Behavioral Observation Audiometry (BOA): This is a screening tool used to determine if an infant's response to sounds is age-appropriate.
Visual Reinforcement Audiometry (VRA): A pediatric hearing test used to obtain information regarding hearing sensitivity of infants and young toddlers, aged five months to about two and a half years old. VRA uses lighted and/or animated toys that are flashed on to reinforce correct identification of the direction of the auditory signal (warble tones, narrow band noise or speech).
Conditioned Play Audiometry (CPA): A pediatric hearing test used to obtain information regarding hearing sensitivity of young children, aged two and a half to four years old. During CPA testing, the child places a small toy in a bucket or game in response to an auditory signal (pure tone, speech).
Otoacoustic Emissions Testing (OAE): Quickly identifies hearing impairments in difficult-to-test populations. It is now the standard procedure utilized in infant hearing screenings. OAEs also identify an array of cochlear pathologies including early hearing loss from noise exposure or ototoxic drugs.
Tympanometry: measures middle ear pressure and mobility of the tympanic membrane. It can identify or confirm otitis media, perforation of the tympanic membrane, ossicle fixation, ossicular discontinuity, Eustachian tube dysfunction and ventilation tube patency.
Auditory Brainstem Response (ABR): An objective test that can be used to estimate hearing sensitivity and to identify neurological abnormalities of the auditory nerve and the auditory pathway up through the brainstem.
