Cardon Children's Medical Center provides a full range of audiology services for children of all ages. Our staff works to ensure patients and families receive family-centered care, in a child-friendly and nurturing environment.

All of our audiologists are doctorate-level trained. For children under the age of 5, or children who are developmentally delayed, we can offer two examiners to ensure we provide the most accurate test information possible.

Comprehensive diagnostic evaluations are provided for children from birth to 21 years of age, in both inpatient and outpatient settings. Spanish and American Sign Language/Signed English interpreters are available upon request.

Patient and Family Resources

Assistive Listening Devices are products that help patients with and without hearing aids to hear better in their daily lives. Some devices adapt to hearing aids; others are used without hearing aids. These devices assist patients to communicate on the telephone, in large groups, with television viewing, etc.

Behavioral Audiological Testing (using two examiners when appropriate) is completed by performing various listening tasks in a sound-proof booth.  The type of testing depends upon the patient’s developmental level.

Central Auditory Processing Evaluations (APD) are appropriate for children ages 8 and up. Testing takes approximately three hours. Your child will be given a battery of tests with both speech and non-speech stimuli; all they need to do is respond or repeat when asked. Children with APD usually have normal hearing but difficult processing speech and/or sounds in the brain.  In other words, they have difficulties recognizing, understanding, and interpreting what is heard. Specific recommendations to improve abilities will be made based upon your child’s test results.

Custom ear molds, swim molds, noise plugs are created by taking an impression of the patient’s ear. The impression is sent to a lab where a custom mold is made to user specifications. Our molds are available with hypo-allergenic material in a variety of colors and styles. Our custom noise plugs are often used by patients working in noise. Special filters are available for musicians who need their surroundings attenuated without losing sound quality.

Hearing Aid Services involve the selection and dispensing of ear molds, hearing aids and assistive listening devices. State-of-the-art equipment is used to program hearing aids to the patient’s degree of hearing loss and listening needs. Hearing aid repair services are also available. 

Immittance Testing yields information about how the middle ear structures are working. A small tip is placed in the ear canal and a computer measures the middle ear responses to air pressure changes and tones. 

Non-sedated and Sedated Auditory Brainstem Response (ABR) Testing measures how well each ear picks up sounds by evaluating  responses to signals sent to the hearing nerve. These responses are recorded and measured on a computer. The test does not require participation from the child. 

Children need to be asleep for the test. If your child is scheduled for testing without sedation, you can help us by not allowing him/her to sleep during the 2-to-4 hour period preceding their test.

Children older than 4 months of age are sedated for this test. You will be contacted prior to your appointment for specific pre-testing instructions.

Otoacoustic Emissions (OAEs) are sounds generated from outer hair cell structures within the cochlea, which is part of the inner ear. A small probe measures these responses within a few minutes.  The child is not required to tell or show that sounds are heard. OAEs help the audiologist in evaluation and diagnosis of hearing.
