The purpose of the diagnostic audiological assessment (AE)/hearing test is to measure the softest sounds audible for tones at different frequencies and your ability to discriminate different words. During the test, you will be instructed to press a button every time you hear a soft tone. Your audiologist will measure the range of frequencies necessary to understand speech and common sounds, typically between 250 Hz to 8000 Hz.
Auditory Evoked Potential (AEP) testing is used to evaluate if certain components of the hearing and balance systems are functioning properly. Evoked potentials measure the time necessary for the nerves to respond to sound and electrical stimulus. They are used to rule out disease or damage to the auditory (hearing), vestibular (balance) or central nervous system and measure the health of the nerve pathway.
