Hear Lab
Cortical Analyzer

Cortical Auditory Evoked Potential (CAEP) measurements are used to estimate or detect whether particular sounds produce an electrical response in a patient′s brain.

CAEP can be tested on patients who are unable or unwilling to communicate which include infants and small children who have not yet developed language skills, and adults who are disabled or uncooperative. Cortical measurements are performed when the patient is alert and awake.

Applications of HEAR LAB in Pediatric Audiology

The widespread use of infant hearing screening has identified hearing loss in children at much younger ages than ever before. While greatly improving the hearing health care of these children, this practice has also brought new challenges to pediatric audiologists providing amplification for patients who do not have the ability to directly tell us what they are hearing.

After a child has been diagnosed with a hearing loss using otoacoustic auditory emissions (OAE) and auditory brainstem response (ABR) tests, the child may be fitted with hearing aids. This creates a challenge for pediatric audiologists: real-ear (and simulated real-ear) measurements can be used to measure the amplification provided by the hearing aid, but it is difficult to determine if that amplification is providing a benefit to the patient. One possible solution would be to perform an aided ABR test on the child. However, ABR testing has some fundamental drawbacks when performed with hearing aids.
