What are Cortical Measurements? Cortical Auditory Evoked Potential (CAEP) measurements are used to estimate whether sounds are easily detectable by the patient. HEARLab provides the audiologist with an easy to use method of performing this measurement. A transducer such as an insert earphone, bone vibrator, or sound field speaker is used to deliver test signal to the patient. Electrodes placed on the patient's head measure the cortical response. A statistical analysis of each response (a "p-value") is automatically calculated to determine the likeliness that the patient detected the test signal. The audiologist can verify this analysis with a visual examination of the measured cortical response. CAEP can be tested on patients who are unable or unwilling to communicate to the clinician about whether they can hear a signal. This could include infants who have not yet developed language skills, and adults who are disabled or uncooperative. The relationship between the presence of cortical responses and the audibility of sounds has so far been established only for infants aged 8 to 30 months and for adults aged 43 to 89 years. Cortical measurements are performed when the patient is alert and awake. Adults can be entertained during the test with reading material or a silent DVD. Infants can be entertained with a quiet toys.
