Pediatric Testing in Columbia, TN

At Middle TN Hearing Aid Center, we care about you and your child.  Understanding your child’s hearing loss will help you research and be more aware as a parent.  We will walk you through every step to ensure you understand the process. 

Hearing loss can be present at birth or progress over time. It can be hereditary or acquired by environmental surroundings. In many cases, there are no known reasons for the hearing loss. The majority of children with hearing loss have no other abnormalities or distinguishing features (called non-syndromic hearing loss). Children who have late diagnosis of their loss may have significant consequences such as delays in language acquisition from the delay in diagnosis. Now, new guidelines allow hearing tests to be performed at birth to help avoid diagnosis.

Pediatric Audiology
Accurate testing in children can sometimes be difficult primarily due to a child’s inability to respond during standard testing. Other tests (ABR, OAEs) have been developed that require no direct response from children being tested. These tests are utilized in the hospital just after birth (universal screening) that is identifying children with hearing loss at an early age and allowing for early and appropriate therapy. Advances in genetic testing(molecular biology) has led to the ability to diagnose the cause of hearing loss in many felt to previously to have an unknown cause for their hearing loss.
Definition of severity of hearing loss

  • Hearing is measured in decibels (dB)
  • Normal (0-20dB)
  • Mild (41-55 dB)
  • moderately severe (56-70 dB)
  • Severe (71-90 dB)
  • Profound (90 dB or greater)

Diagnosis
The diagnosis of pediatric hearing loss requires careful history, family history and physical examination. Accurate assessment of the degree of hearing loss is essential to develop the appropriate treatment plan. Testing hearing in a young child with hearing loss can be difficult and require experience and significant expertise. There are multiple ways depending on the child’s age and severity of hearing loss that hearing can be tested.

Behavior testing
This test is given from birth to 6 months of age. As younger children cannot give the specific responses required in pure-tone audiometry, the child’s behavior is monitored during the test and compared to normal hearing children. This test requires experience and skill from the tester.

Conditioned play audiometry
This test is similar to behavior testing and is used to test children ages 2 ½ to five years of age. A more complete frequency-specific hearing test can be obtained from this method.

Pure–tone audiometry
This is a standard “hearing test”. This test determines the lowest tone at which a child can hear a specific tine at a specific frequency. For older children, speech can also be tested by presenting words as opposed to tones. Speech testing can give an accurate assessment of the ability to wear hearing aids.

Auditory Brainstem Response Testing (ABR, BSER, BAER)
ABR uses an auditory sound or stimulus from a probe placed in the ear to stimulate the hearing system and the response of this sound is measured by surface electrodes placed on the head. No responses are required from the child to measure these responses.

Evoked Otoacoustic Emissions (EOAEs)
OAE’s are sounds that are produced in the cochlea and measured with via probe in the ear canal. No responses are required from the child to measure these sounds.
Other tests depending on symptoms, family history, associated other medical problems, and physical examination may be obtained.
