototoxic  medication and  for children with chronic illnesses or medical conditions that put them at greater risk for hearing loss
    • Auditory processing testing


  • Physiologic tests for those too young to respond or cannot perform a behavioral test, or when we need to double check the behavioral responses against a more objective test. Among these:
    • Newborn hearing screening and diagnostic follow up
    • Otoacoustic emissions (TEOAEs and DPOAEs)
    • Middle ear studies, such as tympanometry and acoustic reflex testing
    • Auditory evoked potential testing: auditory brainstem response (ABR or BAER) under natural sleep. This is a sleeping test. Small disk-like sensors called electrodes are placed onto the head, and foam tips are put in the child’s ears. Different clicking sounds are presented to one ear at a time. This test measures the hearing nerve activity in response to the sounds. This test is painless and takes approximately two-three hours, depending on how well the child sleeps. If the child is not expected to sleep naturally, sedation can be given by an anesthesiologist. A pediatric nurse is also present to help monitor your child while the test is done (This is a sedated ABR)

    • Auditory steady state response (ASSR). This is very similar to the ABR and is also a sleeping hearing test that measures an electrical response of the inner ear and auditory nerve. The test can be done either in natural sleep or with the use of a mild sedative, along with sleep deprivation techniques.


Our location

Newborn hearing screening services are found at several of Legacy’s facilities. Pediatric audiology care is found on the Legacy Emanuel campus, with outpatient testing conducted in Legacy Emanuel Medical Center and inpatient testing within Randall Children’s Hospital.

For our outpatient adult patients, we partner with the Clinical Audiology and Vestibular Lab at Legacy Good Samaritan Medical Center.
